Multi-Layer Head Gasket 4.080" Bore, .051" Thick CL54660

Multi-Layer Head Gasket 4.080" Bore, .051" Thick 54660 CL54660 Suit GM LS 6.0L, 6.2L 2007-14 LS3 MLS CYLINDER HEAD GASKET MAHLE performance MLS head gaskets are comprised of 3 stainless steel layers. Sealing beads surround the combustion chamber and coolant passages emphasizing clamp load in these specific areas.

Precision tooling provides optimum bead height, width, profile, and bore concentricity.

Comprised of multiple embossed layers of FKM (fluoroelastomer coated) and uncoated 301 stainless steel

Handle any application from naturally aspirated to boost or nitrous

Embossed outer layers of the gasket meet the demands of a variety of harsh sealing environments, load conditions and sealing surface finishes

Design requires less clamp load creating less bore distortion and conforms load distribution across the sealing surface

Center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements

No sealants or re-torque required
