Good To Know

Q: Do the seals come pre-installed on the backing plate? A: The seals are supplied loose; you press them into the plate and housing during reassembly just like the factory procedure.

Q: Will this kit work with aftermarket brake drums? A: Yes, as long as the drum mounts to the stock backing plate pattern—always verify the drum’s inner diameter matches the plate register.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
