{"product_id":"mls-head-gasket-3-840-bore-040-thickness-rhs","title":"MLS Head Gasket, 3.840\" Bore, .040\" Thickness, RHS","description":"The Cometic C5721-040 is a Multi-Layer Steel (MLS) head gasket engineered for Buick 3800 Series II\/III V6 engines with a 3.840-inch bore. This specific gasket is for the right-hand side (RHS) cylinder head and has a compressed thickness of .040 inches. MLS gaskets are known for their superior sealing capabilities under extreme conditions, offering greater tolerance to temperature and pressure fluctuations, making them ideal for modified engines.\n\nCometic recommends installing MLS gaskets dry, as they are coated with a .001-inch thick Viton rubber sealant that should not be supplemented with additional sealants.\n\nThe Cometic C5721-040 head gasket is compatible with a range of vehicles including Buick models like the LeSabre, Park Avenue, Regal, and Riviera (1996-2003). It also fits Chevrolet Camaro (1996-2002), Impala (2000-2003), Lumina (1998-1999), and Monte Carlo (1998-2003). For Oldsmobile, it fits the 88 (1996-1999), 98 (1996), Intrigue (1998-1999), LSS (1996-1999), and Regency (1997-1998). Pontiac models include Bonneville (1996-2003) and Firebird (1996-2002), as well as Grand Prix (1997-2003).
