S&S Cycle 1984+ BT 1.725 To 1 Ratio Rocker Arm Set

This kit from S&S Cycle gives you a set of four rocker arms, two for the front cylinder and two for the rear, designed for 1984 and later Harley-Davidson Big Twin engines. You'll get the performance rocker arms with a 1.725:1 ratio, which can help improve valve lift for better engine breathing, especially when paired with high-lift camshafts. These are well-built components meant to handle the rigors of performance engine work.

What sets these rocker arms apart is their construction. They feature 3/4 inch long bushings, offering 50% more support area compared to standard 1/2 inch bushings. This increased support helps reduce stress on the valve train. The rollers used in these arms are extremely durable and are designed to minimize side thrusting on the valve stems, a common concern with high-lift cams. This design contributes to superior wear and fatigue resistance, ensuring they hold up even under demanding conditions.

This set is a solid option for builders looking to enhance the performance of their Big Twin engine. While these are performance rockers, they are designed to fit a range of Harley-Davidson models, including popular bikes like the Road King, Electra Glide, and Street Glide. Always refer to the manufacturer's installation instructions for specific details on fitting these to your particular motorcycle.
