Jammer arms and lever arms are popular power rack attachments for home gyms, as they can mimic multiple commercial gym machines in a small space. However, most traditional jammer arms have a limited range of motion, only able to rotate up and down along a vertical claim.
Some jammer arms manufacturers are working on allowing free motion in their jammer arms, as well as locking positions vertically and horizontally, allowing for a massive amount of versatility. Most solutions have been through the use of jammer arm adapters by companies like Vendetta and GymPin, but it’ll cost a bit of extra money and have a clunky DIY sort of feel.
PRx Performance has attempted a combination of all solutions in their Halo Arms. With 17 vertical locking positions and nine horizontal locking positions, the jammer arms also unlock to provide a free range of motion, allowing for plenty of fixed positions. But does the versatility match the price? Let’s find out in this PRx Halo Arms review.

- Adjustability
- Ergonomics
- Versatility

- Unlocks for multi-directional movement
- Option between multi-grip or straight handles
- Compatible with 5/8″ or 1” holes on 3×3″ uprights

Pros & Cons
Pros
- Very versatile
- Vertical and horizontal locking positions
- Compatible for 5/8" or 1” holes
- Choice of multi-grip or straight handles
Cons
- Expensive
- Not compatible with Profile Folding Racks

Bottom Line
The PRx Halo Arms are a unique pair of jammer arms compatible with 3-inch-by-3-inch uprights with 5/8-inch or 1-inch holes. With 17 vertical and 9 horizontal locking positions, the Halo Arms are extremely versatile; plus, the arms can be unlocked to provide multi-directional movement—although the movement will still stem from the fixed point on the power rack uprights.
A Quick Look at the PRx Halo Arms
Before the Halo Arms, to get fully articulated jammer arms, you’d have to apply myriad adapters and attachments to your lever arm attachments, which made a bit of a Frankenstein contraption at the end of the day.
PRx Performance tries to bring all those versatility and functionality solutions together in one piece of equipment with the Halo Arms. These unique American-made jammer arms combine vertical locking with horizontal locking positions to provide many starting points for your exercises. For example, if you’re looking to do an overhead press, you can lock the arms at shoulder height to start there instead of lifting the jammer arms from the uprights each time.
The Halo Arms can also be unlocked to allow a free range of motion so that during that same overhead press example, you can start wide and press the arms together, mimicking a dumbbell press. While it’s not a perfect one-to-one feel, this functionality brings a ton of versatility that before would take a lot of adapters and attachments to get.
Before You Buy
- The Halo Arms are currently on pre-order, with shipments beginning in September.
- You have a choice between multi-grip handles or a knurled straight handle.
- These arms are compatible with 3-inch-by-3-inch uprights with 5/8-inch or 1-inch holes.
- They’re not compatible with the PRx Profile folding racks, as they’re too heavy for wall-mounted racks. They’re made more for the PRx Build Limitless racks.
- PRx got in some hot water when these jammer arms were initially released, being accused of taking ideas from Vendetta and Kaizen DIY Gym and applying it to their arms, then patenting the lever arms. While it appears they’re now in talks of collaboration with the smaller companies, you can check out Coop’s reaction to the controversy in this Garage Gym Reviews video.

Are the PRx Halo Arms Worth It?
Coop doesn’t mince his words when asked how the PRx Halo Arms perform. “If you want the best of the best, these are them,” he says. There are slight things we’d like to see improved, but the Halo Arms outperform many jammer arms with their added functionality.
However, the price tag of $1,500 is a little tough to swallow. “It’s still on the verge of just being a little too much, especially for people on a budget,” adds Coop. He rates the value a 3.5 out of 5. There aren’t many jammer arms that come with this level of versatility, but you’ll have to decide if that’s worth your money.
The only similar pair of lever arms with the added functionality of horizontal and vertical locking positions built in are the Griffin Adjustable Lever Arms. While we haven’t tested these out yet, they are a bit easier on the wallet, costing just under $900—although it appears there are fewer locking positions available. Still, this may be an alternative if the PRx arms are too pricey for you.
Great for:
- People looking for rack accessories that can replicate gym machines
- Lifters wanting massive versatility in their jammer arms
- Anyone interested in the possibility of cable and pulley systems down the road
Not recommended for:
- Home gym users looking for budget-friendly equipment
- Those who own PRx Profile folding racks
- Anyone with a rack that lacks 3” x 3” uprights

