Quick answers

What are the best jammer arms for a home gym?

The Titan T-3 Series Adjustable Lever Arms for 2×3 inch Titan racks, the REP ISO Arms for REP 4000 and 5000 Series racks, and the Bells of Steel Lever Arms for 2.3 inch and 3×3 inch racks with matching holes.

Are jammer arms and lever arms the same thing?

Yes. Titan, Bells of Steel, Mikolo and RitFit sell them as lever arms, REP calls them ISO Arms and PRx calls them Halo Arms. All are plate-loaded arms that pivot from your rack upright.

Jammer arms turn a power rack into a plate-loaded press and row machine. Each arm pins to an upright, pivots near the rack, and carries a weight horn and handle at the far end, so you can do standing presses, jammer presses, rows, shrugs, squats and lunges on a fixed arc without buying a separate machine. For a home gym that already has a cage, they are one of the few attachments that add a whole new category of training without adding floor space. The catch is fit and leverage: the arms are sized to one rack line, and a 39 inch arm loaded with plates puts real tipping force on the uprights. Below we compared eight jammer arm sets on fit, listed capacity, arm length, steel and warranty, then ranked them for real home gyms. Still choosing the rack?

Jammer arms compared: fit, capacity and size

The table shows what each maker lists: the rack the arms are built for, the hole size, the listed capacity, the arm length and the weight of the arm. “Not stated” means the number was not on the product page we read. Capacity is the maker’s figure for the arm, and your rack and how it is anchored still set the real limit.

1. Titan T-3 Series Adjustable Lever Arms: best overall

Key specs: 2×2 in 11-gauge steel tubing, 600 lb capacity per arm, 39 in arm length, 30 lb per arm, 50 mm sleeve with an 11.5 in weight post, 32 mm multi-grip handles (7 in vertical, 3 to 5 in horizontal), pin-on brackets, rubber bumpers, bushings at the hinge, 1-year warranty.

The T-3 Lever Arms rank first because they pair the highest listed capacity in this comparison, 600 lb per arm, with one of the most common home racks. The T-3 Series is a 2×3 inch, 11-gauge rack that shows up in a lot of garages, so these are the jammer arms the largest number of readers can actually bolt onto. At 30 lb per arm they are also light enough to move between a high pressing position and a low position for squats, deadlifts and shrugs without a fight.

The 32 mm handles give you both a vertical and a horizontal grip, which covers neutral-grip presses and rows as well as pronated work. The 11.5 inch post takes a good stack of Olympic plates, and the 50 mm sleeve matches standard plate holes. Two lines on Titan’s page matter before you order: the arms are not compatible with T-3 racks bought before October 2021, and Titan recommends using lever arms only on a rack that is bolted down. The 1-year warranty is shorter than Bells of Steel’s, which is the main thing holding this pick back on paper.

Best for: Titan T-3 owners who want the most capacity for a 2×3 rack. Skip if: your T-3 is older than October 2021, your rack cannot be anchored, or you own a different brand.

2. REP Fitness ISO Arms: best for REP racks

Key specs: 3×3 in 11-gauge steel, 42 in long and 30.87 in wide with horn and handle, 2 in diameter weight horn 12.8 in long, 5/8 in holes (4000 Series) or 1 in holes (5000 Series), attachment weight 66.2 lb (4000) or 68.4 lb (5000), spring clips included.

The ISO Arms are the jammer arms most REP rack owners end up with, and they earn the spot through range of use. They mount to the outside of a compatible REP rack, the handle adjusts up, down and in other orientations, and the arms can be locked in place for dips, L-sits and pull-up variations. That makes them a press and row station, a dip station and a pull-up add-on in one attachment.

REP does not print a pound rating. Instead, its FAQ says the 3×3 inch, 11-gauge arms fit up to seven 45 lb iron plates on each arm, which tells you the horn length is generous. At 42 inches, they are the longest arms here, which means a long, smooth arc for presses and more room for tall lifters, but also the biggest swing radius in front of your rack. REP notes that its standard spring clips are too big for the horns, so use the clips that come in the box. Pick the 4000 version for 5/8 inch holes and the 5000 version for 1 inch holes.

Best for: REP 4000 and 5000 Series rack owners who want presses, rows, dips and pull-ups from one attachment. Skip if: you do not own a REP rack, or your floor space in front of the rack is tight.

3. Bells of Steel Lever Arms: best value for 3×3 racks

Key specs: 11-gauge steel, 500 lb capacity, 39.1 in long, 3.6 in wide, 8.5 in tall, 48 mm (1.9 in) sleeve, sold in pairs with or without closed handles, three versions: 2.3×2.3 in with 5/8 in holes, Hydra 3×3 in with 5/8 in holes, Manticore 3×3 in with 1 in holes. Limited lifetime warranty.

