- 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
- Installer must check coil bind, valve to valve clearance and valve to piston clearance.
