SBC Jesel Crank Seal

The SBC Jesel Crank Seal from Cometic Gaskets is an essential sealing component designed specifically for small-block Chevrolet (SBC) engines that have undergone high-performance modifications. This crankshaft seal is crucial for preventing oil leakage at the front of the crankshaft, a frequent failure point in boosted or heavily modified SBC builds. Whether you're working on a street machine, race engine, or vintage performance platform, a reliable crank seal is vital for maintaining bearing protection and preventing catastrophic oil loss.

Manufactured using advanced elastomer compounds and precise machining, the SBC Jesel Crank Seal ensures a dependable dynamic seal around the rotating crankshaft. It is engineered to withstand elevated oil temperatures and pressure cycles typical in forced-induction and high-RPM applications, where standard seals may fail prematurely. The compact design allows for straightforward installation during crankshaft service, front cover assembly, or complete engine rebuilds without extensive modifications to surrounding components.

Engine builders and mechanics working on SBC platforms—from carbureted stroker builds to modern LS hybrid conversions—trust Cometic Gaskets for OEM-quality sealing solutions. This crank seal is a direct fit for Jesel-equipped small-block engines, making it a reliable choice for those looking to enhance performance and maintain engine integrity.
