Special Purpose Washers – Black Oxide

Harmonic Damper Bolts

Exhaust Header Bolt Kits are specifically designed and engineered for attaching exhaust headers to a street or strip vehicle, without the worry of leaky gaskets or loosening during operation.
Intake Manifold Bolts deliver unmatched performance, safety and optimum sealing of gasket surfaces for any street or strip vehicle. Rated at 180,000 psi tensile strength and precision machined.
High-Performance Head Bolt Kits are available with a reduced wrenching hex or 12-point, and wide flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing.
Special Purpose Washers are constructed from premium chrome moly with a black oxide finish. Available in a variety of sizes and thicknesses, and with or without I.D. (inside diameter) chamfers.
Harmonic Damper Bolts safely keep the damper locked into place as the crankshaft flexes and twists and the harmonic damper absorbs incredible amounts of kinetic energy.
