It is very important that all retainer clips be removed before installing spacers or adaptors. Surface of rotor or drum must be cleaned. All mud, dirt, rust and or scaling must be removed before spacer or adaptor can be installed. Failure to follow instructions may not allow spacer or adaptor to be properly tightened.

Step 1. Remove tire using proper procedures called out in the jeep service manual.

Step 2. Remove any retainer clips from the mating surface of the drums or rotors.

Step 3. Clean wheel studs with a wire brush. Apply a quality thread lock to axle wheel studs.

Step 4. Place spacer or adaptor onto factory wheel studs. Thread supplied lug nuts with tapered end oriented toward spacer or adaptor. Tighten lug nuts in a criss-cross pattern. Set the torque to 85-100 Ft-Lbs. It will help to have another person holding the brake pedal when tightening.

Step 5. Clean and remove any dirt, rust or scaling from mating surface of road wheel. Reinstall tire to spacer or adaptor with factory lug nuts. Tighten to factory specications.


Attach spacer or adaptor using supplied lug nuts only. Make sure axle studs clear spacer or adaptor and allow full engagementof lug nut threads. NEVER DOUBLE STACK wheel spacer or adaptors. Serious injury or death may occur if warning is ignored.
