This GPM component is produced using SLA 3D printing to deliver consistent surface finish and scale detail for Traxxas TRX-4 Scale and Trail Crawler applications. It is intended for use with the Land Rover / Defender Body model 82056-4 and is not compatible with the TRX4 Tactical Unit model 82066-4. Installation requires cutting a precisely shaped aperture in the shell and careful edge preparation to ensure an accurate, flush fitment.
