S&S CYCLE Camshaft Kit – Easy Start – MR103 Gear Drive – Twin Cam ’99-’06 (except ’06 Dyna)

Features

• Allows for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance
• Designed as bolt-in cams for 103″ engine with stock 9.7:1 compression ratio up to 10.5:1
• More power across the rpm range best results from 2500 rpm – 5500 rpm
• Includes camshafts, gear cover gasket, bearings, retaining ring, o-ring, threat lock and instructions
• Made in the USA

Notes

• Includes 4-gear set.
• Due to the inherent characterics of gear drives, there may be more valve train noise.
• Works with stock, un-ported heads, but is great for S&S CNC ported heads.
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
• Not for models with OEM compression releases.

DISCLAIMER:Not legal for sale or use in California on any pollution controlled motor vehicles.
