Traxxas Ball bearing kit, stainless steel, Slash VXL/Bandit VXL/Stampede VXL/Rustler VXL (complete) TRX3788X

Overview

The Traxxas Ball Bearing Kit in stainless steel (TRX3788X) is an essential upgrade for owners of 2WD VXL RC short course trucks including the Slash VXL, Bandit VXL, Stampede VXL, and Rustler VXL models. This comprehensive bearing replacement kit is specifically engineered to boost performance and dramatically reduce maintenance requirements, making it an ideal choice for RC enthusiasts who want to extend the lifespan of their vehicles whilst maintaining peak operating efficiency. Whether you're a weekend basher enjoying your brushless RC truck in British weather or a serious racer looking to optimise your setup, this stainless steel bearing kit delivers the durability and performance enhancement you need.

Designed for UK RC car enthusiasts who take their hobby seriously, this bearing kit addresses one of the most common wear points in any ready-to-run RC vehicle. By replacing the standard factory bearings with high-quality stainless steel alternatives, you're investing in longevity and reliability that really makes a difference when you're running your RC model in wet conditions typical of the British climate. The complete kit means you have everything needed for a full bearing swap without having to source individual components separately, saving both time and money compared to purchasing bearings piecemeal.

What sets this kit apart from standard bearing upgrades is the thoughtful engineering that goes into every aspect of the product design. The inclusion of high-quality black seals ensures ultimate protection from the elements, meaning you can take your Slash VXL or Bandit VXL out in damp conditions without worrying about water ingress causing rust or performance degradation. For RC hobbyists in the UK dealing with rain, mud, and challenging outdoor terrain, this level of protection is invaluable.

Key Features

• Stainless steel construction — The bearings are manufactured from premium stainless steel rather than standard steel, which provides superior corrosion resistance and maintains performance even when exposed to moisture, water, and humid conditions that are common during RC activities in the UK.
• High-quality black seals — Each bearing features high-quality black seals that offer ultimate protection from the elements, dirt, and water ingress, which means significantly less maintenance is required in dirty and wet environments compared to unsealed bearings.
• Long-lasting performance in wet conditions — The combination of stainless steel and sealed design ensures your RC truck maintains smooth, responsive handling even after exposure to damp weather, puddles, and wet grass, which is particularly important for UK-based RC car enthusiasts.
• Individual compartments with identification labels — The bearing kit arrives in a specially organised box with individual compartments for each bearing size, plus a handy label that helps you measure and identify each part, making installation straightforward and preventing confusion during assembly.
• Complete kit for 2WD VXL models — This is a fully comprehensive bearing replacement kit designed specifically for Traxxas 2WD VXL short course trucks, meaning you receive every bearing needed for a complete swap on models like the Slash VXL, Bandit VXL, Stampede VXL, and Rustler VXL without purchasing additional components.
• Reduced maintenance requirements — By upgrading to sealed stainless steel bearings, you'll spend less time cleaning and maintaining your RC model and more time enjoying it, as the superior sealing and corrosion resistance mean bearings stay in better condition for longer between services.

Technical Performance

This stainless steel bearing kit is engineered specifically for the drivetrain and chassis specifications of Traxxas' 2WD VXL brushless short course truck range. The bearing upgrade represents a significant enhancement to the drivetrain quality of these ready-to-run RC vehicles, which come standard with conventional bearings that can wear and corrode when exposed to wet conditions. The stainless steel material used in this kit offers exceptional corrosion resistance whilst maintaining the precise tolerances required for smooth, efficient power transmission from the motor to the wheels. The black seals incorporated into each bearing design prevent water, dirt, and moisture from penetrating into the bearing races, which would otherwise cause friction increase, noise, and eventual bearing failure. This is particularly important for RC enthusiasts in the UK who regularly run their brushless RC trucks in damp outdoor environments. The individual compartments within the storage box serve not just an organisational purpose but also protect the bearings from contamination before installation. For VXL models equipped with the Magnum 272R transmission, users should note that two additional 10x15x4 bearings are required to complete a full bearing swap, as these transmissions feature a slightly different bearing configuration than the standard VXL setup.

What's in the Box

• Complete set of stainless steel ball bearings sized for Traxxas 2WD VXL short course trucks
• High-quality black seals integrated into each bearing
• Organised storage box with individual compartments for each bearing size
• Identification label sheet for bearing measurement and part identification

What You Need to Complete

• For VXL models with Magnum 272R transmission: two additional 10x15x4 stainless steel bearings (not included in the standard kit)
• For 4WD trucks with Extreme HD parts kit installed: 5120A bearings (x2) and 5117A bearings (x2) in addition to this kit, as Extreme HD components utilise different bearing specifications

Frequently Asked Questions

• Which Traxxas VXL models does this bearing kit fit? — This bearing kit (TRX3788X) is designed to fit all 2WD VXL brushless short course trucks in the Traxxas range, specifically including the Slash VXL, Bandit VXL, Stampede VXL, and Rustler VXL models. It is not compatible with 4WD versions or models equipped with Extreme HD upgrade kits without additional bearings.
• Will this bearing kit work with my Slash Extreme HD VXL? — This kit is compatible with Slash Extreme HD VXL models, though you should verify compatibility with your specific variant. For 4WD trucks with Extreme HD parts installed, additional bearings (5120A x2 and 5117A x2) are required, as Extreme HD components use different bearing specifications than standard VXL trucks.
• Why upgrade to stainless steel bearings for my RC truck? — Stainless steel bearings offer superior corrosion resistance compared to standard steel bearings, which is essential if you regularly run your RC car in wet conditions typical of the British climate. They also maintain smoother performance for longer and require less frequent maintenance, as the black seals prevent water and dirt ingress that would otherwise cause rust and performance degradation in standard bearings.
• Do I need any additional bearings beyond this kit? — For most 2WD VXL trucks (Slash VXL, Bandit VXL, Stampede VXL, Rustler VXL), this complete kit contains every bearing needed. However, if you have a VXL model with the Magnum 272R transmission, you will need to purchase two additional 10x15x4 bearings separately to complete the bearing swap. Similarly, 4WD Extreme HD models require supplementary bearings (5120A and 5117A) not included in this 2WD kit.
• How does this bearing kit improve performance? — By replacing factory bearings with precision stainless steel alternatives that feature quality seals, you reduce friction, improve power transmission efficiency, and maintain consistent handling characteristics even in wet conditions. The sealed design also means your RC truck maintains responsiveness without the performance drop that occurs when standard bearings accumulate moisture and corrosion.
• Is this suitable for UK weather conditions? — Absolutely. This bearing kit is particularly well-suited to UK RC enthusiasts because the stainless steel construction and sealed design provide exceptional protection against the moisture and wet conditions common in British weather. Whether you're bashing in damp parks or racing in drizzle, these bearings will outperform standard factory bearings significantly.
• What is the difference between this and standard factory bearings? — Factory bearings in ready-to-run RC trucks are typically unsealed steel components that corrode and wear quickly when exposed to moisture. This Traxxas kit upgrades you to stainless steel with high-quality black seals, which dramatically improves corrosion resistance, reduces maintenance requirements, and extends the service life of your bearing set substantially.
