MIP have introduced the new X-Duty rear center shaft kit for the Traxxas Unlimited Desert Racer. Made from hardened alloy steel, heat treated to a spring temper for maximum durability and wear, the MIP X-Duty rear center shaft is designed and built to handle any and all driving conditions. It is also tuned to length to ensure the shaft never bottoms out when the chassis flexes resulting in a more durable and wear-resistant shaft than the stock shaft. Its reliability, strength and power allow it to handle any power, including 6S LiPo batteries. The MIP X-Duty rear center shaft is a direct fit without any modifications and utilizes X-Duty couplings and hardware for easy rebuilding.
