FAQs about TRX4M Upgrade Parts
1. What are the best first upgrades for a TRX-4M?
The most recommended first upgrades are:
- Servo – The plastic gears of the stock servo are fragile. Upgrade to a metal gear servo for stronger, more precise, and reliable steering.
- Metal Crawler Gears – Replace stock gears with metal ones to prevent wear and breakage under heavy use.
- Wheels & Tires – Upgraded wheels and tires provide better traction and grip, essential for crawling on rocks and loose surfaces.
- Shocks – Smooth out suspension for better control and stability on rough terrain.
- Brass Parts – Add weight in the right places (wheels, knuckles) to improve stability and lowers the center of gravity.
- Driveshafts & Links – Replace stock plastic driveshafts and links to prevent breakage and improve drivetrain durability.
2. Is the Traxxas TRX4M waterproof?
The TRX4M is water-resistant.
Its electronics like the ESC, receiver, and servo are sealed, so It can handle wet surfaces, splashes, and light rainfall without issue.
However, it is not fully submersible. Avoid dunking it in deep water, and always clean and dry it afterward to prevent rust or damage to mechanical parts.
