Cylinder Head and Valvetrain Components

These COMP Cams Pro Magnum hydraulic roller lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic roller camshaft, high rpm is limited by the improper positioning of the internal piston, as the lifter inevitably "pumps up." This improper location results in broken valves and, therefore, leads to lost power or sometimes even engine failure. These lifters offer a distinct advantage over standard high performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used.

These High Energy hydraulic roller lifters are for use with the newly designed hydraulic roller cam series from COMP Cams, or as performance replacements for stock hydraulic roller lifters. You must be certain that the lifters are correct for the type of block used.

Patented Endure-X roller lifters from COMP Cams set the standards for solid roller lifter technology. These Endure-X roller lifters are fully heat-treated, machined to ultra-high tolerances, and fully rebuildable.

The Tilden Motorsports Variable Valve Timing (VVT) Delete Kit is designed to be used when converting a VVT cam to a non-VVT 3 bolt cam. This kit includes new timing cover with sensor, timing cover gasket, timing cover bolts, and  ARP cam bolts.
