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

12mm Hex Adapter Set for TRX4 Trail Crawler

This is an RC-scale aluminum wheel hex adapter set for the TRAXXAS TRX4 Trail Crawler platform, model TRX4010/12MM. The adapters increase the hex thickness to 12mm (+6mm over standard), moving wheels outward to reduce play between hub and wheel and widening the effective track to help stabilize the truck at low speeds and on technical lines.

The adapters are machined to interface with standard TRX4 wheel hex hubs and pair with front CVDs and rear drive shafts that accept wheel hexes. Installation is plug-and-play for builders using the stock wheel mounting pattern, and the package includes the fasteners and shims needed for a secure fit. These accessories are intended for model use on TRX4 Trail Crawler vehicles only.

Fit these adapters when you need a modest offset to tune handling, reduce wheel wobble at the hub, or run wheels with more backspacing. The thicker hex narrows the gap between hex and wheel, which helps stabilise heavy tyres and cut lateral slop while crawling.
