Add More Lift and Duration with COMP Cams Evolution Hydraulic Roller Lifters

You can add more lift and duration at the cam with a set of COMP Cams Evolution Hydraulic Roller Lifters. The lifters are built using COMP’s patented Hydraulic Cartridge Technology. Essentially, the lifters have a removable hydraulic cartridge with a smaller volume of oil than conventional hydraulic roller lifters. This reduces oil aeration to deliver consistent bleed rates between each lifter. That improves lifter responsiveness, especially at high RPM.

Other COMP Cams Evolution Lifter features include:
• Greatly reduced noise at startup
• Lifter body that is 18% thicker than conventional lifters to reduce distortion
• Two oiling channels ensure pushrods and rocker arms never starve for oil
• Stronger link bars stabilize the lifters throughout the RPM range
• Fully user-serviceable hydraulic cartridges

This COMP Cams video shows you how the Evolution Hydraulic Roller Lifters and HCT design work.

COMP Cams Evolution Hydraulic Roller Lifters are available for all popular Chevy, Ford, Mopar, Oldsmobile, and Pontiac engines.
