Info

These full-roller Stainless Steel rockers incorporate an exceptional lightweight design that provides plenty of clearance for large diameter springs. Manufactured from premium quality 15-5 PH stainless steel, a superior alloy high in Nickel and Chromium, this rigid material provides high yield strength to help resist deflection and has extraordinary fatigue resistance.

Features full-cage friction reducing needle bearings. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to resist the severity of racing and to minimize "scrubbing". Each rocker body is hand-polished, assembled and carefully inspected to provide our customers with some of the finest quality rocker arms available to the racing and performance industry.
