COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.

COMP Cams Race XD mechanical roller lifters are strong, durable, and versatile. They feature a lightweight modular design with interchangeable pushrod seats. Available in medium or large offsets with left or right placement, Race XD lifters are configurable to clear the most extreme intake angles. Two finishes are offered: REM finished bodies create an extra-smooth surface for reduced lifter body and bore wear; and the DLC-coated bodies further minimize friction for the ultimate in durability. For excellent strength in extreme operating conditions, COMP Cams also enhances their Race XD lifters with a proprietary bronze alloy roller wheel bushing and an oversized captured link bar to connect the individual lifters. In an effort to eliminate the culprit of most roller lifter failures, these bushed solid roller lifter sets have oiling systems that ensure consistent roller wheel and axle lubrication. Order the lifters recommended for your year/make and engine application.

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.
