Specs At A Glance

Good To Know

Q: Does this kit fit both cathedral and rectangular port LS engines? A: This kit is listed for 5.3L and 6.0L LS-series engines plus LS1 and LS2, so confirm your specific engine code and valley pan design before ordering.

Q: Why replace the valley pan gasket and cover plate together? A: Oil reaching the knock sensor recess can cause false knock readings, so renewing the gasket and cover plate as a set restores the seal and protects sensor performance.

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