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

Aluminium hex adapter set for TRX4 upgrades

This accessory is made for TRAXXAS TRX4 Trail Crawler owners who want a simple hex-width change to refine wheel fit and track behaviour. The kit swaps the stock 5mm hex for 9mm at the front and 12mm at the rear to push the wheels outward, close the hub-to-wheel gap, and boost rear track stability.

The supplied hardware list supports direct mounting to front CVD joints and rear drive shafts when fitting wheels. The kit includes stainless steel screw shafts, spring steel shims, iron washers, and stainless hex socket screws to lock the adapters and preserve a snug wheel interface. Installation is intended to be plug-and-play with minimal setup required.

Practical uses:

• Close lateral gap between wheel and hub to improve seating and reduce side play.
• Increase rear wheel offset to widen effective track and improve straight-line and low-speed crawling stability.
• Offer a straightforward tuning option to adjust track width without changing hubs or axle assemblies.

Installation notes: check CVD and drive shaft clearance after fitting, ensure all supplied fasteners are torqued to avoid loosening in use, and verify wheel balance after changing hex widths.
