The Traxxas 9460X Drag Slash Wheelie Bar is an extended rear wheelie bar and mount kit originally developed for the Traxxas Drag Slash drag‑racing truck that helps keep the front end down during hard acceleration and improves straight‑line performance on the strip. it features an extra‑long design with five adjustable height positions and two wheel sizes so you can fine‑tune how the bar engages the surface, plus all the necessary heavy‑duty mounting hardware to fit either a standard or low‑cg chassis for maximum customization and control. this wheelie bar is also popular as a performance accessory for other 1/10 scale 2wd RC trucks to help manage lift and traction during rapid launches or drag runs.
