These Sealed Power MA Series main bearings can actually polish the journals on your crankshaft. That's because there's a small percentage of silicon mixed in with the aluminum and tin that make up the bearing-surface alloy. The silicon is there for wear resistance, but its toughness actually smoothes the journals of a crank whose surface hasn't been optimized! This special surface alloy is laid over a high-strength 1010 steel backing and delivers improved seizure and corrosion resistance, as well as better control of wall variance. It also helps to minimize debris embedding, which can score the crank's surface.

Sealed Power valve stem seals control the lubrication of the valve stem as it slides into the valve guide. Too little oil contributes to stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and early valve failure, as well as reduced engine performance and emission failures. Sealed Power valve stem seals ensure dependable performance and superior service life.

Sealed Power hydraulic lifters are precision-manufactured to maintain precise valve timing under all operating conditions. A patented constant orifice metering valve provides precise oil metering to the overhead valvetrain, and longer plungers or pistons provide increased bearing surfaces, resulting in longer lifter life. Their check valves are lightweight flat discs, allowing for higher speeds and more uniform operation than competitive lifters.
