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

The S&S Camshaft Kit adds power and throttle response with a performance cam profile built for your engine.

This is the MR103 grind. See the cam specs for lift, duration and valve events, and confirm your engine's compression and valvetrain are matched to the cam before installing.

Fits Harley-Davidson Touring (1999-2006), Softail (2000-2006) and Dyna (1999-2005) models. Check the fitment chart below to confirm your exact year and model.

• 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, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions
• Made in the USA
• 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.
