Fel-Pro 2901
Performance rear main seal for Ford Small Block 260 / 289 / 302 engines with a two-piece rear seal design. The fluoroelastomer construction is intended for more demanding use than a standard rubber seal, especially in rebuilt or performance-oriented engines.
Application / fitment
Designed for Ford 260 / 289 / 302 Windsor engines with a 2-piece rear main seal, mainly classic Ford and Mercury applications from approximately 1962–1984. Do not use it in later 5.0 blocks built for a one-piece rear main seal.
- Ford 260 CID V8
- Ford 289 CID V8
- Ford 302 CID / 5.0 V8 with a two-piece rear main seal
- Rebuild, performance and restomod applications where the block uses the correct split-seal design
Before installation, verify block type, crankshaft sealing surface, seal lip direction and crankcase ventilation condition. On modified engines, excessive crankcase pressure can still cause leakage even with a new seal.
