• Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes, making higher cam lifts possible
• Increase valve timing accuracy by eliminating timing chain lash and loosely fit stock chain
• Provides strong low end torque and horsepower
• Strongest from 1500-5000 rpm
• Material must be removed from inner surface of the stock gear cover to install
• A hydraulic press and other professional level tools are required for installation
• Cam bearings and gaskets must be replaced
• S&S recommends that adjustable pushrod/cover kit be used (sold separately)

• Installer must check coil bind, valve to valve clearance and valve to piston clearance.
• Not recommended for engines having compression ratios greater the 10.1:1.
