Cometic Gaskets Rear Main Seal for Ford 351C/351M 335 Series V8, 351W Windsor V8, 2 Piece - C5689

Ford 351C/351M 335 Series V8 & 351W Windsor V8 Rear Main Seal

If you’re diving into the world of classic Fords, you know the importance of a solid rear main seal. This 2-piece Viton rear main seal is a game changer for anyone working on their 351C, 351M, or Windsor V8. I’ve been there, wrestling with leaks and oil drips, and trust me, this seal can save you a whole lot of headaches.

Why Viton? It’s tough stuff. This material holds up against the heat and oil that comes with high-performance engines. You want something that’s going to last, especially if you’re pushing your ride to its limits. The seal fits snugly in the rear position, ensuring that your engine stays clean and dry, so you can focus on enjoying the drive rather than worrying about your garage floor.

Fitment

This seal isn’t just for one model; it’s compatible with a range of classic Fords. Whether you’ve got a 1978-1983 Ford Bronco or a 1969-1973 Ford Mustang, you’re in luck. It also fits various trucks like the F-150, F-250, and F-350 from '77 to '83. And let’s not forget the Mercury Cougar and Fairlane—it’s got you covered there too.

Technical Details

  • Prop 65 compliant, so you can install it with peace of mind.
  • Designed specifically for the 351C/351M and Windsor V8 engines.

In short, if you’re looking to keep your classic Ford running smoothly, this rear main seal is a must-have. It’s straightforward to install, and once it’s in, you can hit the road knowing you’ve got a reliable seal keeping everything in check. No more oil leaks, just the open road ahead.
