**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

• Bolts to your 5x4.75" (5x120.65) hub so you can run 5x5.5" (5x139.7) wheels
• CNC machined from 6061 T6 billet aluminum
• New wheel studs included
• Fits many GM applications, including Camaro, Corvette, Firebird, El Camino, and the other models listed above
• Sold in pairs, with free US shipping

Mount each adapter to a clean hub face and torque it fully before the wheel goes on the adapter studs. Use the values in our torque reference chart, tighten in a star pattern, and re-torque all hardware after 50 to 100 miles.

Common questions

Which pattern is my car and which is the wheel?
The 5x4.75" (5x120.65) side bolts to your vehicle hub, and the 5x5.5" (5x139.7) side is what your wheels bolt to. If your hub is 5x5.5 and the wheels are 5x4.75, you need the opposite adapter, not this one.

Are wheel adapters safe?
Yes, with a proper install. Make sure the adapter seats flat on the hub, torque every nut to spec, confirm full stud engagement in each lug, and re-torque after the first 50 to 100 miles. Done that way, adapters are a reliable way to change bolt patterns.
