Need to move your wheels out for a little extra space? This set of black hub-centric 1 inch (25 mm) wheel spacers from Rugged Ridge has a 120 mm bolt pattern and 64 mm center bore. The hub-centric construction ensures the wheel is precisely centered on the axle; minimizing stress on wheel studs; and eliminating the added road vibration common with non-hub-centric designs. Installing these spacers will help fit wider tires; giving your vehicle a wider track and improved stability. Constructed of double anodized extra thick 6061-T6 aluminum for long life and extra corrosion resistance. All hardware is grade-8 for extra strength.
