TRAXXAS GT4 TEC 2.0 hex + brake disk by GPM GT010D+1MM  [GT010D+1MM]

Aluminum +1mm hex with brake disk

This GPM GT010D+1MM aftermarket accessory is an RC-scale aluminum +1mm hex set that includes brake disks, designed for TRAXXAS GT4 TEC 2.0 4WD configurations. The parts are intended to widen the wheeltrack and refine wheel mounting for smoother turning and more predictable chassis response during cornering and tuning sessions.

Included items and reference: brake disk - 2 pcs, 2x10 pin - 2 pcs, Manual number: 8356. The hex assembly serves as both a mounting interface between wheel and wheel shaft and as a cosmetic ring with a machined swirl pattern on the outer face.

Design notes: the outer ring carries a swirl engraving for a modern metallic look, and the hub body is produced at 8mm thickness compared with a typical original 7mm, which increases lateral track width and affects roll couple and stability. Because the overall diameter is enlarged, this kit is not compatible with the original brake caliper and will require confirmation of clearances before fitment.

Installation and tuning role: fitting these hexes alters wheel offset and track width, so expect small changes in handling; verify axle pin retention and thread engagement, check wheel runout after installation, and use the change as a tuning parameter for steadying chassis balance rather than as a primary performance upgrade.
