This is an Extended Body Mount Kit with Secure-Loc Caps for the Traxxas Monster Trucks. Pro-Line continues to innovate with more must-have accessories for your Monster Truck. The all-new Pro-Line body mount kit includes adjustable body mounts so you can fit any body on your truck perfectly! But, the Pro-Line Engineers did not stop there. Instead of just using the same old flimsy body clips that always get lost and bent, the Pro-Line Extended Body Mount kit includes a revolutionary screw on body mounting system for a strong and secure mount every time. No more getting stabbed in the finger by those nasty clips! Just screw down the included setscrew into the body mount, place the O-Ring over the setscrew and mount your body as you normally would. This new Extended Body mount kit adds safety, security and styling with Pro-Line's innovative screw on body mounting system!
