- Performance intake and exhaust is recommended for maximum performance increase
Upgrade your Harley Davidson Big Twin engine with the S&S Cycle MR103C Chain Drive Camshaft Kit, designed for models from 1999 to 2006. This kit is ideal for modified engines with larger displacement and higher compression, providing significantly more torque and horsepower than standard bolt-in cams. The MR103C is compatible with stock valve springs in 2005 and 2006 models, offering an efficient upgrade option for enthusiasts seeking enhanced performance without extensive modifications. For optimal results, pairing this camshaft kit with a performance intake and exhaust system is highly recommended to maximize power gains.
The kit includes a durable chain drive camshaft, a cam support plate, and a recommended oil pump upgrade to ensure reliable operation. Additionally, a stock hydraulic cam chain tensioner upgrade for 2007 and later models is highly advised to maintain proper chain tension and prevent premature wear. Proper installation and component compatibility are critical; thus, professional installation is recommended.
Designed specifically for select Harley Davidson models, such as the FXDX Dyna Super Glide Sport, FXDXT Dyna Super Glide T-Sport, and Screamin Eagle Softail Deuce, this camshaft kit delivers a noticeable increase in engine performance. Whether you're aiming for more aggressive acceleration or improved overall power, the S&S MR103C kit offers a reliable solution for serious riders looking to upgrade their engine's capabilities.
