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

Hex adapter upgrade for TRX4 wheel tuning

This aftermarket kit suits TRAXXAS TRX4 Trail Crawler drivers who need a simple hex-width adjustment to improve wheel seating and track behaviour. It converts the standard 5mm hex to 9mm at the front and 12mm at the rear, moving wheels outward to reduce the hub-to-wheel gap and strengthen rear track stability.

The hardware supplied supports direct attachment to front CVDs and rear drive shafts when mounting wheels. Included items are stainless steel screw shafts, spring steel shims, iron washers, and stainless hex socket screws to hold the adapters and ensure a tight wheel interface. The design aims for minimal setup during swap-over.

Use cases:

• Reduce lateral play between wheel and hub for a firmer wheel seating.
• Extend rear wheel offset to widen track and aid straight-line and low-speed crawling.
• Allow easy track-width tuning without changing hubs or axle hardware.

Fitment advice: check CVD and shaft clearances after installation, secure all supplied fasteners to prevent loosening during use, and confirm wheel balance after changing hex widths.
