Whether you're ordering online for home delivery or visiting an RC hobby shop, the TRX9480 is the authentic Traxxas part that serious Drag Slash owners trust.

Key Features

• Absorbs Driveline Shocks — The centre differential is engineered to absorb the intense shocks that occur during acceleration and shifting, protecting your entire drivetrain from damage and extending the service life of your RC car's components.
• Distributes Power Evenly — By distributing power evenly across the drive system, this differential enables maximum acceleration performance, helping your Drag Slash achieve consistent, predictable launches off the line.
• Factory-Installed 47-Tooth Spur Gear — Comes equipped with a precision 47-tooth, 32-pitch spur gear that has been factory-assembled and tested, ensuring optimal gear mesh and performance characteristics right out of the box.
• Sealed Design — The sealed differential construction prevents contamination from dirt, dust and moisture, maintaining performance even in outdoor RC racing environments typical across the UK.
• Pre-Loaded with 500K Silicone Oil — The differential arrives pre-filled with premium 500K viscosity silicone oil, which helps prevent unloading and ballooning of the front tyres during aggressive acceleration, a critical advantage in drag racing.
• Prevents Tyre Ballooning — The silicone oil loading specifically combats the tyre ballooning effect that can occur under extreme acceleration forces, maintaining consistent contact patch and traction.
• Completely Assembled — This is a ready-to-install assembly requiring no additional building or tuning, making it ideal for both experienced racers and those new to RC car maintenance.
• Genuine Traxxas OEM Part — As an official Traxxas spare part, you can be confident this is the exact component your Drag Slash was engineered to use, ensuring perfect fitment and compatibility.

Technical Performance

The Traxxas TRX9480 differential assembly represents the pinnacle of drivetrain engineering for drag racing RC cars. Built with precision machining and quality materials throughout, this centre differential has been engineered to withstand the extreme forces generated during competitive drag racing. The inclusion of the factory-installed 47-tooth, 32-pitch spur gear demonstrates Traxxas' attention to detail — this specific gear configuration has been selected to provide optimal performance characteristics for the Drag Slash platform. The sealed differential construction utilises high-quality bearing surfaces and tight tolerances to minimise play and maximise responsiveness. The pre-loaded 500K silicone oil serves multiple critical functions: it acts as a load-limiting mechanism to prevent the differential from unloading under extreme acceleration, it provides lubrication to the internal gears and bearings for smooth operation, and it helps maintain tyre contact by reducing the ballooning effect that occurs when front tyres expand under lateral and longitudinal acceleration forces. For serious drag racers in the UK looking to upgrade their RC car's drivetrain reliability and performance, this component delivers measurable improvements in consistency, durability and off-the-line acceleration characteristics. The engineering quality and factory assembly mean you're not compromising on any aspect of performance — this is a professional-grade component designed for competitive use.

Frequently Asked Questions

• Is the Traxxas TRX9480 differential suitable for beginners? — Yes, this is an excellent component for any Drag Slash owner, regardless of experience level. Because it comes completely assembled and pre-filled with oil, there's no complex building or tuning required — simply install it into your RC car and you're ready to race.
• What does the 500K silicone oil do in the differential? — The 500K viscosity silicone oil serves as a load-limiting fluid that prevents the differential from unloading under extreme acceleration forces. This is critical in drag racing because it helps prevent tyre ballooning (where the tyres expand and lose contact patch) and maintains more consistent traction off the line. The oil also provides continuous lubrication to the internal gears and bearings.
• What is the 47-tooth, 32-pitch spur gear for? — The spur gear is the main drivetrain component that transfers power from the motor to the rest of the drive system. The 47-tooth, 32-pitch configuration has been specifically chosen by Traxxas engineers to provide optimal performance for the Drag Slash platform, offering the right balance of acceleration and top-end performance.
• Will this differential work with my Drag Slash? — Yes, the TRX9480 is the complete differential assembly specifically designed for Traxxas Drag Slash RC cars. It fits directly into your Drag Slash chassis without modification and is compatible with all Drag Slash variants.
• Do I need to add oil or perform any setup before installation? — No, this assembly comes completely ready to use. The 500K silicone oil is already pre-loaded at the factory, so you simply install the differential into your Drag Slash and begin racing. This is a significant convenience advantage over individual differential components.
• Is this a sealed differential? — Yes, the differential features sealed construction, which means the internal gears and bearings are protected from external contaminants like dirt, dust and moisture. This is particularly important for outdoor RC racing in the UK where weather conditions can be variable.
• What makes this different from other differential options? — The TRX9480 is the genuine Traxxas OEM (original equipment manufacturer) differential assembly for the Drag Slash. It comes completely assembled and pre-loaded with the correct silicone oil, whereas aftermarket or universal differentials may require additional tuning, oil selection and assembly. As the factory-engineered solution, it offers superior compatibility and performance optimisation specifically for your Drag Slash.
• How often will I need to maintain or replace the differential? — With proper care and normal use, the sealed differential design minimises maintenance requirements. However, if you experience a crash or damage, or if you notice any unusual noises or performance changes, you may need to have the differential inspected by an RC hobby specialist or serviced by Traxxas.
