Question:
What are the benefits of using a metal differential cup bearing?
Answer: Using a metal differential cup bearing significantly enhances durability and performance compared to plastic alternatives. Metal bearings can withstand higher stress and provide smoother operation, which is crucial for high-speed RC cars. This means you’ll experience better acceleration and handling during races, and your vehicle will have a higher longevity in terms of critical components. -
Question:
How do I install the Metal Differential Cup Bearing?
Answer: Installation of the Metal Differential Cup Bearing is straightforward for those familiar with RC car maintenance. First, disassemble the differential from your model, then carefully remove the old bearing. Replace it with the new metal bearing by ensuring it fits snugly. It's essential to check that everything is aligned properly before reassembling your vehicle to avoid issues while driving. -
Question:
Will upgrading to a metal differential cup bearing affect my car's speed?
Answer: Yes, upgrading to a metal differential cup bearing can positively affect your car's speed. These bearings reduce friction, allowing for smoother operation and better energy transfer.

How often should I replace the differential cup bearings?
Answer: The frequency of replacement for differential cup bearings depends on your usage.

What should I consider when choosing differential cup bearings?
Answer: When selecting differential cup bearings, consider the material, size, and compatibility with your model.

sea jump Differentials Editorial Review
This is a complete set of metal gears for a 1/12 scale vehicle, which includes both front and rear gears. It is compatible with the 12423/12428 Wltoys models. Customers have noted that they had to add grease to the gears as they come shipped dry, but the gears are made of metal. While some customers have reported that the product is not suitable for their model or is too small, others have found it to be a good replacement for stock gears.
