COMP Cams Hydraulic Roller Lifters are a performance upgrade for stock Hydraulic Roller lifters or retro-fit Hydraulic Roller lifters for non-roller blocks. The roller wheel decreases friction and increases longevity when compared to flat tappet lifters. Hydraulic Roller lifters can handle much more aggressive cam profiles than flat tappets unlocking performance potential.
- Patented orifice metering valve 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
- Pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength and wear resistance
- Contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity
- Lightweight check valve disc allows for quicker response, which results in increased engine speed before valve float
- Lightweight check valve disc maintains added control at all engine speeds and loads
