Description

The Cometic Cadillac 4.6L 32V 94mm RHS .040in MLS Head Gasket offers maximum sealing performance for high-output engines and requires no sealants. Its Multi-Layer Steel (MLS) construction, featuring multiple embossed stainless steel layers, provides superior strength, rebound, and corrosion resistance. This design is ideal for mating aluminum heads to either aluminum or cast iron blocks, effectively withstanding the shearing forces between dissimilar materials. The outer layers of the gasket are coated on both sides with Viton, a heat-resistant elastomer capable of withstanding temperatures up to 250°C (482°F), ensuring durability in demanding environments. The uncoated stainless steel center layer can be varied to accommodate different thickness requirements, with this specific gasket having a compressed operating thickness of 0.040 inches. This is a Right Hand Side (RHS) gasket. This Cometic head gasket is specifically designed to fit the following vehicles: - 2006-2008 Buick Lucerne (CXL, CXS) - 2008-2011 Buick Lucerne (Super) - 1993 Cadillac Allante (Base, Indianapolis 500 Pace Car, Value Leader) - 1996-2005 Cadillac DeVille (Base, Concours, d'Elegance, DHS, DTS, Protection Series) - 2006-2011 Cadillac DTS (Base, Livery, Luxury, Platinum, Premium) - 1994-1997 Cadillac Eldorado (Base, Sport, Touring) - 1998-2002 Cadillac Eldorado (ESC, ETC) - 1994-2004 Cadillac Seville (SLS, STS) - 2004-2009 Cadillac SRX (Base) - 2005-2010 Cadillac STS (Base, Platinum) - 2004-2008 Cadillac XLR (Base, Platinum) - 2004-2005 Pontiac Bonneville (GXP)
