Clay Smith Cams Hydraulic Hi-Rev flat tappet lifters are made in the USA and of the Highest Quality available.
These 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 valve train, 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.
