Frequently Asked Questions

• What size bearings do I need for my Traxxas RC car? — The TRX5120 bearings are 12x18x4mm and are compatible with numerous Traxxas models including the 4TEC 3.0, Ford Fiesta ST Rally, Slash Ultimate 4x4, Stampede 4x4 HD, TRX-4 range and Nissan Pathfinder. Check your vehicle's manual or parts diagram to confirm the correct bearing size for your specific model, as different vehicles may use different bearing sizes.
• Why should I upgrade to sealed bearings? — Sealed bearings keep dust and grime out of the bearing races, reducing maintenance requirements and keeping your vehicle running smoother with less friction. This is especially important if you drive your RC car in dirty or dusty environments, as open bearings quickly accumulate contaminants that cause wear and degraded performance.
• How often should I replace my bearings? — With proper maintenance and sealed bearing protection, quality bearings can last hundreds of hours of driving. Replace them when you notice reduced smoothness, increased resistance, or if they've been subjected to water, mud or excessive dirt exposure. Regular inspection during maintenance sessions will help you identify bearings that need replacement before they cause handling issues.
• Are these genuine Traxxas parts? — Yes, the TRX5120 is a genuine Traxxas OEM bearing part number (5120), manufactured to Traxxas specifications and quality standards. When you purchase from RC Model Shop, you're guaranteed authentic Traxxas components with full compatibility and warranty support.
• What's the difference between sealed and open bearings? — Sealed bearings feature rubber or metal shields that protect the internal bearing races from dust, moisture and dirt, significantly extending bearing life and maintaining smooth operation. Open bearings offer slightly lower friction initially but quickly accumulate contaminants, especially in off-road environments, leading to increased wear, friction and degraded performance.
• Can I use these bearings on any Traxxas vehicle? — The 12x18x4mm size is compatible with many Traxxas models, but not all. Always verify the correct bearing size for your specific vehicle using the parts list or manual. Other sizes like 12x21x5mm and 15x26x5mm exist for different Traxxas applications, so checking compatibility before ordering is essential.
