Keep your AP Racing / Lockheed calipers working properly by rebuilding with these genuine AP Racing piston seals!

The caliper dust seals are important on a street car that is neglected for years at a time; however, many professional race mechanics prefer not to use them. We offer the piston (fluid) seals separately for all common piston diameters used in AP Racing/Lockheed calipers. These seals are now being manufactured with a new, high-temperature material for longer service in racing conditions. Sold individually.

Note 1: These seals are for AP/Lockheed seal-in-bore calipers only. They do not fit AP Racing seal-on-piston calipers or any other brand of calipers. Brakes are a critical safety component. We strongly recommend against trying to use these seals in other brands of calipers, even if the nominal piston size is the same. The results of brake system failure can have devastating effects!

Note 2: AP/Lockheed designs these seals to be compressed to size when they are installed in the caliper bore. They will be slightly oversize when they are loose.
