Sealed Power Hydraulic Lifters

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.
