• Reverses the rear cam's direction of rotation to provide additional operating clearance between cam lobes, allowing higher cam lifts.
• Increases valve and timing accuracy by eliminating timing chain lash and loosely fit chain drives.
• Works with stock, unported heads; S&S CNC ported heads are recommended for best performance.
• Material must be removed from the inner surface of the stock gear cover for installation; a hydraulic press and professional tools are required.
• S&S requires the use of the adjustable pushrod/cover kit when installing this camshaft kit.
• Cam bearings and gaskets must be replaced when installing new cams.
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance during installation.
• Best power band from 3000–6000 rpm; due to the inherent characteristics of the drive system you may experience increased valve train noise.
• Not a bolt-in camshaft kit; professional installation is strongly recommended.
• The kit includes camshafts, inner gear, outer gear drives, inner bearings, outer bearings, gaskets and instructions. 🇺🇸
