Over-engineered, track tested, and made in the USA, Scorpion Endurance Series Rocker Arm Kits for small block Chevy offer no-compromise performance. Shaft rockers are stronger and provide more stable valve timing versus traditional stud mount rocker arms. Precision CNC-machined to exact specifications, each rocker has a fully radiused body with a needle bearing fulcrum and a 4140 heat-treated steel stand. These full-roller arms weigh just 120 grams each, yet are still able to handle the stress of a racing environment.
Scorpion Endurance Series Rocker Arm Kits are available for 1955-99 small Chevy engines and come in 1.5, 1.6, 1.7, 1.5/1.6, and 1.6/1.7 ratios. They’re sold in sets of 16 and include all mounting hardware and assembly lube.
