TRAXXAS TRX-4 23mm Brass Hex Adapter Precision Kit TRX4010X/23M by GPM  [TRX4010X/23M]

23mm Brass Hex Adapter Technical Overview

This 23mm brass wheel hex adapter set provides a precision-machined brass upgrade for TRAXXAS TRX-4 style trail platforms where increased track width and additional hub mass are required for handling tuning. Each adapter is machined in brass to a 23mm hex dimension, creating a thicker hex profile than standard parts to move wheel offset outward and reduce wheel-to-body gap.

Key hardware included in the kit: Hex Adapter 4pcs, Stainless Steel Screw Shaft M4x2.5x11 4pcs, Shims 5mm 4pcs, 5mm Metal Washer 4pcs, Stainless Steel Hex Socket Screw 20mm 4pcs. Per supplier information the individual adapter mass is approximately 17g each, supplying consistent added weight at each hub for measurable handling effect.

Installation guidance: remove the OEM hex, mount the brass adapter onto the axle, position shims or washers to trim offset as required, and secure with the supplied M4 shafts and 20mm hex socket screws. Verify correct thread engagement and wheel alignment after fitting; the wider hex may necessitate minor wheel trim or spacer variation depending on wheel geometry and tyre clearance.

Tuning considerations: the 23mm profile increases track and unsprung mass at each hub, which typically improves low-speed composure and reduces lateral tip tendencies. Adjust shock damping and spring rate to accommodate the increased hub mass and retain desired suspension response.

A complete hardware kit designed to widen track and add repeatable hub weight on TRX-4 based trail rigs while maintaining straightforward fitment.
