Specs At A Glance

Good To Know

Q: Does this gasket fit both 4.8L and 5.3L engines? A: Yes, it is listed for both 4.8L and 5.3L LS applications, though confirming your engine code before ordering is recommended.

Q: Should head bolts be replaced during installation? A: Many LS engines use torque-to-yield bolts that are single-use, so new bolts are often required along with this gasket.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
