TRAXXAS TRX4 Wheel Hex Conversion 9mm Front 12mm Rear - TRX4010/0912 by GPM  [TRX4010/0912]

Aluminium hex conversion kit for TRX4 crawlers

This accessory is tailored for TRAXXAS TRX4 Trail Crawler owners seeking a simple hex-width swap to refine wheel seating and track width. The front hex changes from 5mm to 9mm while the rear changes to 12mm, shifting the wheels outward to reduce the hub gap and enhance rear stability.

Hardware supplied is intended for direct mating with front CVD joints and rear drive shafts during wheel installation. The kit contains stainless screw shafts, spring steel shims, iron washers, and stainless hex socket screws to secure the adapters and preserve a tight wheel interface. Installation is designed to be straightforward and largely plug-and-play.

Functional advantages:

• Tighten the lateral gap between wheel and hub for improved seating and steering feel.
• Increase rear offset to broaden effective track and improve low-speed crawl performance.
• Enable quick track tuning without replacing wheel hubs or axle components.

Fit notes: inspect CVD and driveshaft clearances after fitting, ensure all fasteners are tightened to avoid loosening during runs, and re-check wheel balance after changing hex sizes.