Bells of Steel sells the only jammer arms here in three fit versions across two upright sizes, and backs them with a limited lifetime warranty, the strongest coverage in this comparison. You can buy the arms with closed handles, the arms alone or the handles alone, which lets you start smaller and add pieces. The 500 lb rating sits below Titan’s 600 lb per arm, but it is still far more than most home lifters will load on a single arm.

Bells of Steel also gives the most useful space facts. Folded up, the arms add only 4.5 inches to the front of the rack, and they tuck inside racks with a minimum 43 inch depth. If you mount them on the outside of the uprights, the rack must be bolted down to avoid tipping. Note the fit warning too: the Hydra arms are only guaranteed on true 3×3 inch uprights with 5/8 inch holes, so measure before you assume a 3×3 rack from another brand will work. The 48 mm sleeve takes Olympic plates but is slightly slimmer than the 50 mm sleeves on the Titan arms.

Best for: Bells of Steel rack owners and anyone with matching 2.3 inch or 3×3 inch uprights who wants a lifetime frame warranty. Skip if: your rack is 2×2 or 2×3 inches.

4. Titan X-3 Series Adjustable Lever Arms: best for Titan 3×3 racks

Key specs: 3 in 11-gauge steel tubing, 600 lb capacity per arm, 39 in arm length, 45 lb per arm, 50 mm sleeve with an 11 in weight post, 32 mm multi-grip handles (7.5 in vertical, 3 to 5 in horizontal), pin-on brackets, rubber bumpers, 1-year warranty.

The X-3 version is the T-3 design scaled up for Titan’s 3×3 inch X-3 racks. Capacity stays at 600 lb per arm and arm length at 39 inches, but the arm itself uses 3 inch tubing and weighs 45 lb per arm, 15 lb more than the T-3 version. That extra steel makes for a stiffer arm under heavy presses, at the cost of a little more effort when you move them between positions.

Everything else matches the T-3 version: the 50 mm sleeve, the 32 mm handles with vertical and horizontal grips, the rubber bumpers that protect the uprights and Titan’s advice to use lever arms only on a bolted-down rack. It ranks fourth only because it fits one rack line. If you own an X-3, it is the first set to look at.

Best for: Titan X-3 owners. Skip if: you own any other rack.

5. Mikolo Adjustable Lever Arms (JA01): best for Mikolo racks

Key specs: Fits Mikolo 3×3 in P5 power racks, 1 in hole size, 600 lb capacity, 33 lb each, bearing pivot with a 180-degree arc, four-way hole pattern, lockable for dips and pull-ups, rubber bumpers, 3.94 in between the two mounting pins, for 2 in plates only.

Mikolo’s lever arms match Titan’s 600 lb figure in a 3×3 inch design and add a bearing at the pivot that Mikolo says gives a full 180-degree arc. The four-way hole pattern lets you slide the arm into different positions or add J-cups, and the 1 inch holes also take Mikolo’s belt squat attachment. Like the REP arms, they can be locked in place for static moves such as dips and pull-ups, then locked upright and out of the way when you are done.

The fit is narrow: Mikolo lists them for its P5 power racks, and they mount on the outside of the rack. They take 2 inch Olympic plates only. Mikolo does not list an arm length, so measure the space in front of your rack against the other arms here (39 to 42 inches) before you buy.

Best for: Mikolo P5 owners who want dips, pull-ups and plate-loaded presses from one pair. Skip if: your rack is not a Mikolo P5.

6. PRx Profile Halo Arms: best for PRx folding racks

Key specs: 220 lb capacity per arm, 37.5 x 4 x 9.5 in, 41 in long when perpendicular to the rack, 2×3 in tube, 5/8 in or 1 in bracket versions, 12 in weight post, 6 vertical and 5 horizontal adjustment points, 30 lb per arm, wall storage included, fits all PRx squat racks.

The Halo Arms are the most flexible design in this comparison. With five vertical and horizontal locking positions you can set a fixed arc like a classic jammer arm, or pull the pins and get free motion for converging and diverging presses. They attach with two pins on a C-channel bracket, and when you are done they hang on the included wall storage, which suits a PRx folding rack that you fold flat after every session.

The tradeoff is capacity. PRx lists 220 lb per arm, the lowest figure here after the RitFit, so these are built for volume and variety more than for maximal pressing. PRx also warns that dropping the arms against an upright can damage it. Choose the bracket that matches your rack’s holes, 5/8 inch or 1 inch.

Best for: PRx Profile rack owners who want free-motion presses and a clean wall after training. Skip if: you want to load the heaviest possible weight per arm.

