Traxxas 5136X Differential Oil Kit – 10K/30K/50K Weights for Adjustable Limited Slip

Refine Traxxas performance with the 5136X Differential Oil Kit

The Traxxas 5136X Differential Oil Kit makes it straightforward to adjust the limited-slip action of your sealed gear differential. By selecting different lubrication weights, you can tailor how the diff locks during cornering, which can translate to more controlled steering and faster exits on varying track surfaces. The trio of weights—10,000, 30,000, and 50,000—lets you experiment without replacing the entire differential.

Designed for durability and long-lasting performance, these oils are built to endure the heat and stress of demanding runs. When paired with genuine Traxxas stock and hop-up parts, the kit integrates cleanly into your vehicle's drivetrain, preserving reliability while offering added tuning flexibility. This replacement hardware is intended for use on Traxxas vehicles; please consult your user manual for exact parts listings.

What’s in the kit

• 1 x 10,000 weight differential oil
• 1 x 30,000 weight differential oil
• 1 x 50,000 weight differential oil

How to use and what to expect

• Thicker oils provide more differential locking action, affecting how the wheel pair locks during dynamic turns
• Altering the limited-slip capability can enhance turning performance for faster exit speeds on certain tracks
• Use Traxxas stock and hop-up replacement parts to maximize compatibility and reliability with your vehicle

On the track or in a tight parking lot setup, lighter oils may allow more subtle slip for a smoother ride, while heavier oils can help the diff bite earlier in corners. You can mix weights or switch to a single weight to match track conditions, giving you a practical, controllable way to tune handling without a full drivetrain overhaul.

Compatibility and proper use matter: this kit is designed for Traxxas sealed differentials and works with Traxxas RTR vehicles. For best results, follow the official manual guidance and treat these oils as tuning options rather than guaranteed performance changes.
