This is an RC-scale stainless steel side step set designed for the Traxxas TRX-4 Defender, supplied by GPM as TRX4ZSP31. The kit is a decorative scale accessory that adds realistic side-step detail and corrosion resistance for outdoor trail use on scale crawlers.
The package provides the parts needed to add the side steps to a TRX-4 Defender body: side steps 10pcs, screws 4pcs, locknuts 4pcs. The components are finished in stainless steel to resist rust and keep a consistent appearance after field use.
Installation overview: the set uses the supplied screws and locknuts to secure the side steps to compatible mounting points on the TRX-4 Defender body or scale rocker panels. Basic hand tools are sufficient, and the parts are intended to preserve scale look without modifying drivetrain or suspension components.
Tuning and role: this accessory focuses on scale appearance and durability rather than performance changes; it can complement other scale upgrades and help protect lower body edges during trail driving.
For TRX-4 Defender owners seeking a stainless, rust-resistant side-step aesthetic, this GPM TRX4ZSP31 kit delivers a compact, hardware-included option to upgrade scale detail.
