Chry Sb Hi-Tech Roller Lifters

The Chry Sb Hi-Tech Roller Lifters from COMP CAMS represent a significant upgrade for Chrysler small-block engine builders seeking maximum reliability and performance gains. These roller lifters are engineered for enthusiasts and professional mechanics who demand reduced friction, improved valve control, and extended engine life. Whether you're building a street machine, competition engine, or restoring a classic Mopar, roller lifters eliminate the flat-tappet cam wear patterns that plague conventional hydraulic lifters, making them an essential component for any serious small-block Chrysler project.

Hi-Tech roller lifters feature precision-engineered needle bearings that roll across the camshaft lobe, drastically reducing parasitic friction losses compared to sliding contact lifter designs. This rolling action allows for steeper cam ramps, higher RPM capability, and more aggressive valve events without sacrificing valve train stability. The needle-roller design distributes contact pressure over a larger surface area, which translates to lower wear rates, better oil distribution within the lifter body, and superior longevity even under high-RPM or boost conditions. COMP CAMS' manufacturing tolerances ensure consistent fitment and quiet operation, while the compact footprint accommodates standard Chrysler small-block bore patterns without modification.

These lifters are ideal for 318, 340, and 360 Chrysler small-block engines running aggressive roller camshafts that would otherwise overload or destroy conventional hydraulic lifters. Installation requires careful bore preparation and proper oil supply verification to the lifter galleries—a critical step that separates a successful build from premature failure. The set must be paired with a compatible roller cam, timing chain, and appropriate pushrods to ensure correct geometry and load transfer. Proper break-in procedure and frequent oil changes during the first 500 miles are essential to allow the needle bearings to seat correctly and maximize component longevity in your Chrysler small-block build.
