Evolution HCT Lifters offer quite operation expected from a hydraulic tappet and higher RPM demand by many of today's modern engine builds. Most consistent, highest performing, and quietest hydraulic lifter on the market.

COMP Cams Evolution HCT (Hydraulic Cartridge Technology) is a new patented tappet. The Evolution HCT tappet provides most consistent performance of any set of lifters in the aftermarket. A combination of self-contained hydraulic cartridge and accompanying reduced oil volume that is less effected by oil aeration delivers the most consistent bleed rates between each lifter. The smaller volume within the hydraulic cartridge creates one of the most responsive and quietest lifters on the market. Startup noise is greatly reduced and a precision controlled bleed down rate ensure excellent performance at high RPM. The patented 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 Original Equipment replacement. This is an all new bespoke design started from a blank canvas developed to meet the demanding performance and durability our customers desire.Also, as an industry first the hydraulic element of this patented lifter is serviceable, allowing anyone to rebuild their lifters in their own garage.
