TRX7014

Overview

The Traxxas Differential Kit, Centre (Complete) TRX7014 is an essential performance upgrade for owners of the Traxxas 1/16 Slash and 1/16 E-Revo VXL 4x4 models. This optional centre differential is specifically engineered to optimise power distribution across your RC car's drivetrain, delivering noticeable improvements in handling, stability and steering response. Whether you're a weekend basher enjoying your RC short course truck or a serious enthusiast looking to fine-tune your brushless RC model, this differential kit addresses one of the most common performance issues faced by 1/16 scale 4WD RC vehicle owners: front-end lift during acceleration.

The centre differential works by balancing how power is distributed between the front and rear axles, which significantly reduces the tendency of your RC car to wheelie or lose traction when accelerating hard. Users consistently report that this upgrade eliminates understeer issues, improves overall steering responsiveness, and allows for tighter, more controlled turns at high speeds. For anyone running a Traxxas VXL brushless 4x4 in the UK, this is a recognised must-have upgrade that transforms the driving experience and gives you far greater control over your vehicle's behaviour on various surfaces and track conditions.

What sets this Traxxas differential apart is its fully tunable design. Rather than being a fixed component, the differential's behaviour can be customised by changing the silicone fluid viscosity, allowing you to dial in the exact performance characteristics that suit your driving style and local track conditions. The kit arrives factory-filled with pure silicone oil, ready to use straight out of the box, though alternative viscosities are available separately if you want to experiment and find your perfect setup.

Key Features

• Centre Differential Design — This is a true centre differential, not a simple upgrade part, which means it sits between the front and rear differentials and actively manages power distribution across all four wheels, giving you superior control compared to vehicles without centre differential action.
• Balances Power Distribution — By carefully regulating how much power goes to the front and rear axles, this differential eliminates the common problem of front-end lift during hard acceleration, keeping your RC car planted and stable even under aggressive driving conditions.
• Reduces Front-End Lift — The most noticeable benefit users report is the elimination of wheelies and front-end lift, which means you maintain better traction and can accelerate harder without losing control or damaging your suspension components.
• Improves Steering Responsiveness — With balanced power distribution, your RC car responds more precisely to steering inputs, making it easier to navigate tight corners and execute precise manoeuvres with confidence.
• Fully Tunable Performance — Unlike fixed differentials, this kit's behaviour is completely customisable by changing the silicone fluid viscosity, allowing you to adjust the differential lock-up characteristics to match your driving style, track surface and weather conditions.
• Factory-Filled with Pure Silicone Oil — The differential comes pre-filled with premium pure silicone oil, meaning it's ready to install and use immediately without any additional setup or mixing required.
• Solves Common Handling Issues — Real users have confirmed this upgrade eliminates understeer problems, reduces tyre ballooning, calms down wheelies, and significantly improves overall steering precision and turning radius.
• Designed for 1/16 Scale Traxxas Models — This is a genuine Traxxas component engineered specifically for the 1/16 Slash and 1/16 E-Revo VXL 4x4, ensuring perfect compatibility and fitment with no modifications required.

Technical Performance

The Traxxas TRX7014 centre differential represents proper engineering for 1/16 scale brushless RC vehicles. This is a complete differential assembly, not a partial upgrade, which means all internal components are included and pre-assembled. The differential's internal design uses premium materials and precision manufacturing to ensure smooth operation and long service life even under the extreme loads generated by brushless VXL motors in 4WD vehicles. The use of pure silicone oil as the factory fill is particularly important because silicone oil maintains consistent viscosity across a wide temperature range, meaning your differential will perform reliably whether you're running your RC car in summer heat or cooler autumn conditions typical of UK climate. The tuneability of this differential is a significant advantage over cheaper alternatives — by selecting different silicone fluid viscosities (sold separately), you can adjust the amount of differential lock-up from more open to more locked, allowing you to optimise for specific driving conditions. Lighter viscosity fluids allow the differential to be more open, providing better turning and steering response but with less front-end stability during acceleration. Heavier viscosity fluids create more lock-up, improving stability and traction but potentially reducing turning response. This adjustability means you're not locked into one performance profile — you can experiment and dial in the perfect balance for your particular vehicle, driving style and local track layout.

Frequently Asked Questions

• Will this centre differential work with my 1/16 Traxxas RC car? — Yes, this kit is compatible with the Traxxas 1/16 Slash 4WD and the Traxxas 1/16 E-Revo VXL 4x4. If you own either of these brushless RC vehicles, this differential is designed to fit perfectly without any modifications.
• What problems does a centre differential actually solve? — The main issues this upgrade addresses are front-end lift and wheelies during acceleration, understeer in corners, excessive tyre ballooning, and poor steering response. Users report that after installing this differential, their vehicles handle much more precisely and remain more stable under hard acceleration, making them more fun and easier to control.
• Can I adjust how this differential performs? — Yes, absolutely. This is one of the key advantages of this differential kit. By changing the silicone fluid viscosity, you can adjust the differential lock characteristics to suit your preferences. Lighter fluids provide more open differential action for better turning, whilst heavier fluids provide more lock-up for stability. Alternative viscosities are sold separately if you want to experiment.
• Is this suitable for beginners? — Whilst this is an optional upgrade rather than a beginner-required part, even newer RC enthusiasts will benefit from improved handling and stability. The installation process requires basic mechanical knowledge and tools, and the component is designed to work with standard Traxxas vehicles, so there's nothing particularly complicated about fitting it. Experienced support staff at RC Model Shop can provide guidance if needed.
• What is the difference between this centre differential and just using the standard differential? — The standard vehicles come with front and rear differentials but no centre differential. Adding a centre differential gives you a third differential unit that manages power distribution between front and rear axles, creating a fully independent four-wheel system with better overall balance and control. This results in noticeably better handling characteristics that users consistently praise.
• Does this come with silicone oil? — Yes, the kit is factory-filled with pure silicone oil, so you can install it and use it immediately. If you want to experiment with different performance characteristics, alternative viscosity fluids are available separately.
• Will this help me turn tighter corners? — Yes, multiple users have reported that this differential improves turning response and allows for tighter, more controlled cornering. The improved steering responsiveness combined with better weight distribution means your RC car responds more precisely to your steering inputs.