7. Force USA Jammer Arms: best for all-in-one trainers

Key specs: Fits 2×2 in uprights on every Force USA G and C Series all-in-one trainer, sold in pairs, 5/8 in pins for G1-V2, G3-V2, G10, G12-V2, G15, G20-V2 and C10, 1 in pins for G6-B, G9 and G12, lifetime frame warranty, 2-year parts warranty.

If your home gym is built around a Force USA all-in-one trainer, these are the jammer arms made for it. Force USA designed them to be more compact than typical jammer arms, they are quick to attach and adjust, and they come with multiple grip positions for chest, shoulder, arm and back work. The lifetime frame warranty with 2 years on parts is better coverage than Titan’s.

Force USA does not list a capacity or arm length on the page we read, so we could not rank them higher on specs. Check that your trainer is on the pin list above, since the 5/8 inch and 1 inch versions are not interchangeable.

Best for: Force USA G and C Series owners. Skip if: you own a standalone power rack.

Spec source: Force USA Jammer Arms product page, read October 2026.

8. RitFit LAM1 Adjustable Lever Arm: best for RitFit M1 PRO

Key specs: For the RitFit M1 PRO only, 260 lb static load capacity, 130 lb per detachable weight horn, 31.5 in lever arm, 10.51 in horns, Q235 steel 2×2 in tube, 9-position swivel dial, 5-position handle at 15 degrees per step, dual locking pins and an anti-drop strap, suggested user height 4 ft 9 in to 6 ft 5 in.

The LAM1 is a different take on the idea. Instead of two long arms, it uses a single shorter arm with two detachable weight horns, and you change the leverage by moving the horn along the arm: lower feels heavier, higher feels lighter. The 9-position dial sets the start angle, and dual pins plus an anti-drop strap hold it on the rack.

It ranks last for two reasons: it fits only the RitFit M1 PRO, and its 260 lb static rating (130 lb per horn) is the lowest in this comparison. For M1 PRO owners training mostly with moderate loads, it is still a tidy way to add presses and rows.

Best for: RitFit M1 PRO owners. Skip if: you own any other rack or plan to press heavy.

Also brand-locked: Major Fitness sells 2×3 inch lever arms that it lists only for its own PLM03, F22, F35, B52 and B17 machines, with plate loading or a cable connection. Major Fitness says they are not compatible with other brands, and the page we read gave no capacity, so we left them out of the ranking. See the Major Fitness Lever Arms.

Which jammer arms are right for you?

• You own a Titan T-3: the T-3 Series Adjustable Lever Arms, if your rack is from October 2021 or later.
• You own a Titan X-3: the X-3 Series version, same 600 lb per arm in thicker 3 inch tube.
• You own a REP 4000 or 5000 Series rack: the ISO Arms, in the 4000 or 5000 version to match your holes.
• You own a 3×3 rack with 5/8 inch holes from another brand: Bells of Steel Hydra Lever Arms, after you confirm true 3×3 inch uprights.
• You own a folding rack: the PRx Halo Arms for PRx Profile racks, since they hang on the wall when you fold the rack.
• You train on an all-in-one trainer: Force USA Jammer Arms for G and C Series, or the RitFit LAM1 for the M1 PRO.
• You want the longest warranty: Bells of Steel (limited lifetime) or Force USA (lifetime frame, 2-year parts).
• Your rack cannot be bolted down: skip outside-mounted jammer arms. Look at a landmine attachment instead, which loads the bar into the floor.

Jammer arms vs a landmine attachment

Both give you an arcing press, but they work differently. A landmine holds one end of a barbell at the base of the rack, so the load pushes down and back into the frame and the floor. Jammer arms pivot from the upright at chest or hip height and swing out in front, so the load pulls the rack forward, which is why Titan and Bells of Steel tie outside mounting to a bolted rack. A landmine costs less and fits almost any rack. Jammer arms give you two independent arms, fixed handles and a smoother, machine-like path, plus rows, shrugs and squats. Many lifters end up owning both. Our best landmine attachment guide covers that side, and if you want dips from the same rack, see our best dip attachment for squat rack ranking.

