CNC Machined Billet Aluminum | Includes Wheel Studs | Pair of 2
These precision-engineered wheel adapters are designed to convert a 4x4" (101.6mm) bolt pattern to a 4x100mm bolt pattern, allowing you to fit modern or aftermarket wheels onto classic vehicles. Ideal for restoring or modifying vintage models, these adapters make it easy to upgrade your wheels without changing the original hub setup.
Each adapter is CNC machined from high-strength billet aluminum for maximum durability, corrosion resistance, and a precise fit. The adapters come complete with new pre-installed wheel studs for a secure installation.
Buick: Skyhawk (1975–1981)
Chevrolet: Vega (1971–1981)
Pontiac: Sunbird (1976–1981), Astre (1975–1977)
Converts 4x4" (101.6mm) hub to 4x100mm wheel bolt pattern
Ideal for fitting modern 4x100 wheels on vintage 4x4” vehicles
CNC machined billet aluminum for strength and accuracy
Includes new wheel studs pre-installed
Improves wheel fitment flexibility and appearance
Sold as a pair (2 adapters)
Installation Note:
If your factory hub studs extend beyond the surface of the adapter and interfere with wheel mounting, you may need to shorten the OEM studs to ensure the wheels seat properly against the adapter. This is especially common with 1" thick adapters or thinner configurations.
