COMP Cams Evolution Hydraulic Roller Lifters are a revolutionary new patented tappet. They provide the most consistent and reliable performance of any lifters offered in the aftermarket. A combination of a self-contained hydraulic cartridge within a thick wall lifter body and accompanying reduced oil volume that is less effected by oil aeration delivers the most consistent bleed rates between each lifter on the market.
The smaller volume within the hydraulic cartridge creates one of the most responsive and quietest lifters on the market today. Startup noise is greatly reduced and a precision- controlled bleed down rate ensure s excellent performance at high RPM. The cartridge design also allows for an incredibly stiff lifter body, greatly reducing body distortion and further ensuring consistent hydraulic performance. This patented HCT tappet is not just a performance OE replacement – it is an all new, clean slate design started from a blank canvas that was developed specifically by COMP Cams to meet the demanding performance and durability required for modern street and performance street engines.
