Description

This two-piece black aluminum timing cover is built to replace a cracked, warped, or leaking factory timing cover on GM LS1/LS6 engines — 5.7L/346 in³, 1997-2004. The two-piece design seals the timing chain area while giving the front of the engine a clean, finished appearance.

This is a cover-only part: gasket, crankshaft seal, and mounting hardware are not included, and it does not include a camshaft position sensor provision, sensor harness, or timing pointer. Plan to source these separately based on your engine's needs. Confirm timing cover style, balancer clearance, and sensor provisions before installation.
