COMP Cams is bringing the muscle car sound back, and it's nastier than ever! Let's face it--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 you demand, COMP Cams engineering team proudly introduces the Thumpr Series cam and lifter kits. 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 to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in 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 deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large-diameter valve springs, retainers, and locks, without clearance or fitment issues. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. These unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem "side loading" that causes premature valve guide wear.

These High Energy hydraulic lifters from COMP Cams feature a patented, constant orifice-metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the pushrod seat is maintained throughout the engine's rpm range, eliminating excessive oiling at high speeds. The pushrod seat is made of a special powdered metal iron alloy, heat-treated for strength and wear resistance. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity. These lifters have a lightweight check valve disk that allows for quicker response, resulting in increased engine speed before valve float.

The new COMP Cams DLC High Energy hydraulic lifters perform mechanically just as COMP's well-known High Energy line, but with the added benefit of a DLC surface treatment. This produces a flat tappet lifters with an extremely hard, tough, and slick face that reduces friction at the cam lobe. The unique coating extends the life of the lifter and camshaft, significantly reducing the likelihood of a flattened cam lobe. Additionally, COMP Cams DLC High Energy hydraulic lifters virtually eliminate the need for the traditional break-in procedure associated with cast iron camshafts and flat tappet lifters. They maintain the excellent hydraulic performance that the High Energy Hydraulic Lifters have provided for many years.

COMP Cams Evolution Series hydraulic roller lifters with Hydraulic Cartridge Technology (HCT) are revolutionary patented tappets. A combination of a self-contained hydraulic cartridge within a thick-wall lifter body and accompanying reduced oil volume that is less effected by oil aeration delivers the most consistent bleed rates between each lifter on the market. The smaller volume within the hydraulic cartridge creates one of the most responsive and quietest lifters on the market today. Startup noise is greatly reduced, and a precision-controlled bleed down rate ensures excellent performance at high RPM. The cartridge design also allows for an incredibly stiff lifter body, greatly reducing body distortion and further ensuring consistent hydraulic performance. The patented HCT tappets are a completely new design that was developed specifically by COMP Cams to meet the demanding performance and durability required for modern street and performance street engines. The HCT and proprietary manufacturing processes of these lifters ensure precision and longevity that exceed any lifter on the market. Other features include increased duration and lift to the camshaft and two oiling features. Another industry first is the fact that the hydraulic element of this patented lifter is serviceable, allowing anyone to rebuild lifters in his or her own garage. Order the Evolution lifters recommended for your year/make and engine application.

Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. COMP Cams valve springs are offered in single and dual styles to meet your cam requirements.
