COMP Cams 81216 High Energy Chevy Hydraulic Lifters
                        

High Energy Hydraulic lifters have a patented constant orifice metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and pushrod seat is maintained, eliminating excessive oiling at high engine speeds. The pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength and wear resistance.

In addition, High Energy Lifters have a lightweight check valve disc that allows for quicker response, which results in increased engine speed before valve float. This check valve disc also maintains added control at all engine speeds and loads.

COMP Cams High Energy Hydraulic Lifters also contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity.

COMP Cams 159-12 Engine Break-In Lube Oil Additive
                        

ZDDP-enhanced Engine Break-In Lube Oil Additive from COMP Cams provides maximum engine life while also allowing it to reach its full performance potential. It does so by improving the surface mating of valve train components (especially flat tappets), rotating assembly, rod journals, piston rings, valve guides and other vital areas of the engine. This proprietary break-in lube formula includes the optimum amount of critical additives ZDDP (Zinc & Phosphorus), Molybdenum, detergents and high grade base oil.

The multi-viscosity, mineral-based COMP Cams Engine Break-In Oil Additive is fully-formulated and requires no additives or supplements. In addition, the oil is fully compatible with gasoline, methanol and high octane racing fuels.
