These are a modified version of the standard Sliders for Gspeed Chassis V3 Rails. Same stock detentions as the standard V3 sliders but with a Carbon Fiber side rail to Add strength. Some bodies like the Power wagon will tuck into the carbon side rail as well. These are a 3D Printed/ Carbon Fiber Hybrid and the printed portion is available in over 30 colors to match your build. Contact me for if you need a set to match a specific body
