Frequently Asked Questions

• Which Traxxas X-Maxx and XRT models does this bearing kit fit? — This complete bearing kit is compatible with the X-Maxx Ultimate, X-Maxx, XRT Ultimate and XRT models. It's specifically designed for the latest-generation X-Maxx platform. However, if you own an earlier X-Maxx model, you may need to source additional upgraded parts for full compatibility, so we recommend checking your model year before ordering.
• Why would I need to replace the bearings on my RC monster truck? — Bearings naturally wear during normal use, causing increased friction and potentially affecting handling precision and responsiveness. Over time, dust and grime can also accumulate in standard bearings, making your truck feel sluggish. This complete kit restores everything to factory-fresh condition, dramatically improving smoothness and performance.
• What are the benefits of blue rubber seal bearings compared to standard bearings? — The blue-seal design keeps dust and grime out of the bearing races, resulting in less maintenance work for you and smoother running over longer periods. These sealed bearings also reduce friction, meaning your truck will feel more responsive and perform more consistently regardless of track or weather conditions.
• Is bearing replacement difficult, or do I need professional help? — With the included identification label and compartmented storage, this kit is designed to make bearing replacement straightforward. The label helps you identify each bearing before installation, and the organised box prevents confusion during the process. If you've done basic RC maintenance before, you'll find this kit very user-friendly.
• Will replacing the bearings improve my truck's top speed? — Whilst bearing replacement won't dramatically increase absolute top speed, it will restore your truck to factory performance specifications and potentially improve acceleration by reducing friction in the drivetrain. More importantly, you'll notice crisper handling and more responsive steering, which translates to better control and more enjoyable driving on any terrain.
• What's the difference between this complete kit and buying bearings individually? — This kit provides everything in one organised package with proper identification, saving you time sourcing individual bearings and ensuring you get exactly what your X-Maxx or XRT needs. The compartmented box and label also make installation much easier and more enjoyable.