Using the PRx Halo Arms
GGR founder Coop Mitchell has mixed feelings about jammer arms. He explains in his full video review, “I kind of fell out of love with jammer arm attachments for a bit, but I’ve found myself using them more and more. You have to get creative, and you need those features like horizontal and vertical locking positions to get the most out of them, but there’s a lot of potential in jammer arms.”
The PRx Halo Arms are close but not the perfect jammer arms. That said, Coop was able to use them for a lot of exercises, and we mean a lot. You name it, he did it: pull-ups, bench presses, seated presses, rows, and even deadlifts. The jammer arms can also be set vertically as uprights for barbell squats and other movements.
You can load the arms with Olympic bumper plates and weight plates; plus, the 17 vertical locking positions and nine horizontal positions create a ton of versatility, even within exercises. You can also press in a locked position for isolation exercises or unlock it to allow free movement during your workout.
The immense possibilities get the Halo Arms a rating of 5 out of 5 for versatility. The PRx arms would get a perfect score for adjustability as well, except the arms’ horizontal positions are a bit too far apart. “As is, there’s only a couple positions that feel somewhat comfortable to me for raises and presses,” Coop adds. “Some positions in between would really help in being able to do narrow-grip or wide-grip movements.”
There are still a ton of adjustments available, so Coop rates the adjustability a 4.5 out of 5.
Construction and Durability
There’s a lot of great design in the build of the PRx Halo Arms, earning the jammer arms a 4.5 out of 5. PRx always has a solid powder coat and the Halo Arms are no different, with a black powder coat covering the arms’ 11-gauge steel, and their Porsche grey on the side of the levers.
The arms can slide up and down the upright with knurled handles to guide the attachment. Another great feature is that the lever arms can fit two common hole sizes: 5/8 inches or 1 inch on a 3-inch-by-3-inch upright. This means if you want to upgrade your power rack, you have two options, regardless of what your current squat rack has.

