Endurance Series 1.5 Ratio Rocker Arm

With a 1.5 ratio and a 3/8 inch stud mount, this rocker arm is built to provide reliability and precision. Constructed from lightweight 7000 Series Aerospace-grade aluminum, the Endurance Series rocker arms offer maximum strength and durability while contributing to faster RPM gains, being an average of 28 grams lighter than the Race Series. They feature a needle bearing fulcrum and roller tip, a centerless ground trunnion and pin, and a large machined seat. The body construction and lower profile design enhance fitment, particularly under most stock valve covers, and utilize shorter polylocks for improved valve cover clearance. Engineered for extreme conditions, these rocker arms can handle up to .750 inch of valve lift and withstand 750 lbs of maximum open spring pressure. The components are 100 percent CNC machined in the USA, with black oxide coated steel parts and anodized aluminum for superior protection and longevity. Scorpion Racing Products backs these rocker arms with an exclusive lifetime warranty.
