3x3 Lever Arm tubes NOT included

You must already own or purchase the arms separately from the respective company



Turn your boring lever arms into the most versatile piece of equipment in your home gym with our patent-pending 180-degree adapter mounts!

This adapter kit replaces the existing upper mount with a new adjustable trolley that allows you to easily set the starting position making them extremely quick and convenient to set up.

The 180° adjustability allows you to set the starting angle of the lever arm so you can perform endless new exercises such as flat presses, incline presses, decline presses, hammer presses, shoulder presses, rows, calf raises, leg curls, leg extensions, various squats, hip thrusts, and several other exercises. 

Additionally, the adjusting pin can also be inserted through the bracket and tube to securely lock the arm into position for pull-ups, dips, bodyweight rows, or out-of-the-way storage. 



This adapter kit is specifically built to only be compatible with Rep Fitness 3x3 lever arms for both 5/8” and 1” holesplease ensure you are selecting the correct kit before ordering.

When selecting the hole size, select the size that matches your rack. 

The 180° outer holes align with the existing holes in the lever arm tube.

The inner 180° holes are designed to align with the existing lock-out hole on the Rep lever arms.

The adjusting pin is 5/8” for both the 1” and 5/8” versions. This allows the 1” version to still have 15 adjustable increments with the included 1” to 5/8” hole adapter.

Our trolleys will work on ALL 3” x 3” racks with 5/8” or 1” alternating holes. 

This version will NOT work on 2" x 3" racks.

  • Works with all 3" x 3" racks (including metric 75mm x 75mm)
  • 5/8" and 1" versions are available

  • Spring-Loaded Adjusting Pin for easy up and down adjustments

NOT Included

  • Hitch pins NOT included, must be purchased separately (4.5” minimum length required)
  • Adapters ONLY, 3" x 3" tubes are NOT included



  • NEVER use for dropped weights or as a dynamic spotter arm/device! Damage to your squat rack upright will occur from dropping weight. The adjusting pin and brackets are ONLY meant for supporting static loads and controlled stops at the end of a repetition.
  • DO NOT exceed 250 lbs static load per individual arm when supported by the adjusting pin. When the adjusting pin is not in use, the load rating is the same as the original manufacturer’s specs. Failure to follow this will result in a damaged lever arm tube.
  • ONLY use this attachment on squat racks that are properly anchored to the floor or wall per the original manufacturer's instructions as tipping due to the extended loads can occur. Similar to spotter arms when used outside the rack.
  • ALWAYS use an additional hitch pin inserted laterally through both sides of the original bracket and the squat rack upright post thus acting as a locking cross pin. This allows the additional forces from the extended arms to be supported by the inserted hitch pin and not the roller bolts.
  • NOT recommended for commercial facilities or applications

Great ISO arm upgrade!

I held off on ordering my ISO arms until I got word from Britton that my order was on the way. It took me about 90 minutes to install the Vendetta and ISO arm setup on my REP rack. The digital instructions were very straightforward. I ended up using all the shims on my rack bc Rep is metric.

The adaptors function better than expected. I'm 6'1" 250lb and they slide up and down the uprights with minimal effort. The process only becomes slightly awkward when I'm moving them from the floor to very top position for storage. The weight of the arms coupled with the 93" uprights makes it such that I raise the setup to my chest level, lock it in place, then readjust my grip to raise it to the top hole for storage. As I mentioned before, I don't have a comparison, but I'm guessing this process is lightyears better than the alternative.

I've seen online where people "hold" their lever arms in position with chains or spotter arms. Don't waste your time. Even if it was safe, the time it would take for those adjustments would make it not practical. I can switch movements or fine tune my setup in seconds versus minutes. I use them each time that I'm in my gym. Worth every penny!

Game changer

I tried for a year to purchase but it was always sold out . It was worth the wait. When the package arrived it was nicely packed. The instructions were clear and easy to navigate. The entire set up took an hour. Overall very happy with the results

Works perfectly

100% recommend. The Vendetta attachment is the best upgrade you can get for jammer arms. Also recommend going the extra mile for the GymPin Kaizen arm adapters as they pair perfectly with the Vendetta attachment. If you're going to spend the money on jammer arms, go all the way for the aftermarket upgrades.

Love these!

Spend the money....well worth it! Exceptional quality and fits my REP rack perfectly. Smooth as butter.
