Product Details

When you're rebuilding the top end of your 1984 and later Big Twin Harley-Davidson, getting the valve train geometry just right is crucial for performance and longevity. This rocker arm assembly from S&S Cycle is designed to help you achieve that. It features a 1.625 to 1 ratio, which means for every unit of movement at the pushrod, the rocker arm moves the valve 1.625 units. This updated ratio can help improve valve lift and timing compared to stock components.

S&S Cycle is a well-known name in performance Harley-Davidson parts, and this rocker arm assembly is built to their standards. It's a solid option for riders looking to refresh their engine or make modifications. The assembly fits a wide range of Big Twin models from 1984 through 2016, including popular bikes like the Road King, Electra Glide, and Street Glide. Ensuring you have the correct ratio and well-made components is key to a healthy engine build.
