COMP Cams Sportsman Solid Roller Lifters
COMP Cams Sportsman solid roller lifters feature premium-quality, high-value components designed for sportsman and professional racing, along with high-end street machines. They're available in both needle-bearing and bushing configurations. Each design features two pressurized EDM oil feeds, as well as an edge-orifice feed to the wheel. This delivers a more reliable oil feed than most competing options. COMP Cams Sportsman solid roller lifters are also designed with a shallower oil band than competitors' versions for increased strength and rigidity, while internal machining helps to reduce weight. The body utilizes a skirted wheel that strengthens the lifter ears, and the skirt also provides more contact area with the lifter bore for further lifter stabilization. In addition, staked axles eliminate clips and provide robust axle retention. This feature increases the stiffness of the lifter ears and helps to prevent the ears from spreading. The COMP Cams Sportsman solid roller lifters are built from 8620 premium steel for increased strength and wear resistance and they feature a captured, stainless steel link bar design. The lifters also utilize a tapered and slotted link bar tower for reduced weight and improved aesthetics. Choose the size and options tailored for your engine application.
