TRAXXAS TRX4 Wheel Hex Spacers +6mm TRX4010/12MM by GPM  [TRX4010/12MM]

TRX4 Wheel Hex Offset Adapters

This aluminium wheel hex adapter set is designed for the TRAXXAS TRX4 Trail Crawler, model TRX4010/12MM. By increasing the hex to 12mm (+6mm), the adapters push wheels outward to lessen play at the hub and broaden the track for steadier slow-speed crawling on rough terrain.

The adapters mate with standard TRX4 wheel hex hubs and accept connection to front CVDs and rear drive shafts that take wheel hexes. Fitment is straightforward for builds using the stock wheel mounting layout, and the package includes the necessary fasteners and shims to lock the adapters in place. These parts are intended for model use on TRX4 Trail Crawler vehicles only.

Use these when you want a small handling tweak, to reduce wobble at the wheel-hub interface, or to run wheels with greater backspacing. The increased hex thickness reduces the gap between hex and wheel, helping keep heavier tyres tracking true while crawling.
