Clip-on Weights


Object Number: 315790  Size: SH

When dynamic balancing, locate the clip-on wheel balance weights on the inboard and outboard rim flanges at the positions specified by the wheel balancer.

When static balancing, locate the wheel balance weights on the inboard flange if only 28 grams (1 ounce) or less are called for; if more than 28 grams (1 ounce) are called for, split the weights as equally as possible between the inboard and outboard flanges.

Important: Use a nylon or plastic tipped hammer when installing coated wheel balance weights to minimize the possibility of damage to the polyester coat.

Special polyester-coated clip-on wheel balance weights are to be used to balance factory aluminum wheels. Coated weights reduce the potential for corrosion and damage to the aluminum wheel. These weights are designated to fit over the thicker inboard and outboard rim flanges of aluminum wheels. Coated wheel balance weight series AW (1) is used on Corvette factory aluminum wheels.

Adhesive Weights

Adhesive wheel balance weights may also be used on aluminum wheels. Adhesive wheel balance weights are the primary type of weight used on magnesium wheels. Use the following procedure to install adhesive wheel balance weights.

  1. Determine the correct area(s) for placement of the wheel weight(s) on the wheel.
  2. Important: DO NOT sand any surface of the wheel as this will damage the clear coat finish.

  3. Thoroughly clean the designated balance weight attachment area(s) of any corrosion, overspray, dirt or any other foreign material.
  4. To ensure there is no remaining residue, wipe the balance weight attachment area(s) with a mixture of half isopropyl alcohol and half water. Use a clean cloth or paper towel.
  5. Dry the attachment area(s) with hot air until the wheel surface is warm to the touch.
  6. Warm the adhesive backing on the wheel balance weight(s) to room temperature.
  7. Remove the tape from the back of the weight(s); DO NOT touch the adhesive surface.
  8. Apply the wheel balance weight(s) and press on with hand pressure.
  9. Secure the wheel balance weight(s) with a 70 to 110 N (16 to 25 lb) force applied with a roller.
