Wheel Adapter 4 Lug 4 To 4 Lug 137 (Pair)
This type of adapter is used for 4 lug 4" (101.6mm) bolt pattern cars to fit 4 lug 137mm bolt pattern wheels. CNC machined billet aluminum. New wheel studs are included. These adapters can be used on the following cars, among others:
- Buick: Skyhawk (75-81)
- Chevy: Vega (71-81)
- Pontiac: Sunbird (76-81), Astre (75-77)
Our premium quality adapters ensures durability and strength. Price is for a pair (2 adapters).
**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 a 4x4" (4x101.6mm) hub
- Runs 4x137mm wheels on the outer face
- Changes the pattern from 4x101.6mm to 4x137mm
- Supplied in a pair
- Free US shipping
Mount each adapter against a clean, flat hub with full stud and thread engagement. Any factory studs that reach past the adapter face need to be trimmed so the wheel seats flush. Bring the hardware to your vehicle's factory specification with help from the torque reference chart, and re-torque once after 50 to 100 miles.
Common questions
Are wheel adapters safe?
They are when installed correctly: seated flush on a clean hub, fully engaged threads, torqued to spec, and re-checked after a short first drive. Confirm the fit against the vehicles listed in the description above.
What does this actually change?
Your hub stays 4x101.6mm, but the wheel now bolts to a 4x137mm face, letting you fit 4x137mm wheels.
