Upgrade your engine's performance and reliability with the S&S Cycle Rocker Arm Guardian Kit. This comprehensive kit provides all the necessary components to reinforce your valve train and ensure optimal oiling, especially when running high-lift cams. Built with premium materials and advanced engineering, the S&S Rocker Arm Guardian Kit is a must-have for any serious motorcycle enthusiast.

Description

The S&S Cycle Rocker Arm Guardian Kit is designed to replace worn or damaged OEM components with stronger, more durable performance parts. The kit includes high-performance roller rocker arms forged from 8620 steel, providing increased strength and reduced wear on the valve train. The improved rocker geometry is specifically designed for high-lift cams, and the extended bushings offer 50% greater lifespan between rebuilds. The kit also includes hardened and surface-ground rocker arm shafts, along with a high-strength head bolt kit made from heat-treated 8640 steel with an ultimate tensile strength of 200,000 psi, offering a 14% increase in strength over stock head bolts. The kit is compatible with stock or S&S CNC heads. Oil is strategically sprayed directly onto the valve springs, preventing overheating and potential valve failure, a common issue with stock rockers.
