Expert Buying Guide for 1994 GMC Safari Cargo
For your 1994 GMC Safari Cargo, the 5x127 bolt pattern and 78.1mm center bore are critical. Aftermarket wheels often have a larger bore; use hub-centric rings to avoid vibration. The 0mm offset is sensitive; deviations affect handling and tire clearance. Always verify lug nut thread pitch (1/2 20) and seat type (conical or ball seat) to prevent loosening. Cross-compatible wheels from 1992–2002 Safari Cargo models fit directly. Avoid wheels from 2003–2005 (6x139.7 pattern).

Refer to your owner's manual for exact specs, but always tighten the 1/2 20 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
Why is matching the 78.1mm center bore important for the 1994 Safari Cargo?
The 78.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
