Ford Racing 7.3L Gas Rear Main Seal Retainer Kit

If you're working on a 7.3L gas engine build or rebuild for your 2020-2024 Ford F-250 Super Duty, this rear main seal retainer kit from Ford Racing is what you'll need. This kit is designed to replace the main seal retainer and the rear main seal itself, which is crucial for preventing oil leaks from the back of your engine where the crankshaft meets the transmission.

This kit includes all the necessary components for a complete replacement: the rear main seal retainer, the main seal itself, and the retainer gasket. These are all OE production parts, meaning they meet the same specifications as the original equipment your truck came with. Using new, correct-fitting parts here is important for ensuring a solid seal and preventing oil from getting where it shouldn't.
