Overview
Replace or refresh your Hot Racing SXTF39W04 wide-track front axle assembly with the Hot Racing +4mm Wide-Track Hardened Steel Replacement Front Axles. CNC-machined from hardened spring steel, these direct replacement axles are designed specifically as the front-axle component of the SXTF39W04 +4mm wide-track set for the Axial SCX24, restoring full wide-track functionality if you've damaged or worn your originals.
If you've ever bent or stripped a stock SCX24 axle, you'll appreciate the strength of these hardened-steel replacements. They handle the increased leverage of the wider stance without complaint and stand up to the abuse of aggressive scale crawling, technical lines, and rough terrain driving.
