Product Details

When you're looking to get more out of your Harley-Davidson's engine, this valve spring kit from S&S Cycle is what you need. This kit includes everything to replace your stock valve springs: valve keepers, top and bottom collars, the springs themselves, shims, and chromoly forged retainers. It's designed to work with cams up to .650 inches of lift, making it a solid option for performance builds on a wide range of Harley-Davidson models, including popular bikes like the Dyna Super Glide, Street Glide, and Heritage Softail.

S&S Cycle builds these springs from ultra-clean, high-silicon Kobe alloy wire. After forming, they're micro shot peened and nitrided. This process helps them withstand the stresses of higher lift cams and more aggressive riding. The conical single wire design is a proven performer, and the included 9-degree locks are CNC machined for a precise fit with the chromoly forged retainers. This attention to detail means you're getting a well-built kit that's ready for the demands of an upgraded engine.
