Specification Details
SKU SS-755818
Material Multi-layer stainless steel
Engine family GM LS Gen III / IV small-block applications
Use Matched header-gasket replacement

Choose the right gaskets for your LS header refit

The Kooks SS-755818 uses multi-layer stainless steel for the listed GM LS Gen III and IV small-block header applications. It is a useful replacement specification when servicing a matched exhaust installation and choosing the gaskets to suit the actual engine family.

SKU: SS-755818

Match LS and LT applications separately

This is the LS Gen III/IV specification. Gen V LT headers use a different gasket listing. Match the head and header flange to the correct engine family before arranging the refit.

For service and replacement fitting

Kooks header packages generally include their gaskets. Choose replacements when the existing installation needs them, and follow the header fitting instructions for tightening and the first heat-cycle check.
