This 16pcs polyurethane skid plate upgrade set is an aftermarket RC-scale accessory designed for the TRX-4 platform, supplied by GPM (TRX4ZSP16A). The kit focuses on visual realism and chassis protection for scale trail crawling models, providing front and rear skid plate supports, main skid plates, and the fastening hardware needed for installation.
The components are moulded in high-grade polyurethane for flexibility and abrasion resistance typical for scale trail use, and they are described as decorative parts that integrate with the vehicle's subframe to enhance a realistic underbody look while offering low-profile protection during slow-speed rock crawling.
Installation is intended for model-level modification of Traxxas TRX-4 scale vehicles and uses the included M3.0x6 round head hex screws; basic fitting requires common RC tools such as a hex driver and standard workshop practice for removing and refitting body or chassis parts.
For builders seeking a scale visual upgrade and modest underbody protection on TRX-4 scale crawlers, this GPM polyurethane skid plate kit offers a straightforward aftermarket option that blends styling with functional reinforcement for slow-speed trail use.
