BOP One-Piece Rear Main Seal

 

 

 
Buick One-Piece Viton ® Rear Main Seals

The BOP Engineering One-piece rear mail seal is the most advanced rear main seal on the market. This revolutionary design features a double lip design to provide more protection against leakage as well as outstanding vacuum numbers. The seal has a flexible steel core which is split in one location where the seal is to be sectioned and then spiraled around the crank. Note that this seal is not a “direct fit” for the Buick V8 which is why a section must be removed, but has been used with great success. Note that the crankshaft must be removed to install this seal.
