COMP Cams Engine Camshaft Kit

COMP Cams Engine Camshaft Kits: The Complete Valvetrain Solution

When serious engine builders reach for a camshaft kit, few names carry more weight than COMP Cams. Founded in 1976, Competition Cams Inc. has been an industry leader in the production of top-quality valvetrain components, and their engine camshaft kits represent the pinnacle of that decades-long expertise. Rather than simply dropping in a new camshaft, a proper cam kit ensures that every component in your valvetrain works in concert — and that's exactly the philosophy behind every COMP Cams kit.

Why a Cam Kit — Not Just a Camshaft

Choosing a camshaft and valvetrain products isn't like buying an oil filter. Everything in your valvetrain is part of a complex interlocking system that needs to perform well as a combination. COMP Cams answers this challenge with tiered kit configurations. Camshaft & Lifter Kits include the camshaft, lifters, assembly lube, decals, and instructions; Complete Kits add timing chain & gears, valve springs, retainers, and locks; and Small Kits include the camshaft, lifters, timing chain set, assembly lube, decals, and instructions. This means builders can choose the level of upgrade that suits their project without worrying about sourcing mismatched parts.

Signature Technologies Inside Every Kit

What separates a COMP Cams kit from a generic alternative is the proprietary engineering baked into every component. COMP Cams developed a surface finishing process called Micro Surface Enhancement (MSE), which removes peaks from the surface finish at a nanoscale level, improving bearing surface performance and the life span of camshaft lobes and bearing journals. Additionally, COMP Cams developed the process of ion nitriding for camshafts, known as Pro Plasma Nitriding — a 36-hour process that uses pulsed nitrogen plasma in a vacuum-controlled environment to embed nitrogen ions into the camshaft surface, significantly hardening it.

For forced-induction applications, the HRT series stands out. The HRT Camshaft Series uses the newest and most advanced lobe designs from COMP Cams to produce some of the highest average power and torque increases available for turbo and supercharged engines, featuring "Low Shock Technology" lobe profiles designed to maximize horsepower while improving stability at higher RPM — and these profiles are easier on valve springs, enhancing durability and reducing load loss.

A Cam Series for Every Application

Browse the full range of engine camshaft kits and you'll find COMP Cams has engineered a solution for virtually every platform and power goal. Within the COMP Cams camshaft family, there are several types of camshafts available for most popular domestic engines, ranging from the Xtreme Energy Cams™ to Nitrous HP™ Cams. The popular Thumpr series delivers that classic muscle-car lope, while the Xtreme Energy series targets street/strip enthusiasts who demand both throttle response and top-end horsepower. Forced-induction builds can choose kits specifically designed for maximum power on supercharged and turbocharged street and street/strip applications, available in mild to aggressive specifications.

COMP Cams manufactures hydraulic and solid flat tappet cams, hydraulic and mechanical roller cams, and overhead cams for everything from OE replacement to full race, naturally aspirated, supercharged, turbocharged, or nitrous-injected engines. For the ultimate in race-winning reliability, every part in their competition-grade kits incorporates the same technology used in NASCAR and NHRA competition.

Engineering Backed by Decades of Racing

COMP Cams created the "Spintron" engine testing system, which uses an electric motor to drive a dummy engine outfitted with high-speed sensors and cameras to record data about valvetrain dynamics, observing valve-spring seat pressure, coil dynamics, camshaft and pushrod flex, and lifter movement. This level of R&D investment translates directly into cam kits that are proven before they ever reach your engine — making COMP Cams a trusted choice for everything from weekend street machines to championship-winning race builds.
