TRAXXAS TRX4 TRAIL CRAWLER 1.9'' Aluminum Wheel 15pcs by GPM ZSP052  [ZSP052]

Aluminum Wheels for TRX4 Crawlers

This GPM ZSP052 wheel set is an aftermarket 1.9'' aluminum replacement intended for TRAXXAS TRX4 trail crawlers. The kit replaces standard plastic wheels with machined aluminum components to add rigidity and serve as external ballast where needed during slow-speed crawling.

Kit contents supplied in the source include wheel discs, outer and inner rims, and cap head screws sized M2.5x12 and M2.5x8. Each assembled wheel is listed with a mass of 107g which can influence suspension setup and tyre seating; keep that mass in mind when tuning shock preload and tyre choice.

• Included parts: Wheel Disc 2pcs, Outer Rim 2pcs, Inner Rim 2pcs, Cap Head Screw M2.5x12 2pcs, Cap Head Screw M2.5x8 7pcs.
• Material: aluminum construction as noted in the source, used to increase durability and provide consistent rim shape.
• Weight role: single wheel weight ~107g, useful as external weight to help traction in crawling situations.

Installation notes: use the supplied M2.5 cap head screws to secure the rims and discs, verify thread engagement and avoid over-torquing to prevent stripping. When fitting tyres, check bead seating and rotor clearance with the TRX4 axle housings and wheel hexes; no additional adapters are specified in the source.

Tuning role: heavier aluminum wheels change unsprung mass and can improve slow-speed traction on steep sections, but expect slightly altered steering feel and suspension response; adjust shock preload and tyre compound accordingly.
