Product Description
GASKET HEAD 4.125" .032" MLX TWIN CAM 99-17
- Manufactured from premium fuel-resistant materials that will not creep, crack or become brittle
- 4.125" big bore is a popular big bore for performance-oriented Harleys, as it builds serious cylinder pressure and can use the extra sealing properties of the MLX head gaskets
- Center layer is folded over on top of itself which simulates an O-ringed head and adds a targeted torque load right at the combustion seal where you need it
- MLX head gaskets are essential for all Twin Cam applications using a Turbo, high compression, nitrous or any power adder modifications
- Proprietary high-temperature coatings along with embossments provide a micro seal for fluids against the head and block surface
- Require no special machining and are installed like a regular MLS head gasket
- Sold in pairs for popular bores and thicknesses
- Made in the USA