Buying checklist: measure before you buy

• Upright size: measure the tube. 2×2, 2×3, 2.3×2.3 and 3×3 inches all appear on this list, and a jammer arm bracket made for one will not fit another.
• Hole size and spacing: 5/8 inch or 1 inch holes, and the spacing between them. REP, Bells of Steel, PRx and Force USA each sell separate versions by hole size, and Mikolo lists 3.94 inches between its two mounting pins.
• Rack model and year: Titan T-3 arms do not fit T-3 racks bought before October 2021. Mikolo, RitFit, Force USA and Major Fitness list only their own racks or trainers.
• Weight capacity: listed figures run from 260 lb static (RitFit) to 600 lb per arm (Titan, Mikolo). Compare it to the heaviest load you will put on a single arm, not both.
• Footprint in front of the rack: arm lengths run from 31.5 inches (RitFit) to 42 inches (REP), and REP lists 30.87 inches of width with horn and handle. Add your own standing room, and leave clear space for the plates at the end of the arc.
• Height of the arc: add the arm length to the height of the pivot to see the highest point the end of the arm can reach in a press. Check that against your ceiling, lights and garage door track.
• Anchoring: bolt the rack to the floor or a platform if the arms mount outside. Titan recommends it for all its lever arms, and Bells of Steel requires it for outside mounting.
• Rack depth for storage: Bells of Steel arms tuck inside racks at least 43 inches deep, and add 4.5 inches to the front when stored outside.
• Sleeve size: Titan uses 50 mm sleeves, REP a 2 inch horn and Bells of Steel 48 mm. All take Olympic plates, but plan your collars, since REP says its standard spring clips are too big for its horns.
• Warranty: from 1 year (Titan) to limited lifetime (Bells of Steel).

Setting up jammer arms safely

Seat each bracket fully, push the pins all the way through and check them before every session. Start with an empty arm to learn the path, then add plates evenly in small steps. Keep the rack bolted down, or at least do not use outside-mounted arms on a rack that rocks with an empty bar. Load and unload plates with the arm resting low or locked, and keep your feet out of the path of the plates at the bottom of the arc.

How we ranked these jammer arms

We compared and ranked jammer arms using the makers’ published specifications and product pages, read in October 2026. We weighted how widely each set fits, listed capacity, steel and tube size, arm length and footprint, adjustability and warranty, because those decide whether a set works safely on a real home rack. We did not use these products ourselves. Where a product page does not give a number, the table says so instead of guessing.

Frequently asked questions

What are jammer arms used for?

Jammer arms are plate-loaded arms that pivot from a power rack, so you can press, row, shrug, squat and lunge on a fixed arc. They are popular for jammer presses, standing chest and shoulder presses and single-arm work, and some sets, like the REP ISO Arms and Mikolo arms, lock in place for dips and pull-ups.

Are jammer arms worth it for a home gym?

Yes, if you already own a sturdy rack you can bolt down. They add a press and row machine with no new footprint for the base. They are less worth it on a light or unanchored rack, where a landmine attachment is safer and cheaper.

What is the difference between jammer arms and lever arms?

Nothing practical. Jammer arms is the common name, and makers call the same plate-loaded pivoting arms lever arms (Titan, Bells of Steel, Mikolo, RitFit), ISO Arms (REP) or Halo Arms (PRx).

Do jammer arms need the rack bolted down?

For outside-mounted arms, yes. Titan recommends using its lever arms only on a bolted-down rack, and Bells of Steel says the rack must be bolted down when its arms are installed on the outside of the uprights.

How much weight can jammer arms hold?

In this comparison, listed capacities run from 260 lb static for the RitFit LAM1 to 600 lb per arm for the Titan T-3, Titan X-3 and Mikolo arms. Bells of Steel lists 500 lb, PRx 220 lb per arm, and REP says seven 45 lb iron plates fit on each ISO Arm.

Will jammer arms fit any power rack?

No. Each set is made for one upright size and hole size, and most are made for one brand’s rack. Measure your upright (2×2, 2×3, 2.3 or 3×3 inches) and hole (5/8 or 1 inch), then buy the version made for them.

Are jammer arms better than a landmine?

They do different jobs. A landmine is cheaper and loads into the floor, so it is safer on an unbolted rack. Jammer arms give two independent arms, fixed handles and more exercises, but they need a rack that is anchored.

How much space do jammer arms need?

Plan for the arm length plus your standing room in front of the rack. Arm lengths in this comparison run from 31.5 inches to 42 inches. When stored, Bells of Steel arms add 4.5 inches to the front of the rack, and PRx Halo Arms hang on included wall storage.

Bottom line

The best jammer arms are the ones made for your exact rack. On a Titan T-3, buy the T-3 Series Adjustable Lever Arms; on a Titan X-3, the X-3 version; on a REP 4000 or 5000 Series rack, the ISO Arms; on a matching 2.3 inch or 3×3 inch rack, the Bells of Steel Lever Arms; on a PRx folding rack, the Halo Arms; and on a Force USA or RitFit trainer, that brand’s own arms. Measure your upright and hole size, check the listed capacity per arm, leave room for a long arm in front of the rack and bolt the rack down before you load it.
