COMP Cams Chevrolet Small Block XD Short Travel Retro-Fit Hydraulic Roller Lifter Set

These short travel retro-fit XD hydraulic roller lifters feature a billet seat and short travel, allowing for light pre-load and reduced oil volume for a high-revving lifter. The Evolution Hydraulic Roller Lifters with Hydraulic Cartridge Technology is a patented tappet system designed for consistent bleed rates, responsive and quiet operation, and excellent performance at high RPM. The cartridge design ensures a stiff lifter body, reducing distortion and maintaining consistent hydraulic performance. Designed for modern street and performance street engines, they offer increased duration and lift to the camshaft, two oiling features, and a serviceable hydraulic element for rebuildability.
