Full Engines, Internal Parts, Pistons/Rods

Now available! For the B15 or B16. .030" standard thickness, 89mm bore size. Custom sizes available but take several weeks to produce. Using 1mm oversize pistons, choose 90mm bore size. Provide maximum sealing performance for today’s high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. Learn More
