TRAXXAS TRX4 Trail Crawler Aluminum Hex Adapters 9mm & 12mm by GPM TRX4010/0912  [TRX4010/0912]

Aluminum hex adapter kit for TRX4

This is an RC-scale accessory designed for TRAXXAS TRX4 Trail Crawler owners who need a straightforward hex-width change for wheel fit and track tuning. The kit replaces the standard 5mm hex with 9mm at the front and 12mm at the rear to move wheels outward, reduce hub-to-wheel gap, and increase rear track stability.

Hardware supplied in the source list supports direct connection to CVD front joints and rear drive shafts when fitting wheels. The package includes stainless steel screws, spring steel shims, iron washers, and hex socket screws to secure the adapters and maintain a tight wheel interface. The adapters are intended for plug-and-play replacement with minimal setup.

Practical roles:

• Reduce lateral gap between wheel and hub to improve wheel seating.
• Widen rear wheel offset to extend effective wheelbase and improve straight-line and low-speed crawling stability.
• Provide a simple tuning option to fine-tune track width without changing wheel hubs or axles.

Installation notes: verify CVD and drive shaft clearance after installation, confirm all supplied fasteners are tightened to avoid loosening during use, and check wheel balance after changing hex widths.
