Description

The S&S Cycle MR103 Easy Start Camshaft Kit is engineered to provide an easy start by initially reducing crank compression. Once the engine starts and RPM increases, the compression release lobe retracts centrifugally, allowing the engine to run normally with full compression and no loss in performance. Designed as bolt-in cams for 103" engines with stock 9.7:1 compression ratios, this kit is optimized for engines with compression ratios ranging from 9.7:1 up to 10.5:1. Expect increased power across the RPM range, with best results from 2500 RPM to 5500 RPM. Compatible with stock, un-ported heads and optimized for S&S CNC ported heads, this kit provides versatility and performance gains for a variety of setups. Maximize your engine's potential with the S&S Cycle MR103 – designed and manufactured in the USA.
