Overview
The Traxxas Drive Hub, Center, Rear (1pc) / 4x3 GS (1pc) TRX6888 is an essential spare part for serious RC enthusiasts and competitive bashers across the UK. Whether you're running a Traxxas short course truck, rally car, or off-road buggy, this rear centre drive hub represents genuine OEM quality from one of the world's most respected RC manufacturers. This is not an aftermarket compromise — it's the exact same component fitted to brand new Traxxas vehicles, ensuring perfect compatibility and proven durability on the track and trail.
If you've damaged your existing drive hub through intense racing, accident recovery, or general wear and tear, sourcing the correct replacement is crucial to maintaining your RC car's performance and reliability. The TRX6888 is engineered to the same exacting standards as the original equipment, so you can rebuild your vehicle with complete confidence. This is the kind of part that separates weekend bashers from serious RC competitors — those who understand that genuine spares keep their vehicles running at peak performance.
RC car UK hobbyists know that brushless RC vehicles, especially 4WD and all-terrain models, demand high-quality drivetrain components. This rear centre drive hub is compatible with an extensive range of Traxxas models, from the legendary Slash series to the modern Rustler Ultimate and Mini XRT, making it an indispensable item for any Traxxas owner's spares collection.
Key Features
- Genuine Traxxas OEM Part — This is the authentic factory component, not an imitation or third-party clone, guaranteeing exact fitment and long-term reliability on your ready to run RC car.
- 4x3 mm Grub Screw Included — The drive hub comes complete with the correct grub screw specification (4x3 mm), eliminating the frustration of hunting for matching fasteners and ensuring immediate installation.
- Rear Centre Position — Specifically engineered for rear centre mounting, this hub is precisely calculated for optimal drivetrain geometry and weight distribution in Traxxas suspension designs.
- Compatible with Leading Traxxas Models — Works seamlessly with the Ford Fiesta ST Rally BL-2S, Ford Fiesta ST Rally VXL, Mini XRT VXL-3S, Rustler Ultimate VXL 4x4, Slash Ultimate 4x4 VXL, and Slash VXL series vehicles, offering comprehensive coverage across multiple chassis platforms.
- Proven Durability Under Load — Manufactured to withstand the extreme torque loads generated by modern brushless motors and 3S, 4S, and higher LiPo battery configurations commonly used in competitive RC racing.
Technical Performance
The TRX6888 rear centre drive hub is manufactured from premium quality materials selected to endure the demanding environment of high-performance RC vehicles. The hub interfaces with the differential and axle shafts, transmitting power from the motor through the transmission to the wheels with minimal power loss. Its engineering reflects decades of Traxxas development and real-world track testing, ensuring that every dimension, tolerance, and material specification is optimised for both stock and upgraded drivetrain configurations. The 4x3 mm grub screw provides secure, repeatable fastening without stripping — a critical detail that separates quality OEM components from cheaper alternatives. Whether you're running a stock Slash VXL with a standard 2S or 3S LiPo battery, or pushing a heavily modified Rustler Ultimate with 4S power, this hub handles the mechanical stresses with proven reliability. The rear centre positioning means this component works in concert with your front hubs, suspension geometry, and differential system to deliver the balanced, predictable handling that Traxxas vehicles are famous for amongst the UK RC racing community.

Frequently Asked Questions
- Which Traxxas models use the TRX6888 rear centre drive hub? — This hub is compatible with a wide range of Traxxas vehicles including the Ford Fiesta ST Rally BL-2S, Ford Fiesta ST Rally VXL, Mini XRT VXL-3S in green, orange, red and blue variants, Rustler Ultimate VXL 4x4 in green and blue, Slash Ultimate 4x4 VXL, and multiple colour options of the Slash VXL series short course trucks. If you own any of these models and need drivetrain repairs, this is the correct part.
- Do I need any tools or experience to fit the TRX6888? — Fitting this hub requires basic mechanical knowledge and standard hex key tools. The grub screw is secured with a small hex key (typically 1.5mm), and the hub itself presses or bolts onto the axle shaft depending on your specific chassis design. If you're comfortable working on ready to run RC cars, this is a straightforward replacement job.
- Why would my drive hub need replacement? — Drive hubs can suffer damage through impact accidents, extended high-speed use on rough terrain, or gradual wear in the bore where it mounts to the axle shaft. A damaged or worn hub creates play in the drivetrain, reducing handling precision and potentially allowing the axle to slip under acceleration — both problems solved immediately by fitting this genuine replacement.
- Is this genuine Traxxas or an aftermarket part? — This is 100% genuine Traxxas OEM equipment — the exact same component supplied in new Traxxas vehicles. It carries the official Traxxas part number TRX6888 and EAN code 0020334688804, ensuring authenticity and warranty protection.
- What battery voltage and capacity does my vehicle need? — The drive hub itself is battery-agnostic — it performs the same function whether your vehicle uses 2S, 3S, or 4S LiPo batteries. However, your specific Traxxas model will have manufacturer recommendations, typically ranging from 3S (11.1V) for stock vehicles to 4S (14.8V) or higher for brushless variants.
- Can I upgrade to this hub if my vehicle uses a different model? — No, the TRX6888 is specifically designed for the chassis geometry and differential configuration of the compatible models listed above. Using it on an incompatible platform would result in incorrect drivetrain alignment and handling problems. Always verify compatibility with your specific model before purchasing.
