Endure-X Solid Roller Lifter Set for GM LS GEN III LS1/LS2/LS6/LS7/LSX

Sportsman Lifters from COMP Cams are designed to be a premium and lighter weight upgrade over Endure-X Lifters and a value alternative to the Elite Race option. Sportsman Lifters are offered in two configurations: a standard/traditional needle bearing axle/wheel design or an optional bronze bushing axle/wheel setup. And for Chevrolets, there are also left or right offset pushrod seat options. Each design features two pressurized EDM oil feeds to the axle, along with an edge orifice feed to the wheel. This design delivers a more reliable oil feed than most other options on the market. Sportsman Lifters also feature a shallower oil band than competitors’ versions for increased strength and rigidity, while internal machining helps to reduce weight. The body design utilizes a skirted wheel that strengthens the lifter ears and also provides more contact area with the lifter bore for further lifter stability. In addition, staked axles eliminate clips and provide robust axle retention. This permanent axle retention feature increases the stiffness of the lifter ears and helps prevent the ears from spreading. Sportsman Lifters are built from 8620 premium steel for increased strength and wear resistance and feature a captured link bar design. They utilize a tapered and slotted link bar tower for reduced weight and improved aesthetics. The lifters also feature a tall body to enable use in both standard and .300″ tall lifter bores – the result is increased strength and less lifter bore wear.
