Overview
Add 18mm of track width per side to your Axial SCX10, SCX10 II, or Wraith Crawler with the Hot Racing 18mm Wheel Hub Extensions. CNC-machined from aluminum and built with a 12mm hex output, these extensions provide a sweet-spot width increase between the 15mm and 20mm options — wide enough for noticeable stability gains, narrow enough to avoid most body and fender clearance issues.
Slide them over the stock axles, secure with the included screw pins, and lock in your wheels with the long aluminum wheel nuts. A clean, simple, and effective scale-crawler upgrade.
