Cometic Ford 351W/351C 335 Series V8 / 351W Windsor V8 Viton Rear Main Seal 2 piece

This Cometic rear main seal is made from Viton, a material known for its excellent resistance to heat and oil, making it a solid choice for your Ford 351 Windsor or 351 Cleveland engine. It’s a two-piece seal, designed to replace the original seal in a variety of Ford vehicles from the late 60s through the mid-80s, including models like the Ford F-150, Bronco, and LTD.

Cometic builds these seals to meet or exceed OEM quality standards. This means you can expect a reliable seal that holds up well in the demanding environment of the engine's crankshaft area. Viton is a great material for this application because it can handle the high temperatures and constant contact with engine oil without breaking down, which helps prevent leaks and keeps your engine running smoothly.
