COATS Offset Truck Wheel Adapter Set for Reliable Tire Balancing
You're mid-shift, wheels are stacking up, and the last thing you need is to improvise an adapter that never quite fits. The COATS Offset Truck Wheel Adapter Set, 40mm ID takes that headache off the table. Ford, GM, or Chrysler, you get accurate balancing on your COATS balancer without the makeshift setups and guesswork that slow a busy line.
Clear markings on each adapter mean you switch between applications fast, not fumbling to figure out which piece goes where. The double-sided adapters and included backing plate cut the clutter and cover more truck lines from one compact kit. Fewer parts to hunt for. More wheels balanced per hour.
The value here is in the workflow. Once the kit is set up, you go straight from dismount to balance without walking back to the parts shelf for a one-off adapter. The tight shaft fit and backing plate steady heavier wheels so they spin true, which is where the valve index balancing feature earns its keep. Position the wheel, index the valve, and you're balancing off a reference point instead of eyeballing it. That's less rework on wheels that were never going to forgive a sloppy setup.
Buy this set from GSG and you're getting Coats' own accessory built for the balancers you already run, not a generic knockoff that fits close enough. We ship it free to the lower 48 and our team is on the line if you need to confirm fitment before you order.

Frequently Asked Questions
Will this adapter set fit my COATS balancer?
It's built for COATS balancers with a 40mm ID shaft. If your balancer uses that shaft, all 3 pieces mount directly, no spacers or improvised hardware needed. Not sure what your shaft measures? Give us a call before ordering and we'll help you confirm.
Which truck brands does this cover?
The two double-sided adapter rings cover Ford and GM/Chrysler truck wheels, so one kit handles multiple truck lines without swapping to a different balancer or buying separate adapters.
What comes in the set?
You get 1 backing plate and 2 double-sided adapter rings, one for Ford and one for GM/Chrysler. Three pieces total, packed compact enough to store without eating up bench space.
Does it work for heavy truck wheels?
Yes. It's suited for light and medium-duty truck wheels, mounting on the 40mm ID shaft of your COATS balancer. The included backing plate stabilizes heavier wheels on that shaft for smoother, more consistent balancing runs.
How is this different from a makeshift adapter setup?
A makeshift rig usually means one improvised adapter per truck line. This kit replaces that with 2 double-sided rings covering 3 brands (Ford, GM, Chrysler), plus a valve index balancing feature that positions the wheel off a fixed reference point every time. That's what cuts the rework you get from eyeballed setups.
