Cometic GM 3.2/3.8/4.1/4.8L Inline 6 3.8/4.3L V6 Chevy Gen1 SB V8 Silicone Rear Main Seal-2 Piece

This product is a two-piece rear main seal kit made from silicone. It's designed to replace the seal found in many GM inline 6-cylinder engines, as well as V6 and small block V8 engines from Chevrolet. This seal is crucial for preventing oil from leaking out of the engine where the crankshaft exits the block.

Cometic builds this seal to meet or exceed original equipment manufacturer quality standards. The silicone material offers good flexibility and resistance to oil and heat, which helps ensure a long service life. Because it's a two-piece design, installation is generally more straightforward than a one-piece seal, as you don't need to remove the crankshaft to replace it.

This seal fits a wide variety of GM vehicles from the early 1980s through the mid-1980s, including popular models like the Chevrolet C/K series trucks and the Chevrolet Camaro.
