TRX5414

Overview

The Traxxas Centre Differential Kit (TRX5414) is a premium upgrade component designed specifically for Traxxas Revo models, offering serious RC enthusiasts and competitive racers the ability to fine-tune their vehicle's handling characteristics and power distribution. This complete differential assembly arrives pre-assembled with 100K oil, meaning you can get straight to installation without requiring additional preparation or expertise. Whether you're running a Revo 3.3 nitro-powered RC monster truck or upgrading a Revo 2.5R, this differential kit represents a significant performance enhancement that addresses one of the most common handling challenges in high-powered RC vehicles — front-end lift during aggressive acceleration.

If you're serious about optimising your Revo's performance on the track or at the bash spot, the centre differential is a recognised upgrade path for UK RC enthusiasts looking to gain competitive advantage. This is the kind of upgrade that separates weekend bashers from dedicated racers who want to extract maximum performance from their nitro-powered RC truck. The centre differential helps balance the distribution of power across the drivetrain, reducing unwanted weight transfer and improving overall steering responsiveness when you need it most.

At RC Model Shop, we stock genuine Traxxas components and upgrades like this TRX5414, understanding that serious RC hobbyists need access to quality OEM parts that maintain the integrity and performance of their vehicles. This differential kit is the real deal — authentic Traxxas engineering that's been tested and trusted by RC competitors across the UK.

Key Features

• Pre-assembled with 100K oil — This differential arrives fully assembled and already filled with Traxxas 100K synthetic differential oil, eliminating the need for complex assembly or initial fill procedures. You simply need to install it into your Revo chassis and you're ready to test the performance gains immediately.
• Designed for Revo 3.3 and Revo 2.5R compatibility — The kit is engineered as a complete solution for Traxxas Revo models, with support for both the modern Revo 3.3 and the earlier Revo 2.5R platform (note that Revo 2.5R users will require the optional short-rear output shaft, part number TRX5416, sold separately).
• Forward-only conversion included — The kit includes everything needed for forward-only conversion setup, which is essential for optimising the differential's performance characteristics in racing or high-performance driving scenarios.
• Reduces front-end lift during acceleration — By helping to balance power distribution to the front and rear axles, the centre differential significantly reduces the tendency of your Revo to lift its nose during hard acceleration, keeping the vehicle planted and improving traction.
• Improves steering responsiveness — With better weight distribution and more predictable power delivery, your Revo will respond more naturally to steering inputs, giving you sharper cornering and more confidence in competitive situations or technical terrain.
• Complete assembly for Revo — This is a comprehensive centre differential kit, not a partial upgrade, meaning it includes all internal components needed for proper operation and longevity.

Technical Performance

The centre differential is a sophisticated component in the Traxxas Revo's transmission system that works by distributing engine power more evenly between the front and rear differentials. Rather than all available power going to the axle with the least resistance (which typically causes the front end to lift dramatically on acceleration in powerful nitro RC trucks), the centre differential uses a limited-slip design to balance this power delivery. The 100K synthetic oil specified in this kit is specifically formulated to provide the right amount of friction and slip characteristics for performance driving at high speeds. The pre-assembly ensures that internal clutches, gears, and friction plates are properly aligned and seated, which is critical for achieving consistent differential lock-up behaviour. For Revo 3.3 users, this is a direct fit upgrade that requires no modification to the chassis. The Revo 2.5R installation is equally straightforward once you source the compatible short-rear output shaft (TRX5416). The engineering behind this differential represents decades of Traxxas racing experience, with the component having been validated through countless hours of on-track testing by professional RC competitors. The forward-only conversion setting prevents the differential from allowing full lock-up in reverse, which helps prevent drivetrain damage when reversing at high speeds or on slippery surfaces.

What's in the Box

• Centre differential assembly (pre-assembled)
• 100K synthetic differential oil (pre-filled)
• Forward-only conversion components and instructions

What You Need to Complete

• Traxxas Revo 3.3 or Revo 2.5R chassis (if you don't already own one)
• Short-rear output shaft TRX5416 (required only for Revo 2.5R standard chassis)
• Basic RC maintenance tools (hex drivers, screwdrivers)
• Differential oil if you plan to adjust lock-up characteristics later (sold separately)

Frequently Asked Questions

• Which Traxxas Revo models is this centre differential kit compatible with? — The TRX5414 is designed as a complete centre differential solution for both the Revo 3.3 and Revo 2.5R chassis. For the Revo 2.5R, you'll also need to purchase the short-rear output shaft (TRX5416) separately, as the standard Revo 2.5R uses a different rear output configuration. The Revo 3.3 will accept this kit without any additional parts.
• What exactly does a centre differential do and why would I want to upgrade to one? — A centre differential distributes engine power more evenly between the front and rear axles instead of allowing all power to favour whichever axle has less traction. On a powerful nitro Revo, this means less dramatic front-end lift during acceleration, more predictable handling, sharper steering response, and ultimately faster lap times or more controlled bashing. It's a crucial upgrade for serious racers and competitive enthusiasts.
• Is the centre differential difficult to install on my Revo? — Installation is straightforward for most RC enthusiasts with basic mechanical experience. The differential comes pre-assembled with oil already installed, so you're simply removing the old differential (if upgrading from a standard setup) and installing this new unit. You'll need basic RC tools like hex drivers and screwdrivers. If you're uncertain about installation, RC Model Shop staff can provide guidance.
• What oil does this differential use and can I adjust the lock-up characteristics? — This kit arrives filled with Traxxas 100K synthetic differential oil, which provides the factory-tested performance balance. Yes, you can adjust lock-up characteristics by using thicker or thinner oils (Traxxas offers other viscosity ratings), but the 100K oil is the starting point that most users find delivers the best combination of performance and reliability.
• Do I need any special tools to install this differential kit? — Basic RC hand tools are sufficient: hex drivers (typically 1.5mm and 2mm), Phillips and flat-head screwdrivers, and ideally a feeler gauge for proper assembly gaps. You do not need any specialist equipment, though having a clean workspace and a small drain pan for any residual oil is helpful.
• What is the forward-only conversion and why is it included? — The forward-only conversion modifies how the differential behaves in reverse gear, preventing full lock-up and reducing the risk of drivetrain damage when backing up at speed or on slippery surfaces. This is included in the kit and should be installed as part of your setup for maximum reliability.
• Is this a complete centre differential solution or will I need additional parts? — For Revo 3.3 owners, this is completely self-contained. For Revo 2.5R users, you'll need the TRX5416 short-rear output shaft, which is sold separately. Beyond that, you have everything needed for a fully functional centre differential upgrade.
