Shopping around for a camshafts can be scary when it comes to the Mod motor. For years no one offered camshaftss or springs for the mod motor. The only thing available was a stock camshaft that was reground to questionable specifications. Additionally, the valve springs that were available were just as poorly designed. Nothing really worked and they always broke the valve springs. Things have changed a lot, but there are still some vendors out there that are offering poor quality products due to their own lack of knowledge. We have even found one vendor that is selling “performance cams” that is actually smaller than the factory camshaft.

The days of poor performance aftermarket cams are gone. RPM Outlet is proud to announce CROWER CAM Hi lift design camshafts. It is our choice for the best in mod motor camshafts. Crower Cams pioneered the Mod motor camshafts. We have been using Crower for years and have always had excellent results. Crower cam profiles offer faster valve openings and more area under the curve, which helps promote a broad torque and horsepower RPM band. Crower modular engine cams offer a unique valve train design which allowed Crower design engineers to push the limits on valve train acceleration rates, while still maintaining everyday driving reliability. All Crower Cams are ground on new steel billet cam cores.

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

CROWER CAM 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 Crower Cam Hi lift design camshafts.
