Designed for the Traxxas TRX4 Scale and Trail Crawler, these stainless slip-proof treads deliver a durable, scale-oriented surface with a realistic engraved pattern. They are intended for use with the Land Rover / Defender Body model 82056-4 and are not compatible with the TRX4 Tactical Unit model 82066-4. Installation is achieved using the included double-sided tape to ensure a firm adhesive bond without modification to the body.
