Wheel Adapter 4x4 To 4x156 (Pair)
This type of adapter is used for 4 lug 4" (101.6mm) bolt pattern cars to fit 4 lug 156mm 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
- Hub side: 4x4" (4x101.6mm)
- Wheel side: 4x156mm
- Keeps a 4-lug count while changing the bolt circle
- Sold in pairs
Each adapter bolts to your 4x4" (4x101.6mm) hub and gives you a 4x156mm wheel face, so you can fit wheels drilled for the wider circle. Seat them flat on a clean hub, torque to your vehicle's factory specification, and re-torque after 50 to 100 miles. Follow the torque reference chart for the sequence. Trim any studs that reach past the adapter face so the wheel seats flush. Free US shipping.
Common questions
Are wheel adapters safe?
Yes, when they seat flat against a clean hub, are torqued to spec, re-torqued after a short first drive, and keep full stud and thread engagement.
Both sides are 4-lug, so what does this change?
The bolt circle. It moves you from a 4x4" (4x101.6mm) hub to a 4x156mm wheel pattern rather than adding lugs.
