This is the Traxxas Front/Rear Sway Bar Kit for the XO-1 On-Road Car.
The XO-1's fully-adjustable suspension system is even more tunable with the addition of the all new Traxxas front and rear sway bar kit. Pre-assembled links with installed pivot balls make fine-tuning the sway bar stiffness quick and easy. This easy-to-install kit includes “heavy” and “light” sway bars to adjust weight transfer. Installation hardware is included.
