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

Aluminum Wheel Hex Adapters for TRX4

This is an RC-scale aluminum wheel hex adapter set produced for the TRAXXAS TRX4 Trail Crawler platform, supplied by GPM as 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 to widen effective track for improved stability at low speeds and during technical crawling.

The adapters are designed to interface directly with standard TRX4 wheel hex hubs and mate with front CVDs and rear drive shafts that accept wheel hexes. Installation is plug-and-play for builders who use the stock wheel mounting pattern, and the package includes the necessary fasteners and shims for a secure fit. Because these are RC-scale accessories, they are intended only for model use on TRX4 Trail Crawler vehicles.

Use these adapters when you need a modest wheel offset to tune handling, reduce wheel wobble at the hub, or slightly extend wheelbase by selecting wheels with greater backspacing. The added hex thickness narrows the gap between hex and wheel, which can help stabilize heavy tires and reduce lateral slop while crawling.
