SUBJECT:
INFORMATION ON COATED BALANCE WEIGHT USAGE FOR ALUMINUM WHEELS

MODELS AFFECTED:
ALL 1983-1992 MODELS

Wheel balance weights are now available through GM Dealer Equipment at a very attractive price. These are original equipment weights that will assure best fit to GM original equipment wheels. The AW series and MC series of polyester coated weights are offered for aluminum wheels. IT IS IMPERATIVE THAT COATED WEIGHTS BE USED ON ALUMINUM WHEELS TO PREVENT COSMETIC DAMAGE TO THE WHEEL. A plastic tipped hammer should also be used to prevent damage to the weight's coating during installation.

Uncoated XT type weights are also offered for passenger car steel wheels.





Usage of AW and MC weights on aluminum wheels by GM vehicle line is shown in the illustration. Using the incorrect type of weights will result in improper fit, and such weights may fall off the wheel. This information should be posted near the wheel balancer to aid in weight selection.
