Overview
Upgrade your TRX-4M trail truck with the Traxxas Ball bearing set, transmission, black rubber sealed (TRX9745R). If you're serious about improving the performance and longevity of your 1/18 scale RC crawler, these premium transmission bearings are an essential upgrade. Whether you run your TRX-4M Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150 in muddy terrain, dusty fields, or wet conditions across the UK, quality bearings make a real difference to how smoothly and precisely your model performs. Stock bushings simply can't match the smooth rolling action and durability that precision ball bearings deliver, especially when you're tackling challenging off-road environments.
Black-seal ball bearings represent the pinnacle of bearing technology for RC cars and trucks. They're engineered to offer superior protection from the elements compared to standard blue-seal alternatives, making them the intelligent choice for serious hobbyists and weekend bashers who want their TRX-4M to perform at its best. These bearings significantly reduce friction throughout the transmission, which translates directly into improved efficiency, smoother power delivery, and ultimately better control of your RC trail truck. The tight seal design means less maintenance is required even after running in dirty environments, saving you time and frustration when you return from a muddy trail session.
For RC enthusiasts across the UK looking to get the absolute best performance from their TRX-4M, this bearing set is a no-brainer upgrade. The precision engineering and superior sealing technology ensure that every component of your transmission works together harmoniously, giving you confidence in your model's reliability whether you're navigating a rock garden or blasting across open ground.
Key Features
- Black-Seal Technology — These bearings feature a superior rubber seal design that goes beyond standard blue-seal bearings, providing ultimate protection from dirt, dust, water, and debris. This advanced sealing ensures your transmission stays cleaner for longer and requires significantly less maintenance, which is particularly valuable when running in muddy or wet conditions.
- Reduced Friction and Improved Efficiency — Replacing stock bushings with precision ball bearings dramatically reduces internal friction throughout the transmission. This means smoother power delivery to the wheels, better throttle response, and more precise control of your TRX-4M during challenging trail driving.
- Enhanced Precision and Performance — Ball bearings roll with exceptional smoothness and accuracy compared to bushings, resulting in tighter tolerances and improved overall handling characteristics. Your TRX-4M will respond more predictably to steering and throttle inputs, giving you greater confidence when navigating technical terrain.
- Extended Component Lifespan — The superior sealing and smooth rolling action of these bearings reduces wear and stress on transmission components, helping to extend the life of your entire drivetrain. This means fewer repairs and replacements, saving you money in the long run.
- Less Maintenance Required — The tight rubber seals keep contamination out, which means you'll spend less time cleaning and servicing your transmission. After a muddy trail session, your transmission will stay cleaner and require less intensive maintenance compared to bushing-equipped models.
- Perfect for Dirty Environments — Whether you're running in dusty desert conditions, wet woodland terrain, or muddy farmland across the UK, black-seal bearings are specifically engineered to protect against the elements while maintaining smooth operation.
- Complete Transmission Solution — This set includes six 3x6x2.5mm bearings, providing a complete bearing upgrade for your TRX-4M's transmission system. You get everything needed to fully upgrade your transmission in one convenient package.
Technical Performance
These black-seal ball bearings represent professional-grade engineering designed specifically for 1/18 scale RC trail trucks like the Traxxas TRX-4M. The 3x6x2.5mm sizing is precision-engineered to fit perfectly within your TRX-4M's transmission housing, replacing the factory bushings with dramatically superior rolling elements. The black rubber seal design features a tighter closure compared to blue-seal alternatives, creating a more effective barrier against the ingress of mud, sand, and water. This engineering approach means that even after intense off-road sessions in challenging conditions, your bearings remain protected and continue to roll smoothly. The materials used in these bearings are of the highest quality, featuring hardened steel races and premium-grade ball elements that can withstand the demands of RC trail driving. The six bearings included in this set provide comprehensive coverage of your transmission's critical rolling points, ensuring that friction is minimised throughout the entire drivetrain. For competitive trail driving or weekend bashing with your TRX-4M Ford Bronco, Land Rover Defender, or other TRX-4M variant, upgrading to these bearings is one of the most effective performance enhancements you can make, delivering noticeable improvements in smoothness, efficiency, and longevity.

Frequently Asked Questions
- Will these bearings fit my TRX-4M trail truck? — Yes, these bearings are specifically designed as an accessory part for the entire TRX-4M range, including the Ford Bronco, Land Rover Defender, Chevrolet K10, and Ford F-150 variants. The 3x6x2.5mm sizing is the correct specification for the TRX-4M transmission system.
- What's the difference between black-seal and blue-seal bearings? — Black-seal bearings offer an even tighter seal compared to blue-seal alternatives, providing superior protection from dirt, dust, and moisture. This means better performance in dirty environments and significantly reduced maintenance requirements. If you regularly trail your TRX-4M in muddy or dusty conditions, black-seal is the superior choice.
- How much of a performance difference will I notice? — You'll notice reduced friction throughout your transmission immediately upon installation, resulting in smoother power delivery and more responsive handling. Your TRX-4M will feel noticeably more precise and efficient, particularly noticeable when navigating technical terrain or during sustained driving sessions.
- Do I need any special tools to install these bearings? — Installation requires standard RC hobby tools and mechanical knowledge of your TRX-4M's transmission assembly. If you're not comfortable with transmission work, we recommend consulting your TRX-4M manual or visiting our RC Model Shop store for assistance.
- How often will I need to replace these bearings? — With proper maintenance and care, these quality bearings will last significantly longer than stock bushings. Regular inspection and light cleaning after muddy sessions will help maximise their lifespan, though they typically remain in service for extended periods with minimal degradation.
- Are these suitable for competitive trail racing? — Absolutely. Many serious RC trail competitors choose black-seal bearings as part of their performance upgrade package. The improved efficiency and precision they deliver can provide meaningful advantages in competitive environments.
