The FEL-PRO Rear Main Seal for BBM and Hemi engines is a vital component designed to prevent oil leakage at the crankshaft's rear position, where the engine block meets the transmission bell housing. This two-piece seal assembly is essential for anyone rebuilding a high-performance Hemi or restoring a classic big-block muscle car, as it helps prevent catastrophic oil loss and engine damage.
The design of this seal accommodates the natural shaft runout and block surface variation common in Hemi and big-block applications, ensuring a consistent contact line that prevents bypass leakage. It is engineered to withstand the extreme temperature and pressure conditions at the crankshaft's journal, making it a reliable choice for various applications.
Mechanics and engine builders working on Dodge, Chrysler, and Mopar platforms specify this seal for both stock restorations and modified builds. Its compact profile makes it easy to fit into tight engine bay spaces during installation or service, ensuring that it meets the needs of both professional and DIY mechanics.
