BBC Rear Main Seal PREM VITON 2 PC SEAL

The BBC Rear Main Seal PREM VITON 2 PC SEAL by FEL-PRO is a crucial component designed specifically for big-block Chevrolet engines. This seal is ideal for engine builds, rebuilds, or long-term maintenance, ensuring optimal performance and cleanliness by preventing oil leakage at the rear crankshaft exit point.

Constructed from premium Viton (FKM) elastomer, this two-piece seal is engineered to withstand extreme engine temperatures and harsh operating conditions. The design allows for easier installation without the need for full crankshaft removal in many applications, which can significantly reduce labor time while maintaining OEM sealing performance.

BBC enthusiasts, restoration shops, and professional mechanics trust FEL-PRO seals for their durability and consistency. This seal is particularly beneficial during engine rebuilds, especially for 427, 454, and 502 cubic-inch engines, accommodating slight variations in bearing clearances and crankshaft runout common in vintage or high-mileage engines.
