Famous for its reliability, the Sealed Power line of internal engine components is engineered to work together as a system, eliminating the hassle of mixing and matching parts. Using proprietary forging, casting, and machining techniques, Sealed Power manufactures pistons and piston rings for everything from stock rebuilds to high-compression race engines. The company also manufactures crucial parts like oil pumps and pickups, camshafts, lifters, rockers, timing chain sets, valves, and valve springs, all with that same level of quality and durability. And to keep that power where it belongs, rely on Sealed Power gaskets, gasket sets, and freeze plugs.
