**If the hub studs protrude outside the adapter and prevent the wheels to sit flush on the adapter plates, it is required to shorten the factory studs. It happens most often on 1" thick adapters.
Fitment and specs
- Bolt pattern: 5x4.75" (120.7mm) on both the hub side and the wheel side
- Same-pattern design, so it works as a wheel spacer that adds track width
- New 7/16" thread wheel studs and lug nuts included
- CNC machined billet aluminum
- Thickness options: 1", 1.25", 1.5", and 2"
- Sold as a pair (2 adapters)
Bolt each adapter to the hub first, then check that the factory studs do not stick out past the plate face. If they keep the wheel from sitting flush, which happens most often with the 1" thickness, the factory studs need to be shortened. Torque all hardware to spec using our torque reference chart and re-torque after 50 to 100 miles.
Common questions
My car is already 5x4.75. What does this adapter do for me?
Since the pattern is the same on both sides, this set works as a spacer. It moves each wheel outboard by the thickness you choose, adding track width and clearance for wider wheel and tire setups.
What thread are the included studs?
The new wheel studs are 7/16" thread, and matching lug nuts come in the kit, so you have fresh hardware for mounting your wheels to the adapters.
