TRAXXAS GT4 TEC 2.0 Wheel Hex Upgrade 8mm +1mm with Brake Disk - GT010D+1MM by GPM  [GT010D+1MM]

8mm aluminium +1mm wheel hex assembly with brake disk

The GT010D+1MM hex assembly is an aluminium +1mm wheel hex supplied with brake disks for TRAXXAS GT4 TEC 2.0 4WD applications. It widens the track and tidies wheel fitment to provide crisper turn-in and more predictable chassis handling during setup and cornering.

Included items and reference: brake disk - 2 pcs, 2x10 pin - 2 pcs, Manual number: 8356. The hex functions as the mechanical junction between wheel and axle and features a machined swirl ring on the outer face for a refined appearance.

Design notes: the outer ring includes a swirl engraving for visual appeal and the hub is produced at 8mm thickness compared with the common 7mm, which increases lateral track and shifts roll couple and stability. Due to the larger outer diameter, the kit will not work with the stock brake caliper without verifying clearance.

Fitment guidance: installing these hexes alters wheel offset and track width so expect nuanced changes in handling; check axle pin retention and thread engagement, inspect wheel runout post-fitment, and use the offset change as a tuning parameter to refine chassis balance.
