Easy Start MR103 camshaft kit

Allows easy starting by initially reducing compression; once the engine starts and rpm rise, the decompression cam retracts by centrifugal force and the engine runs normally, with full compression and no loss of performance
Designed as bolt-in camshafts for 103" engines with original compression ratio from 9.7:1 up to 10.5:1
More power across the entire rpm range, better results between 2,500 and 5,500 rpm
Includes camshafts, cover gasket, bearings, retaining ring, O-ring, threadlocker and instructions
Manufactured in the USA
Compatible with original cylinder heads without modification, but optimal for S&S CNC ported cylinder heads.
The installer must check the spring compression limit, valve clearance and valve-to-piston clearance.
Not suitable for models with OEM decompressors
Includes set of 4 gears.
Due to the inherent characteristics of gear drives, there may be increased noise in the valve train.
