CAMS MR103C-EZ 07-14

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 Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions Made in the USA Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. Not for models with OEM compression releases. Works with stock, un-ported heads, but is great for S&S CNC ported heads. More power across the rpm range best results from 2500 rpm - 5500 rpm
