Key Features
- Pro-Built Complete Assembly — This differential arrives fully assembled and pre-filled with high-quality grease, meaning you can install it immediately without requiring complex assembly work or additional setup steps, saving valuable time and reducing the chance of assembly errors.
- Sealed Design — The sealed construction protects internal components from dirt, water and debris whilst containing the grease fill, ensuring consistent performance and extended service life even in challenging RC driving conditions.
- Pre-filled with Grease — The differential comes with factory-applied grease that's been selected for smooth operation and durability, providing consistent limited-slip performance right out of the box for hard-charging RC applications.
- Accepts Silicone Differential Fluid — For drivers who want to fine-tune their drivetrain characteristics, this differential can be drained and refilled with silicone differential fluid to adjust limited-slip performance, offering versatility for different driving styles and track conditions.
- Adjustable Performance Options — By using ultra-thick 500k differential fluid, you can customise the differential's behaviour for specific applications such as drag racing, where maximum traction and controlled wheel spin are critical performance factors.
- Precision Bearings Included — The assembly features 10x15 mm bearings that provide smooth rotation and minimal friction, essential for maintaining top-end speed and efficiency in competitive RC racing situations.
- Pro Series Magnum 272R Transmission Compatibility — Engineered specifically for the Pro Series Magnum 272R transmission, this differential ensures perfect fit, proper gear meshing and optimal performance with zero compatibility concerns.
- Fits Front or Rear Positions — The versatile design allows installation in either the front or rear differential position, making this a flexible upgrade option for vehicles using the compatible transmission.
Technical Performance
This complete differential assembly represents Traxxas's commitment to precision engineering in RC drivetrain components. The sealed construction utilises high-quality materials that withstand the demands of serious RC driving, whether on-road or off-road. The 10x15 mm bearings provide smooth, low-friction rotation that translates directly to improved acceleration and top-speed performance. The factory-applied grease fill is engineered to provide optimal limited-slip characteristics without requiring immediate service, though serious racers and enthusiasts appreciate the option to drain and refill with alternative silicone fluids to customise performance. For drag racing applications specifically, the ability to use ultra-thick 500k differential fluid allows drivers to control wheel spin and maximise traction during high-acceleration launches. The sealed design ensures that regardless of whether you're driving in damp UK conditions or dusty terrain, the internal components remain protected and perform consistently. This is professional-grade equipment that meets the standards expected by competitive RC car and truck drivers who rely on drivetrain reliability as a foundation for winning performance.

Frequently Asked Questions
- Is this differential compatible with all Magnum transmissions? — No. This TRX9480A differential is specifically designed for the Pro Series Magnum 272R transmission only. It does not fit the standard Magnum 272 transmission, so verify your transmission model before purchasing.
- Can I install this differential myself? — Yes. Since the differential comes completely pre-assembled and filled with grease, installation is straightforward for anyone with basic RC maintenance experience. You'll simply need to mount it into your Magnum 272R transmission according to your vehicle's manual.
- Can I change the differential fluid? — Absolutely. Whilst it arrives pre-filled with grease for ready-to-use performance, you can drain this and refill with silicone differential fluid to adjust the limited-slip characteristics. This is particularly useful if you want to fine-tune traction behaviour or optimise for specific driving conditions like drag racing.
- What differential fluid should I use for drag racing? — For drag racing applications where you need maximum traction and controlled wheel spin, Traxxas recommends ultra-thick 500k differential fluid. This heavier fluid provides greater limited-slip effect, helping you launch hard without excessive tyre spin.
- Why would I upgrade to this differential? — If your current differential is damaged, worn or you're rebuilding your drivetrain, this genuine Traxxas replacement ensures perfect compatibility with your Pro Series Magnum 272R transmission. Even if your existing differential is functional, upgrading to a fresh assembly can improve performance consistency and reliability.
- Does this differential work in both front and rear positions? — Yes. This is a versatile assembly that can be installed in either the front or rear differential position, giving you flexibility depending on your specific vehicle configuration and upgrade requirements.
- What makes this better than a used differential? — As a brand-new complete assembly, this differential comes with factory-fresh components, proper bearing preload, and consistent grease fill. You're guaranteed optimal performance without the uncertainty of worn internal parts or contaminated fluid that can compromise reliability.
