Fel-Pro BS40529 is a rear main seal gasket set for the crankshaft seal area on select Chevy and GMC 6.2L diesel V8 applications from 1982-1991. The 2-piece rubber seal helps stop oil loss at the rear of the engine, a common repair point on stock truck, SUV, van, and step van drivetrains, while its application-specific design supports an OEM-style fit for standard service work.

• 2-piece rubber rear main seal construction is designed for the rear engine crankshaft sealing surface.
• Application-specific materials and shape are made to meet or exceed OEM specifications for standard repair use.
• Designed to seal even when the mating surface is less than perfect, helping address oil leaks without race-only hardware.
• Package dimensions are 23 in. x 4 in. x .300 in., with an approximate weight of .300 lb.
