ISOLATOR Carriage Shims are precision spacers designed to eliminate gaps and wobble between your ISOLATOR carriage and different rack uprights. Since manufacturers build racks at slightly different sizes, these shims bridge the fit inconsistencies and deliver a tight, stable connection.
The shims install behind the plastic pressure plate on your carriage, taking up excess space without modifying your equipment. Available in 1mm and 2mm thicknesses, they allow you to achieve a custom fit regardless of your rack's tolerances. For gaps larger than 2mm, longer hardware is included to accommodate up to 5mm of total shim thickness per side.
Easy Installation
Simply place shims behind the plastic pressure plate. No drilling, cutting, or permanent modifications needed.
Stackable Design
Mix and match 1mm and 2mm sizes to dial in your exact gap. Longer bolts included for stacks up to 5mm per side.
Measure your gap first, then order the appropriate shim size for a rock-solid carriage fit.
ISOLATOR Carriage Shims are designed to work with ISOLATOR carriages on various rack platforms to address manufacturing tolerance gaps.
- Works with: ISOLATOR carriage on REP Fitness PR-4000, PR-5000, and compatible racks
- Also works with: ISOLATOR with Ares attachment, 2.3 x 2.3 racks, and other similarly-sized uprights
- Installation point: Behind plastic pressure plate on carriage
Shims are sold individually per size (not as pairs). Account for both left and right carriage sides when determining quantity needed.
- Available Thicknesses: 1mm ($4.00) and 2mm ($5.00)
- Maximum Stack Per Side: Up to 5mm total shim thickness (with longer bolts included for stacks exceeding 2mm)
- Standard Hardware Capacity: Current fasteners support up to 2mm thickness
- Extended Hardware: Longer screws provided for 3mm, 4mm, and 5mm configurations
- Pricing Model: Per individual shim, not per pair
Measure your carriage-to-upright gap and purchase shims accordingly for each side of your setup. Mix sizes as needed to reach your target thickness.
Why do I need carriage shims?
Different rack manufacturers build their uprights at slightly different sizes. These tolerance differences can create a gap between your ISOLATOR carriage and the upright, leading to shake or wobble during use. Shims fill that gap and deliver a rock-solid connection.
How do I know what thickness shim I need?
Measure the gap between your ISOLATOR carriage and the rack upright. If the gap is up to 1mm, use a 1mm shim. If it's 1mm to 2mm, use a 2mm shim. For larger gaps, you can stack shims (1mm + 2mm, or multiple 2mm shims) up to 5mm per side.
How do I install the shims?
Simply place the shim behind the plastic pressure plate on your carriage before fastening it to the upright. The existing hardware works for shims up to 2mm thick. For stacks exceeding 2mm, use the longer bolts provided to safely accommodate the added thickness.
Do I need shims on both sides of my carriage?
Not necessarily. Some users apply shims to only one side, while others use them on both. It depends on your specific gap and rack configuration. Check your left and right carriage gaps independently and shim as needed for each side.
Are shims sold individually or in pairs?
Shims are sold individually, not as pairs. So if you need 1mm shims on both the left and right sides of your carriage, you'll purchase two 1mm shims (one for each side).
What if I need more than 2mm of shim on one side?
You can stack shims up to 5mm total per side. When your stack exceeds 2mm, longer bolts are included in the kit to ensure proper fastening and support of the added thickness.

- ZSZack S.Verified BuyerRated 5 out of 5 stars2 years agoNeeded this for Rep PR-5000 upright
The isolator came with two 1mm shims, however there was still a little play so I ordered two more 1mm shims. Now everything is nice and snug. Great product.
- TJTravis J.Verified BuyerRated 5 out of 5 stars2 years agoRep PR-4000
Added 1mm shims on each side sandwiched between the uhmw and original push plate. No more wobbling!
- JCJeff C.Verified BuyerRated 5 out of 5 stars1 year agoShims work great
Works well!
- WTWill T.Verified BuyerRated 5 out of 5 stars1 year agoFits nice
Make the carriage fit my REP PR-4000 very nice. Will be reconfiguring soon to give the carriage a permanent location.
