Wheel Adapters for Buick Grand National

Wheel Adapters for the Buick Grand National

Every Buick Grand National left the factory on a 5x4.75" (5x120.65mm) bolt pattern, and these adapters bolt to that hub so you can run a wheel drilled for a different pattern. Pick the adapter that matches the wheels you want, torque to spec, and go. Each listing ships as a pair (enough for one axle) and includes the hardware to mount both the adapter to the hub and the wheel to the adapter.

Buick Grand National bolt pattern by year & common questions

Buick Grand National bolt pattern by year

  • 1982-1987 Buick Grand National (G-body), 5x4.75" (5x120.65mm) ✔ these adapters fit

The Grand National badge was only built on the 1982-1987 rear-drive Regal G-body, and every one of those years shares the 5x4.75" pattern, so if you have a genuine Grand National, these adapters are the right hub side. Do not use these on later GM cars that reused the Regal name on a different (front-drive) platform; those are a different pattern and these will not bolt up. Years are a guide only, confirm your exact year and trim before ordering, and the 5x4.75" pattern is your safety check.

Convert your 5x4.75" hub to:

  • 5x4.75" → 5x4.75" (5x120.65mm), spacer-style, same pattern for offset/clearance
  • 5x4.75" → 5x4.5" (5x114.3mm)
  • 5x4.75" → 5x120mm
  • 5x4.75" → 5x5" (5x127mm)
  • 5x4.75" → 5x5.5" (5x139.7mm)
  • 5x4.75" → 6x5.5" (6x139.7mm), hub centric, 2" thickness
  • 5x4.75" → 8x6.5" (8x165.1mm), 2" thickness

All sold in pairs (one axle). Buy two pairs for a full set of four.

Common questions

What bolt pattern does the Buick Grand National use?
All 1982-1987 Grand Nationals use a 5x4.75" (5x120.65mm) bolt pattern. That is the "from" side these adapters attach to.

Which adapter do I need?
Start with your hub (5x4.75") and match the "to" side to the bolt pattern of the wheels you want to run, for example, 5x4.75" to 5x5" if your new wheels are drilled 5x127mm.

Do these fit every Regal?
No. They fit the 1982-1987 Grand National and its G-body siblings on the 5x4.75" pattern. Newer front-drive Regals use a different pattern and are not compatible.
