Simply put, Zcams' function like a much 'bigger' cam (greater duration) yet they increase low-end and mid-range torque in the most often used rpm range. All Zcam profile increases the rate of acceleration during the cycle in which the valve is opening and as it approaches maximum valve lift. At max lift the Zcam then returns the valve to its seat, but only after maximum flow and cylinder filling has been achieved.

Peak horsepower and torque output are enhanced throughout the entire rpm range! New Crane Zcams' were also designed to minimize horsepower-robbing harmonic frequency pulses when matched with the recommended valve springs.

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

CRANE CAMS valve springs are made from a high tensile, super clean, chrome silicone material, the retainers are steel. 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 0.625" lift, and fit stock pockets without any machine work. These springs and retainers are a perfect compliment for the CRANE CAMS Camshafts.
