COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In an ongoing quest to provide you with the performance and sound that you demand, COMP Cams' engineering team proudly introduces the Thumpr Series hydraulic roller cam and lifter kits. They are designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap. They're designed to maximize the rough-idling characteristics of the cams, giving you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. They are available in three different grind profiles. Each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits feature a cutting-edge hydraulic roller design that delivers a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

Many of the late model blocks have taller lifter bores, which means standard seat height lifters with an offset require manual notching of the lifter bore for pushrod clearance. Crower developed a lifter with a +.300 in. higher pushrod seat to solve this problem. Crower Dart block raised seat roller lifters are taller to clear lifter bore and have lightweight billet alloy bodies paired with a robust stainless steel alignment blade. They feature High-Pressure Pin Oiling (HIPPO), allowing more oil to be delivered to critical high-load areas for greatly improved cycle life.

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.
