Overview
The Powerhobby TRX-4 Brass Upgrade Combo is the ultimate weight-and-strength upgrade package for the Traxxas TRX-4 1/10 scale crawler. This comprehensive combo replaces stock plastic steering knuckles, portal covers, C-hubs, and wheel hexes with premium brass components — adding critical low, outboard mass exactly where it matters most for crawling performance.
