The Pro-Line Supersonic Speed Run Body is an incredibly aerodynamic body option that makes it easier to convert a Traxxas Slash 4x4 into a speed runner! The speed run scene is gaining momentum and the Supersonic body will let you take your Slash 4x4 (or other modified SC-based trucks) and jump right in.

Belted tires are a must for going fast and the Reaction HP SC tires, or Avenger HP 1:8 tires pair perfectly with the Supersonic body. Pro-Line Extended Body Mounts are used to slam the body as low as possible and wide offset hexes to add even more high-speed stability to your build and to fill out the wheel wells.

Supersonic setup shown with the following parts (sold separately):

  • Slash® 4x4 with Aluminum 17mm Wheel adaper set (TRA6856X)
  • Pro-Line Reaction HP SC BELTED tires (PRO10170-203)
  • Pro-Line Raid 6x30 Removable Hex SC Wheels (PRO2785-03) using 2.8" 17mm Hex Adapers (PRO6336-00)
