TRAXXAS TRX4 Precision Hex Adapter Kit 9mm/12mm - TRX4010/0912 by GPM  [TRX4010/0912]

Machined hex adapter kit for TRX4 platform tuning

This kit provides CNC-style aluminium hex replacements engineered to change the stock 5mm interface to 9mm at the front and 12mm at the rear for TRAXXAS TRX4 Trail Crawler setups. The intent is to shift wheel offset outward, reduce hub-to-wheel clearance, and improve rear track stiffness for low-speed stability.

All supplied fasteners and hardware are specified to mate directly with front CVD joints and rear drive shafts. The contents include stainless screw shafts, spring steel shims, iron washers, and stainless hex socket screws to ensure secure clamping and consistent wheel engagement. The adapters are designed for straightforward installation and precise fitment control.

Design focus:

• Improve wheel-to-hub contact by closing lateral gap and limiting radial play.
• Increase rear offset to broaden track width and enhance crawling posture.
• Offer a simple, durable method to adjust track without axle or hub replacement.

Technical notes: verify CVD and shaft clearances for your axle geometry, ensure all hardware is torqued to recommended settings to prevent loosening, and re-check wheel balance after converting hex sizes.
