Vehicles with cast aluminum wheels use a coated clip on-wheel weight. The coating has recently changed from nylon to polyester, giving a more natural
appearance that more closely matches the wheel. Coated balance weights are used on both the inboard and outboard rim flanges. They will not discolor,
corrode or damage the appearance of the wheel as may have been the case in the past with uncoated clip on weights. These coated weights will fit most
GM cast aluminum wheels.
There are two types of coated wheel weights available to fit the GM vehicles. Both types of weights are available from GMSPO in 1/4 ounce increments.
Refer to the information below to determine which type weight is correct for the vehicle.
Dealers should make sure they have a supply of both type weights for balancing GM aluminum wheels.
When installing the coated weights, care must be taken so that the coating does not crack. It is recommended that a Teflon tipped hammer be used, such
as 85403 Nicholson Industrial Hammer(R), their part number CAS 3340551, available through the Charles Strelinger Company, Warren, MI
(313-268-4100), or equivalent.
