Cometic GM Gen V LT Oil Pan Gasket .018" OP888018AFM

The Gen-V LT family shipped without a factory oil pan gasket across the board. If you've pulled the pan on any of these engines, you already know what that means for teardown and reassembly.

Specifically for the GM Gen-V LT Small Block V8. It seats and clamps correctly with factory hardware across all L82, L83, L84, L86, L87, and L8B applications. Built to spec, no modifications required.

Gasket covers GM's full Gen-V LT platform lineup, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade from the mid-2010s through the early 2020s. If it runs an LT, this kit fits.

A few things worth noting for anyone doing this job regularly. Teardown is cleaner. A properly seated gasket pulls away without the prep work that comes with a sealant-only joint. That matters when you're turning jobs, not just doing one-offs.

Clamp load is consistent and repeatable. Same geometry, same seating behavior, every time. No install variables, no comebacks. Load distribution across the pan rail is even by design, which keeps gasket distortion out of the equation under torque. On a boosted or high-RPM build, that kind of oil system integrity isn't optional.

Manufactured in Concord, Ohio. American materials, same facility that's been producing precision sealing components for championship-winning engines for over 35 years.
