Micro Sprint Rear Torsion Arms are built by racers for racers. The RR Arm is built from a solid billet versus being bent as is standard for our competition. Bending causes stress fractures in the aluminum. We spends the time to machine the arms from solid billet eliminating the need for bending producing the strongest arm possible. The rear arms include all hardware and a machined spud that allows your shock end to run bind free! Black anodize and laser etched. Our torsion products fit the popular 7/8″-48 spline found on most Micro Sprints. Available in 4″ and 4-3/8″ inch offset. 4-3/8″ offset used on Farrell Frameworks chassis.
