COMP Cams High Energy Hydraulic Lifters

These High Energy hydraulic lifters from COMP Cams feature a patented, constant orifice-metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the pushrod seat is maintained throughout the engine's rpm range, eliminating excessive oiling at high speeds. The pushrod seat is made of a special powdered metal iron alloy, heat-treated for strength and wear resistance. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity. These lifters have a lightweight check valve disk that allows for quicker response, resulting in increased engine speed before valve float.

Rollmaster Gold Series Timing Sets

Rollmaster Gold Series timing sets feature Nitride camshaft and crankshaft sprockets. They're lightweight and stronger than any other timing sets available, due to the weight savings of billet steel and use of CNC machinery. All sets have billet steel crank and camshaft sprockets which have been 100 percent CNC-machined for reduced wear and improved accuracy. Rollmaster Gold Series timing sets come standard with a premium grade one-piece Iwis full roller chain, produced in Germany and built to the highest possible quality standards. The sets have nine keyways, allowing you more adjustments for dialing in the camshaft to your liking. Multiple keyways are a solid fixture and tend not to move or work loose like offset bushings or dowels--providing a positive locking of the cam timing to whatever position is desired.
