WPL C94 Upgrades – Complete Guide (2026)

The WPL C94 RTR UAZ-469 is one of the most popular WPL platforms because it’s:

  • Affordable

  • Extremely mod-friendly

  • Capable of major performance upgrades

If you’re wondering which upgrades actually make a difference (and which don’t), this guide breaks it down by priority, not hype.


Stage 1: Must-Have Reliability Upgrades

These upgrades fix the known weak points of the stock C94.

🔧 Metal Upgrade Kit (Highly Recommended)

The stock plastic drivetrain works — until you:

  • Add weight

  • Add torque

  • Drive outdoors regularly

What metal upgrades improve:

  • Adds weight > Lowers the CG > Reduce roll over tendency

  • Axle durability

  • Drivetrain lifespan

Who should install this:
✔ Outdoor drivers
✔ Anyone planning further upgrades
✔ Anyone who hates fixing broken plastic parts


🔧 17g DMG Metal Gear Servo

The stock servo is functional but risk breaking the plastic gears.

A metal gear servo gives:

  • Stronger steering under load

  • Better control on uneven terrain

  • 99% less risk of breaking gear during operation

This is one of the highest value upgrades per dollar.


Stage 2: Performance & Driving Experience Upgrades

This is where the C94 starts to feel like a different vehicle.

⚙️ Dual-Speed Gearbox

The dual-speed gearbox adds:

  • Low gear for crawling

  • High gear for trail driving

Instead of compromising between speed and torque, you get both!

Best for:
✔ Trail runs
✔ Mixed terrain
✔ Realistic driving experience


Stage 3: Immersion & Realism Upgrade (Most Popular)

🔊 RES-V3 Sound ESC System

👉 https://www.wpl-rc.com/products/r-e-s-v3

This is the upgrade that changes how the C94 feels, not just how it drives.

What RES-V3 adds:

  • Engine sound synced to throttle

  • Integrated ESC + receiver + sound

  • Brake, idle, and acceleration sound

Most C94 owners say:

“This is the upgrade that made my WPL feel alive.”


Recommended Upgrade Order (Simple Answer)

If you’re upgrading gradually:

1️⃣ Metal upgrade kit
2️⃣ Metal gear servo
3️⃣ Dual-speed gearbox
4️⃣ RES-V3 sound system

If you want maximum impact fast:

  • Metal upgrades + RES-V3


Final Thoughts

The WPL C94 is popular because it scales with you:

  • Start stock

  • Upgrade over time

  • Build your own version

This guide focuses only on upgrades that actually improve ownership, not unnecessary mods.


👉 Pro tip:
Most C94 owners upgrade in stages. Don’t rush — enjoy the build.
