Emissions Warning: This product is not designed for public highway or street use, and is only legal for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street.

Includes 1 or 2 camshafts, depending on how many your engine uses.

New: Skunk2 camshafts now use AMAX and Fast Ramp Technologies (the same used in F1 racing) to maximize the area under the lift curve and reduce seat timing, which maximizes torque and cylinder pressure. These technologies allow greater gains without compromising reliability and valvetrain stability! Skunk2 also is using newly revised camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects.

Skunk2 Ultra Series camshaft profiles are designed using the latest computerized valvetrain and modeling techniques to maximize horsepower and torque. The Skunk2 Ultra Series camshafts are designed utilizing years of racing experience. These camshaft blanks are cast from the same foundries used by auto manufacturers such as Toyota, Nissan, Honda, and Mitsubishi, and utilize the latest in Japanese chill-casting technology. Skunk2 Ultra Series camshafts are ground to exact specification using CNC cam grinding machines and are subjected to hours of performance and durability testing. Skunk2 Ultra Series camshafts must pass stringent quality control standards that exceed OEM requirements.

The Ultra Series cams differs from the Tuner and Pro Series by dramatically increases both horsepower and torque yet retaining complete valvetrain stability and exceptional engine response. The lower stage cams allow for stock style idle and provide large gains between the mid and high range of the RPM band. These Ultra Series cams also feature a cam profile unique to Skunk2 that allows for exceptional operation at any RPM level. The Ultra Series camshafts are perfect for those looking to get the most out of their builds.

Features:

• Top quality materials and proprietary forging methods that ensures extreme performance and operation.
• DIC (Drop In Camshaft): Some Stage 1 cams are a "drop-in" style, designed for stock engines with some bolt-on modifications. Upgraded valvetrain not needed unless using aftermarket forced induction upgrade.
• Stage 1: Usually designed to be a DIC (Drop-In Camshaft). Provides a stock style idle for smooth overall operation. Optimized for torque and most aggressive at mid-range RPM.
• Stage 2: Street/Race cam designed for engine with free-flowing intake and exhaust tracts and increased compression. Retains a stock style idle. Will require upgraded valvetrain.
• Stage 3: Street/Race cam designed for engines that require the top-end power to carry into higher RPMs than what is possible with Stage 2 cams. An aggressive design that does not retain a stock style idle. Upgraded valvetrain required.
• Stage 4: Race style cam designed for serious race cars. An aggressive profile that requires an upgraded valvetrain and careful tuning. Provides a aggressive crossover and best suited for turbo setups.

Tuning Notes: To ensure proper idle, air/fuel ratio, and peak performance, a tune is always recommended when upgrading to any Skunk2 camshaft. For some applications, adjustable cam gears and cam degreeing may be required.
