Question 1

Will this driveshaft directly replace the stock plastic one on my Traxxas vehicle, and how do I know it will fit?**

Accepted Answer

Yes, it's designed as a direct, bolt-on replacement for specific Traxxas models. To ensure a perfect fit, please check the product number (6855) against the official Traxxas compatibility chart for your vehicle (e.g., Slash 4x4 VXL, Hoss, Maxx). Overwhelmingly, reviewers praise its perfect fit and easy installation, often stating it "dropped right in with no modifications needed."

Question 2

Is the aluminum construction and higher price tag really worth it compared to the stock part?**

Accepted Answer

For drivers who have experienced broken plastic driveshafts—especially with 4x4, high-torque, or heavy-duty use—the upgrade is consistently described as "essential" and a "permanent fix." The 6061-T6 aluminum eliminates a common weak point. If you haven't broken the stock part, it's a preventative upgrade. The value comes from increased durability and peace of mind during aggressive bashing.

Question 3

I've seen comments about screws coming loose. Are any special steps required for installation?**

Accepted Answer

A small but notable number of experienced users on forums recommend applying a drop of **blue (medium-strength) threadlocker** to the set screws during installation. This prevents them from vibrating loose over time and ensures a permanent, reliable connection. It's a simple, one-time step that guarantees optimal performance.

Question 4

What should I expect regarding the appearance of the blue-anodized finish over time?**

Accepted Answer

The anodized blue finish is durable but not indestructible. As with any metal part in an RC car, you can expect normal cosmetic scratches and wear from debris, rocks, and general use. Many users note it still "works perfectly" even after getting scuffed. Buy this part primarily for its mechanical upgrade; consider the color a great-looking bonus.

Question 5

Who is this upgrade most suitable for, and is it necessary for a beginner?**

Accepted Answer

This upgrade is ideal for **intermediate to advanced users** who push their vehicles hard, run with more powerful motors, or have repeatedly broken the stock plastic driveshaft. For a beginner or casual driver using a stock vehicle on milder terrain, the original part may be sufficient. It's a highly recommended upgrade when you're ready to enhance durability for more intense driving.