There’s the potential for a cable and pulley system for the jammer arms to compete with rack functional trainers like the REP Ares 2.0, but the pulleys aren’t available yet. “They’re probably waiting to see interest,” Coop suggests.
The abundance of holes doesn’t just add versatility to your arms, but they also keep them lighter. At 60 pounds per arm, these are still hefty but not quite as heavy as other jammer arms in the market—like Rogue, for example. “I like that they didn’t overbuild the arms,” Coop adds. “The lighter weight can allow for lateral raises and some lighter movements.”
The PRx Halo Arms don’t come without some faults. For one, the two pop-pins provided are a bit underwhelming. “The pins don’t match and are pretty basic and have a joystick-like feel to them,” Coop adds. “I don’t want to feel like I’m playing a video game; I want to feel like I’m lifting weights. Add some knurling or make them magnetic.”
Also, one of the holes in our Halo Arms wasn’t cut to diameter when we tested them. “PRx is making these in-house, and their customer service is in-house,” Coops says, “so they’ll help you out if you run into an issue like this.”
Since this happened to us, we had to call it out.
Ergonomics
The PRx Halo Arms earn a 4 out of 5 for ergonomics, as there are quite a few features that make the jammer arms more convenient and easy to use, but Coop feels there were some missed opportunities.
You can guide the trolley with a knurled handle, which is a nice feature. Plus, the back of the trolley has an opening to see the upright number (if you have a Build Limitless rack). However, the numbers aren’t laser-cut or -etched onto the jammer arms. “These arms are made to be used as uprights, but without numbers, it’s going to be hard to line up J-cups or spotter arms,” Coop adds.
Another spot where numbers would have been a “nice-to-have” are the horizontal and vertical locking positions. The vertical positions have lines to mark the holes, but numbers would’ve been much more efficient than remembering which line you adjusted to.
Coop tested out the multi-grip handles, but PRx also has the option for straight, knurled handles. The multi-grip handles were OK, but the fixed handle positions might make some movements feel awkward. Coop recommends checking out Rorman Strength’s handles, which rotate on ball bearings and make for a more natural feel during movements.
PRx Halo Arms vs Rogue LT-1 50 Cal Trolley and Lever Arm Kit
Rogue Lever Arms
Rogue LT-1 50 Cal Trolley & Lever Arm Kit
Product Highlights
The Rogue LT-1 Trolley™ and Lever Arm Kit gives athletes the ability to quickly reconfigure a Monster rig or rack for a wide range of movements, without the need of a wrench or other tools. We’ve put years of research and refinement into this design, looking to create an optimal mechanism that can attach to an existing 3×3” upright and enable easy north/south adjustments with lock-in stability.
Pros & Cons
Pros
- The LT-1 50-Cal Trolley and Lever Arm Kit from Rogue is one their best engineered pieces of equipment that we’ve tested and reviewed. The quality is incredible.
- The adjustability of the lever/jammer arms greatly increases their versatility as well as their use.
- The handles on the trolley are knurled stainless steel bars that feel similar to Rogues barbells and are both easy and enjoyable to use.
- The trigger setup to allow for adjustability is the best we’ve used yet among adjustable jammer arms like the Sorinex Adjustable Jammer Arms.
- The set screws in the back of the trolley allow the system to sit flush with the uprights with little/if any side to side or forward and back movement during use. This is an important feature.
- The handles feature multiple handles for gripping.
- The weight horns on the handles are made of stainless steel and therefore won’t scar up easily and should look good for a long time, especially when compared to powder coating.
- There are a lot of movements that can be done with the lever arms like overhead presses, snatches, car deadlift, rows, and more.
Cons
- This is an expensive piece of kit and should only be seriously considered if you know you’ll get your use out of them.
- The arms don’t move as easily/smoothly as Sorinex’s due to tighter tolerances. Not a big deal, but not as convenient to use without much weight.
- At launch, there were many different attachments teased, however, after about a year since release, we’ve yet to see them come to market.
Bottom Line
The Rogue LT-1 50-Cal Trolley and Lever Arm Kit has been shown in our review to be a high quality and versatile piece of equipment for any home gym, however, it is expensive. We only recommend this to those that know they will use it as there are many other pieces of equipment that can be bought with the price of this one.
The Rogue LT-1 Trolley and Lever Arms are much more of a typical jammer arm without the added functionality of locking the arms in horizontal and vertical paths. With the lever arms starting at $1,170 by themselves, you’ll need to add about $700 worth of adapters to get the same level of functionality as the PRx Halo Arms, meaning the Rogue arms and adapters will be close to $2,000.
If you’re looking for this amount of versatility in jammer arms, Coop recommends the PRx Halo Arms. Both options are expensive, but the Halo arms have the functionality you want at a slightly cheaper price.

Final Verdict of Our PRx Halo Arms Review
The PRx Halo Arms are a nice pair of arm attachments for your home gym, especially if you’re looking for a way to incorporate machine training into your gym without having multiple machines in your gym space.
Are they the world’s most perfect jammer arms? They’re pretty good, but there’s a few items Coop would like to see improved upon, notably adding numbering along the horizontal and vertical locking positions. The horizontal positions could be smaller, to allow for slight angle adjustments, and the pop-pins could be upgraded to match the rest of the arms.
However, if you’re looking for the best jammer arms available, these are currently the top dog. It’s up to you to decide if the Halo Arms are worth the high price tag for your home gym.

PRx Halo Arms: FAQs
Are lever arms worth it in a home gym?
Many lever arms can mimic many gym machines, providing versatility to your home gym and saving a lot of space. With that said, the best jammer arms provide locking positions along the vertical or horizontal plane, which will offer the most versatility.
How are the PRx Halo Arms different?
Most jammer arms don’t allow for locked positions or free multidirectional movement; you’d have to purchase adapters for that kind of versatility. However, the PRx Halo Arms are unique lever arms that allow the jammer arms to be in fixed horizontal or vertical positions for a variety of uses. You’re also able to unlock the angles for multidirectional movement.
