JE Pro Seal Head Gasket Suit LS1, LS2, LS3, LSX
Composite
Pliable, perforated metal-core composite gasket body eliminates coolant and oil leaks. No sealant needed!
Stainless Steel
Solid stainless cut-ring ‘bites’ into the cylinder head forming a positive barrier against combustion pressure leaks. No machining required!
Designed for use with high static compression or forced-induction engines which are prone to combustion pressure leaks when using typical composite or MLS head gaskets. Especially 4-bolt-per-cylinder patterns such as BMW, Subaru, Toyota and Chevrolet LS series.
