Expert Buying Guide for 2003 GMC Savana 3500 Passenger
For your 2003 GMC Savana 3500 Passenger, the bolt pattern is 8x165.1mm with a center bore of 116.7mm. When selecting aftermarket wheels, ensure the center bore matches exactly or use hub-centric rings to prevent vibration and ensure proper load distribution.
