This Rear Axle Seal Kit is designed for 64-65 Porsche 356C/SC cars with all-disc brakes. It includes a small o-ring, large o-ring, hardened steel shim, and the necessary cotter pin. Two kits are required per car. Our kit contains high-quality seals, o-rings, and the essential hardened flat washer. Unlike cheap VW kits with inferior parts and soft flat washers that may cause leaks and issues, our kit ensures a proper, long-lasting seal. Don't compromise on quality – get it right the first time with our Rear Axle Seal Kit.
