The Edelbrock Torque Arm is a non-adjustable arm which features strong tubular construction and a polyurethane front bushing to reduce wheel hop caused by excessive flex under hard acceleration and cornering. It also features a steel adjuster sleeve and spherical ball rod ends on the lower tube, allowing easy pinion angle adjustments without removal. The arm is made of steel with a black powder coated finish for more durability. It only fits models with GM corporate 10-bolt differential and torque arm lips facing away from the driveshaft.
