In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the 2003-2008 Dodge HEMI RAM Truck and Durango.

We have invested many hours evaluating and refining each of the Dodge HEMI RAM Truck / Durango products on a MD Chassis DYNO, to ensure that we could develop as much power as possible, as safely as possible.

The site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.

COMP CAMS XFI™ Camshafts Hemi-powered Late-Model Chrysler/Dodge Vehicles
Three different camshaft combinations for the Hemi 5.7L Net power increases up to 61 HP

New Comp Cams Hemi Camshafts COMP Cams® New XFI™ (Xtreme Fuel Injection) camshafts for Hemi-powered Chrysler vehicles dramatically increase engine horsepower and torque, yet retain compatibility with reprogrammed OEM vehicle computer systems. Available in three different profiles (XFI 260, 268 and 273); the new camshafts are application-specific with designs for street performance and towing.

In recent dyno tests on a Hemi engine using COMP’s #26918 beehive valve springs and upgraded exhaust, the XFI 260 netted 20 additional ft pounds of torque in lower rpm ranges with a peak of 31 additional hp. The XE 268 camshaft added 14 ft lbs of torque at low rpm and 47 additional peak horsepower. The amazing COMP Cams® XFI 273 camshaft yielded it’s most significant horsepower increases over 4500 rpm generating 61 more horsepower than the stock Hemi 5.7-liter engine

COMP CAM Hi-Tech™ Pushrods
for the HEMI 5.7L and 6.1L V8

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.

for the HEMI 5.7L and 6.1L V8

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.
