TRX4 Parts & Upgrades

Everything we keep in stock for the Traxxas TRX-4 / TRX-4 Sport (1/10) — spares, brass weight, drivetrain and electronics. Find what broke, fix it, get back out.

  • Every TRX4 spare we stock, grouped so you can find the part that actually fits.
  • Direct-fit replacements and mechanical upgrades for the Traxxas TRX-4 / TRX-4 Sport (1/10).
  • Dispatched from our UK warehouse — in-stock items ship the same working day.

This page lists TRX4 parts only. If your model is a different scale, check the parts page for that chassis — 1/10 and 1/18 parts are not interchangeable.

Not the right chassis?

We keep separate parts pages for each chassis we support - pick yours and see only what actually fits.
