In recent dyno tests on a Hemi engine using COMP’s #26918 beehive valve springs and upgraded exhaust, the XFI 265 netted 20 additional ft pounds of torque in lower rpm ranges with a peak of 31 additional hp. The XE 269 camshaft added 14 ft lbs of torque at low rpm and 47 additional peak horsepower. The amazing COMP Cams® XFI 269 camshaft yielded it’s most significant horsepower increases over 4500 rpm generating 61 more horsepower than the stock LS1 engine

When it comes to valve springs and titanium retainers, there is no better choice. COMP CAMS design engineers took the engines rpm capability, lightweight valve train, durability and other unique features, and designed the ultimate HEMI valve springs.

COMP CAMS BEEHIVE™ VALVE SPRINGS springs are made from a high tensile, super clean, chrome silicone material, the retainers are titanium, . In fact, the single beehive shaped spring uses the same manufacturing process for either their low-pressure street spring or their limited street and race spring. The springs are designed to work with cams up to 0.660" lift, and fit stock pockets without any machine work. These springs and retainers are a perfect compliment for the EXTREME Energy Camshafts.

COMP Cams® engineers have found that the pushrod is one of the most important members of the valve train and certainly the most taken for granted. Prior to extensive research at COMP Cams®, it was thought that the pushrod only had to be strong enough not to fail, bend or burn up at the ends. Now our engineers have learned that the frequency of the pushrod must match that of all the rest of the parts in the valve train, as well as the rpm at which the engine will be run. Today’s engines demand the highest quality components at every step and COMP Cams® Hi-Tech™ Pushrods fill that requirement.

The one-piece design from .080” wall seamless chromemoly tubing ensures the ultimate in strength and durability. The ends are precision formed, yielding added thickness in the critical tip area for strength, while maintaining constant wall thickness and concentricity. High-Tech pushrods are heat-treated ensuring compatibility for maximum strength.

COMP Cams® engineers have developed a fix for the well known poor designed OEM rocker arm and valve-train on the GM GEN III engines. Extensive research at COMP Cams®, R&D facility have yielded the GM GEN III Pro-Magnum Rocker Arm Upgrade Kit.

Featuring COMP Cams® Pro Magnum Roller Rockers, guide plates, rocker arm studs & poly-locks. Everyone knows that the COMP Cams® Pro Magnum Roller Rockers™ are the ultimate street rocker. Deigned with the serious performance enthusiast in mind. COMP Cams® Pro Magnum™ rockers will develop between 15 and 30 horsepower over your OEM rockers! Why? The secret is that not only does the roller tip reduce friction, the super stiff design and super accurate ratios yield more effective valve lift. The roller tip design also reduces friction by not scrubbing the valve end or pushing the valve stem hard against the valve guide.

COMP Cams Guide plates are a necessity in high performance engines. They keep your pushrods in line with your lifter cups and rocker arms, preventing deflecting or walking sideways, and are hardened to prevent from wearing prematurely.

COMP Cams rocker arm adjusting nuts (poly-locks) are designed for the ultimate in strength and locking force. Precision-ground for minimum runout, and tapered for extra strength in the locking area. Special alloys in the poly-locks ensure a quality and strength not found in any other competitive products.
