COMP Cams Evolution Hydraulic Roller Lifter Set 265-400 Chevrolet Small Block - Set of 16

The COMP Cams Evolution HCT (Hydraulic Cartridge Technology) lifters feature a patented, self-contained hydraulic cartridge design. This unique approach uses a smaller oil volume within the cartridge, making it less susceptible to oil aeration and ensuring more consistent bleed rates across all lifters in the set. This results in a highly responsive and remarkably quiet lifter, significantly reducing startup noise and providing excellent performance even at high RPMs thanks to a precisely controlled bleed-down rate.

Beyond their consistent hydraulic performance, these lifters boast an incredibly stiff body, minimizing distortion and further contributing to their reliable operation. This isn't just an upgrade over stock; it's a completely new design built from the ground up to meet the high-performance and durability demands of modern engine builds. A notable feature is that the hydraulic element of these patented lifters is serviceable, meaning you can rebuild them yourself in your garage.

This set includes 16 lifters, enough for a complete Chevrolet Small Block engine. They are designed for demanding performance applications where consistent operation and durability are paramount.
