The SBC 350 Rear Main Seal from Peterson Fluid is an essential component for preventing oil leakage at the crankshaft exit point of small-block Chevy engines. This product is ideal for anyone rebuilding a classic 350 engine, restoring a performance build, or addressing a weeping seal on an existing engine. A quality rear main seal is crucial for maintaining engine reliability and cleanliness.
Engineered to contain pressurized oil and maintain crankcase integrity, this rear main seal is manufactured to OEM-equivalent specifications. It is designed to fit the SBC 350 crankshaft flange precisely, ensuring it can withstand sustained oil pressure without hardening or losing elasticity over time. The compact dimensions of 3.3 x 1.05 x 3.45 inches allow for a tight fit in the bell housing area, which is critical for preventing oil bypass.
SBC 350 owners installing a fresh crate motor or addressing a slow oil seep will find this seal compatible with standard SBC 350 crankshafts. It is suitable for both stock and modified engine applications, including those with Vortec heads and aftermarket stroker builds. Installation requires the removal of the transmission and flywheel, making it a task for both seasoned engine builders and DIY mechanics.
