Compatible with TRX4 Trail Crawlers 1.9'' Aluminum Wheel Set - ZSP052 by GPM  [ZSP052]

Machined Aluminum Wheels for TRX4

The ZSP052 1.9'' wheel set is an aftermarket aluminium replacement made for TRAXXAS TRX4 trail crawlers. The kit swaps out plastic components for machined aluminium parts to strengthen the rim and provide external ballast to aid traction on steep or technical trails.

According to the source, the kit includes wheel discs, outer and inner rims, and cap head screws in M2.5x12 and M2.5x8 sizes. Each assembled wheel is listed at 107g, which will influence suspension tuning and tyre selection; factor that weight into shock preload and ride height settings.

• 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, selected to improve durability and preserve rim roundness under load.
• Weight role: single wheel weight ~107g, acting as external mass to help traction during low speed crawling.

Fitting notes: use the supplied M2.5 cap head screws for assembly, confirm threads are engaged and avoid excessive torque to prevent damage. When installing tyres, check bead seating and clearance relative to TRX4 axle housings and wheel hexes; the source does not list additional adapters.

Handling note: heavier aluminium wheels change unsprung mass and can improve static grip, but steering and suspension response will differ; adjust shock settings and tyre compound to suit the added mass.
