Traxxas TRX-4 Spares & Upgrades

Keep your crawler performing with our Traxxas TRX-4 spares. Whether you run a Defender, Bronco, Sport or Tactical, you’ll find genuine Traxxas replacement parts plus proven upgrades from RC4WD, Fastrax, MIP and RC Overhaul. From portal axle gears, housings and knuckles to links, driveshafts, shocks, diffs and bearings, we’ve got the wear items and hop-ups you need. Replace scuffed bumpers, body posts and wheel hexes, refresh tyres and foams, or add scale hardware and LED options. Use the filters to drill down by model, brand and part type, or search by Traxxas part number for a direct swap. Go heavy-duty with MIP steel driveshafts, tighten tolerances with RC Overhaul bearing kits, and add scale realism with RC4WD accessories. Fastrax offers great-value tools and aluminium hop-ups for durability and looks. With large stocks ready to ship and next-day delivery available across the UK, you can get back on the trail fast.
