Description

The HP shim technology increases clampload around the combustion chamber, thereby increasing the sealability of the head gasket around the open deck block.

Product Overview

The HP shim technology increases clampload around the combustion chamber, thereby increasing the sealability of the head gasket around the open deck block.


Features and Benefits
