In the past, widening the front of your Traxxas Rustler and Stampede to match the width of the rear required some custom fabrication that required quite a bit of time and resources. RPM now offers a set of wide, front suspension arms that extend the front width to match that of the rear. This system does require you to purchase another set of front wheels and bolt them to the back as well as new turnbuckles, but no additional fabrication is needed.
Available in black, green or blue. A screw kit is also available for the XL-5 version vehicles.
