• Head bolt replacement recommended.
• Torque-to-yield bolts are designed so that they can be elongated beyond their elastic limit into the plastic region without problems.
• When a specific tightening torque has been reached, the bolts are turned further through a defined angle, which pre-loads them into the plastic region. Consequently, no retorquing is necessary.

COMP Cams Hydraulic Roller Lifters are a performance upgrade for stock hydraulic roller lifters or retro-fit hydraulic roller lifters for non-roller blocks. The roller wheel decreases friction and increases longevity when compared to flat tappet lifters. Hydraulic roller lifters can handle much more aggressive cam profiles than flat tappets unlocking performance potential.

Product Features:

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.

These short travel retro-fit hydraulic roller lifters feature a short travel. These lifters’ short travel allows for light pre-load and reduced oil for the highest revving lifter for factory, RHS, LSX and Warhawk LS.
