The Traxxas 4975 wheelie bar is a rear‑mounted accessory designed to help keep your RC truck stable during hard acceleration by preventing excessive wheelstands, allowing for smoother, more controlled runs and reducing the chance of flipping over backward, built from durable materials with adjustable height and spacing to fine‑tune performance, and compatible with Traxxas models such as the Traxxas Rustler, Traxxas Slash, Traxxas Stampede, and other similar vehicles that accept the wheelie bar mount for improved power‑on driving control.
