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.

Powertrax Grip Pro traction systems are the latest design in differential technology. They combine the smooth operation of a limited-slip differential, with the strength of a fully machined, forged steel case. Using 3x2 spiral gear engineering, the Powertrax Grip Pro delivers progressive and variable traction. Based on throttle input, you are in control of how much traction is applied. These differential systems are great for use where finesse is just as important as brutal traction. On the road or track, in the rain or snow, Grip Pro is a winner! The systems come fully assembled and there are no friction plates—so you can use any gear oil you like, including full synthetic and racing lube.

Snow Performance Boost Cooler Stage-2.5 water/methanol injection systems suppress detonation so that more power-producing timing can be utilized. Water, with its high latent heat of vaporization, cools the intake charge and combustion. Methanol cools the charge and combustion, but also acts like an extremely high-octane fuel (some researchers claim as high as 120 octane) and adds more oxygen to combustion. Complete with custom water-methanol injection throttle body spacer plate, braided stainless line, and 4AN fittings offering un-surpassed reliability and ease of install. They're designed for use in naturally aspirated carbureted gasoline vehicles.

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.
