ISR Performance Multi Layer Exhaust Manifold Gaskets (pair) - Chevrolet LS

Our multi-layer steel exhaust manifold gaskets for the Chevrolet LS engine family. Sold as a pair, one per cylinder bank. The right gasket to run with any aftermarket header or manifold install on an LS, including our LS swap header kits.

What It Does

Replaces the factory exhaust manifold gaskets at both heads with a multi-layer steel design that holds bolt clamping load far better at the temperatures an LS sees under load. The multi-layer construction is the standard for forced induction and high-output naturally aspirated builds because single-layer composite gaskets give up clamping force as they heat soak. These hold their seal.

Fitment

Fits all Chevrolet LS-series engines (LS1, LS2, LS3, LS6, LS7, LSX, LQ4, LQ9, and related truck variants). Works equally well in stock GM platforms and in LS swap applications. Common companion to our ISR LS swap header kits (IS-SSHD-350LS for 350Z/G35 LS swaps).
