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.
