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

Precision hex adapters for TRX4 wheel tuning

This kit provides a no-fuss hex-width conversion for TRAXXAS TRX4 Trail Crawler rigs, intended to tighten wheel fit and fine-tune track width. The front side converts 5mm to 9mm and the rear converts 5mm to 12mm to move wheels outward and reduce the hub-to-wheel gap.

Included hardware supports direct connection to front CVDs and rear drive shafts during wheel installation. Components listed include stainless screw shafts, spring steel shims, iron washers, and stainless hex socket screws to secure the adapters and maintain a firm wheel interface. The adapters are intended for straightforward replacement with minimal alignment work.

Key benefits:

• Reduce side clearance between wheel and hub for a firmer seating.
• Widen rear offset to lengthen the effective track and aid stability when crawling slowly.
• Provide a simple tuning route to change track width without swapping hubs or axles.

Fitment tips: confirm CVD and driveshaft clearance post-install, torque supplied fasteners to specification to prevent loosening, and check wheel balance after changing hex widths.
