Product Details

Features

  • Neoprene/steel core gasket seals the valley cover, prevents oil leaks
  • Direct replacement for LS2/LS3/LS7/LSX valley cover reinstallation
  • Fits GM LS2/LS3/LS7/LSX engines and LSX performance blocks

Description

This valley cover gasket is built for GM LS2/LS3/LS7/LSX applications, supporting 6.0L, 6.2L, and 7.0L engine combinations, as well as LSX performance engine blocks, where the matching valley cover pattern is required.

Neoprene rubber/steel core construction seals the valley cover to the engine block, helping control oil leaks, crankcase sealing issues, and intake valley contamination during engine refreshes or LS swap work. Use this gasket when replacing, refinishing, or servicing a compatible LS valley cover — including TSP's LS2/LS3/LS7/LSX finned or trussed valley covers. Confirm knock sensor location, AFM/DOD provisions, and cover style before installation.


Applications
Fits GM LS Series V8 engines: 6.0L/364 (LS2, L76, LY6, L96), 6.2L/376 (LS3, L92, L99), and 7.0L/427 (LS7), plus LSX performance engine blocks. Common applications include Chevrolet Corvette/Camaro, Pontiac GTO/G8, Chevrolet Silverado/GMC Sierra (LS swap or LS-equipped), and LS swap/performance engine builds.

Installation
One-piece gasket, 10 bolt holes. Verify valley cover gasket pattern, gasket shape, knock sensor location, and AFM/DOD configuration before installation. Crank seals not included.
