Sealed Power Hydraulic Lifters
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.

Cloyes Hex-A-Just Timing Sets
With Cloyes Hex-A-Just timing sets, infinitely adjustable cam timing is as simple as turning an Allen wrench. Consisting of SAE 1144 billet steel cam and crank sprockets and a true roller timing chain, these timing sets use a special hex-head bushing installed on your cam's dowel pin. This bushing lines up with degree marks on the cam sprocket. You can adjust timing in fractions of a degree (as much as +/-6 degrees) by loosening the cam bolts and turning the bushing with an Allen wrench. Cloyes Hex-A-Just timing sets install under your stock timing cover and can be used in align-bored blocks. Order the model designed for your vehicle and engine application.
