TRAXXAS TRX4 Compatible 1.9'' Aluminum Wheel Set - ZSP052 by GPM  [ZSP052]

TRX4 Aluminum Wheel Upgrade

This ZSP052 1.9'' wheel set is an aftermarket aluminum replacement intended for TRAXXAS TRX4 trail crawlers. The kit replaces standard plastic wheels with machined aluminum components to increase rim stiffness and provide external ballast for slow-speed crawling situations.

The supplied kit contains wheel discs, outer and inner rims, plus cap head screws in M2.5x12 and M2.5x8 lengths. Each assembled wheel is listed at 107g, a factor to consider when setting shock preload and choosing tyres, as the extra mass affects bead seating and suspension response.

• 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, chosen to improve durability and maintain consistent rim shape.
• Weight role: single wheel weight ~107g, useful as external ballast to aid traction during technical crawling.

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

Tuning advice: adding heavier aluminum wheels increases unsprung mass which can boost low-speed traction on steep sections but will alter steering feel and suspension dynamics, so retune shock preload and tyre compound as needed.
