• Designed for 88/96/103/110 cubic-inch engines with compression ratios from 10.0:1 to 10.5:1
• Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes making higher cam lifts possible
• Increases valve timing accuracy by eliminating chain lash and loosely fit stock chain drive
• Material must be removed from inner surface of the stock gear cover to install
• 3500-6000 rpm for 88" to 103" engines and 2500-5500 rpm for larger engines
• A hydraulic press and other professional level tool are required for installation
• S&S recommends that adjustable pushrod/cover get be used
• Cam bearings and gaskets must be replaced when installing new cams
• Kit includes camshafts, inner gears, outer gears, inner bearings, outer bearings, gasket and instructions

Notes

• Installer must check coil bind, valve to valve clearance and valve to piston clearance.
• Due to the inherent characteristics of gear drives, more valve train noise may occur.

• Made in the USA
