Description

COMP Cams® Evolution Hydraulic Roller Lifters are the first lifters EVER created using the newly patented Hydraulic Cartridge Technology (HCT)! This revolutionary design offers the most reliable performance of any lifters 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 affected 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 today. Startup noise is greatly reduced and a precision-controlled bleed down rate ensures excellent performance at high RPM. The cartridge design allows for an incredibly stiff lifter body that greatly reduces body distortion and further ensures consistent hydraulic performance.

HCT and proprietary methods ensure unparalleled precision and longevity
Developed specifically to meet performance and durability demands of modern street/performance street engines
Hydraulic element is serviceable, allowing anyone to rebuild
Precision-controlled bleed down rate ensures excellent performance at higher RPM's
