This type of adapter is used for 5 lug 4.75" (120.7mm)bolt pattern cars to fit 5 lug 4.5" (114.3mm) wheels. CNC machined 6061 T6 billet aluminum and thickness options are 1", 1.25", 1.5" and 2". New wheel studs are included. These adapters can be used on the following cars, among others:
Vehicle fitment
- Cadillac: Eldorado (1979-1985), Seville (1976, 1980-1985)
- Chevrolet: Camaro (1982-2002), Corvette (1968-1982, 1984-1996), Corvette ZR1 (1991-2019), Impala (1977-1985, not the wagon or HD models), Caprice coupe and sedan (1977, 1984)
- Chevrolet truck and SUV: El Camino (1964-1987), S10 (1982-2004), S10 Blazer (1983-1994)
- Pontiac: Grand Prix (1969-1987), GTO (1964-1974), LeMans (1964-1981), Firebird (1967-1992), Trans Am (1969-1982, 1992-1993)
- Measure your hub's center pilot, front and rear, and confirm it passes through the adapter's 74.1mm center bore; the 1993 Trans Am has a 74.1mm rear hub pilot, so check that one first. Hub-side lug nuts are bought separately: use nuts that match your hub studs' thread (7/16"-20 on, for example, the Pontiac GTO 1964-1974, LeMans 1964-1981, Grand Prix 1969-1981 and Trans Am 1969-1981) and the adapter's seat, and confirm your hub studs pass through the adapter's hub-side holes before ordering.
Our premium quality adapters ensures durability and strength. Price is for a pair (2 pieces).
**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 5x4.75" (5x120.65mm) vehicle hub
- Lets you mount 5x4.5" (5x114.3mm) bolt pattern wheels
- Thickness options: 1", 1.25", 1.5", and 2"
- CNC machined 6061 T6 billet aluminum
- New wheel studs included
- Sold as a pair (2 adapters) with free US shipping
Clean the hub face so the adapter seats flat, fasten it to the vehicle studs, then mount the wheel on the new studs. Torque all hardware to spec using our torque reference chart and re-torque after 50 to 100 miles.
Common questions
Which thickness should I choose?
Pick the thinnest option that lets your 5x4.5" wheel clear the brakes and suspension. Each step up in thickness pushes the wheel further out, so measure the clearance you actually need between the 1", 1.25", 1.5", and 2" options rather than defaulting to the thickest one.
Are wheel adapters safe?
Yes, when installed correctly. The adapter must sit flat against a clean hub, all hardware torqued to spec and re-torqued after 50 to 100 miles, and the lug nuts need full thread engagement on the studs. These are CNC machined from 6061 T6 billet aluminum for strength and durability.
