This is an Extended Body Mount Kit with Secure-Loc Caps for the Stampede 4x4. Pro-Line continues to innovate with more must-have accessories for your 1:10 Monster Truck. The all-new Pro-Line body mount kit includes adjustable body mounts so you can fit any body on your truck perfectly. Instead of the same old flimsy body clips that always get lost and bent up, the Pro-Line Extended Body Mount kit includes a revolutionary screw-on body mounting system for a strong and secure mount every time. 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, but with the added safety, security and styling of Pro-Line's innovative screw-on body mounting system.
