Front Crank Seal SBC

The Front Crank Seal SBC by Peterson Fluid is a crucial component designed specifically for small-block Chevrolet engines, ideal for restoration, rebuilds, or performance modifications. This seal is strategically positioned at the front of the crankshaft to prevent oil leakage, ensuring the engine operates efficiently and protecting the engine bay from costly oil seepage.

Precision-manufactured to fit the specific bore diameter and crankshaft journal of small-block Chevrolet platforms, this front crank seal is engineered to resist blow-by and maintain positive crankcase pressure. Its compact design measures 3.9 x 0.85 x 3.95 inches and integrates seamlessly with OEM and aftermarket timing covers. The seal is made from a high-temperature elastomer, ensuring durability under sustained RPM and temperature cycling.

Engine builders and mechanics trust Peterson Fluid seals for their reliability across various SBC applications, including naturally aspirated, supercharged, and turbocharged setups. Installation requires the removal of the timing cover and damper, making it an opportune time to inspect and refresh all front-end sealing surfaces. This seal is compatible with many small-block Chevrolet configurations, enhancing the performance and longevity of your engine.
