Overview
Maximize stability, tire fitment, and durability on your Traxxas TRX-4 with the Hot Racing +10mm Wide Track S2 Hardened Spring Steel Portal Drive Stub Axles. Each side of the vehicle gains 10mm of additional track width, dramatically improving stability over rough terrain, increasing steering clearance, and opening up a much wider range of tire options.
S2 hardened spring steel construction delivers the bulletproof durability that aggressive TRX-4 driving demands, while the blue-anodized aluminum +10mm spacers provide a clean visual upgrade that complements the wider stance.
