Seal Front Crank BBC

The Seal Front Crank BBC by Peterson Fluid is a precision front crankshaft seal designed specifically for big-block Chevrolet engines and high-performance applications. This OEM-quality seal is essential for anyone involved in rebuilding classic muscle cars, restoring vintage drag racers, or upgrading marine engines, as it effectively prevents costly coolant and oil leaks at the crankshaft hub.

Manufactured to tight tolerances, the Seal Front Crank BBC uses premium elastomer compounds that resist oil degradation, heat cycling, and abrasive particles, making it suitable for high-mileage and modified engines. Its dual-lip design creates a dynamic seal against the crankshaft journal, minimizing leakage while reducing friction and parasitic drag. The compact footprint ensures direct fitment without modification, making installation straightforward for those familiar with basic engine work.

Mechanics and engine builders trust Peterson Fluid seals for their reliability in street engines, racing platforms, and boat motors powered by big-block Chevrolet engines. This seal is ideal for anyone performing a full engine refresh or converting carbureted BBC power, ensuring engine longevity and performance reliability.
