These 9mm brass wheel hex adapters are CNC style machined for TRAXXAS TRX4 Trail Crawler applications to increase lateral track and rotational inertia, improving low speed traction and vehicle stability. Each adapter measures 9mm thick, approximately 4mm thicker than the original hex, with an individual mass of about 6g as supplied.
The increased hex thickness reduces the lateral wheel to hub gap on TRX4 hubs and provides an outboard offset without changing suspension geometry. The component set is supplied with the required hardware for direct replacement of stock hexes where the TRX4 wheel hubs accept 9mm hex thickness.
Standard installation involves wheel removal, replacement of factory hex with the brass adapter, and refitting with the supplied fasteners while confirming clearance and seating. Periodic inspection of fasteners and wear points is recommended for sustained upgrade performance.
