COMP Cams short travel XD hydraulic roller lifters offer the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. The XD versions feature heavy-duty tool steel pushrod seats. This adds strength and durability in extreme-duty applications, such as turbo drag cars and offshore powerboats. Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valvetrain. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. Now you have the best of both—with COMP Cams short travel XD hydraulic roller lifters. Order the model designed for your vehicle and engine application.

COMP Cams introduces another industry first with their Max-Lift BSR shaft rocker systems, a bolt-in bushed shaft rocker system that increases valve train stiffness helping your engine achieve higher levels of performance. By tying all eight rocker arms together on a single shaft that fits in the stock rocker stand, COMP Cams has found a way to improve valve train dynamics, increase valve train stiffness and reduce deflection under extreme loads. The increased valve train stiffness created the BSR rocker system allows your existing cam to act like a larger camshaft by transferring more of the motion to the valve or the use of more aggressive, higher lift cams without losing control of the valve train. Take complete control of your valves with the COMP Cams Max-Lift BSR shaft rocker system.

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.
