Key Features

• Front and Rear Cable-Actuated Locking System — This kit provides functional locking differentials for both the front and rear axles of your TRX-4, allowing you to engage maximum traction when needed and disengage for tighter turning when exploring tighter terrain or navigating technical obstacles that require precision steering.
• Complete Assembly Included — The differentials arrive fully assembled and ready to install, saving you valuable build time and ensuring professional quality construction straight from the box, which is particularly valuable for RC enthusiasts who want to upgrade their crawler without spending hours on technical assembly work.
• T-Lock Cable System — The innovative T-Lock cables provide smooth, reliable engagement and disengagement of the locking mechanism, giving you precise control over your differential behaviour and enabling you to adapt your setup instantly to changing terrain conditions during your crawling sessions.
• Integrated Servo Control — The included servo integrates seamlessly with your transmitter to operate the locking mechanism, providing wireless control that lets you switch between locked and unlocked differentials on the fly without stopping your crawler or manual adjustment.
• Enhanced Traction on Difficult Surfaces — Lock both differentials simultaneously to dramatically increase traction when climbing steep inclines, traversing rocky terrain, or negotiating obstacles where wheel slip would otherwise limit your progress and compromise control.
• Improved Turning Radius — Leave the differentials unlocked for a tighter turning radius when navigating technical courses or exploring confined spaces, giving you the manoeuvrability needed for precision driving and complex trail courses.
• Maximum Flexibility — The flexibility to switch between locked and unlocked modes means you can tackle any terrain challenge your local RC sites offer, making this upgrade suitable for the widest range of driving conditions and scenarios.
• Traxxas Quality Engineering — Built to the rigorous standards that Traxxas is renowned for, this differential kit delivers reliability and performance that will withstand the demands of serious RC crawling and extensive use.

Technical Performance

The Traxxas TRX8195 locking differential upgrade represents a significant engineering achievement in RC crawler technology. This transmission tune-up option is engineered specifically for the TRX-4 Sport platform, a 1/10 scale 4x4 electric all-terrain crawler that has become a cornerstone model for UK RC enthusiasts exploring the crawler and off-road scene. The assembled differentials utilise cable actuation technology to provide reliable, responsive control over the locking mechanism, eliminating the need for complex electronic switching whilst maintaining ease of operation through your radio system. The included servo provides the mechanical actuation needed to smoothly engage and disengage the locks, with the T-Lock cables transmitting this motion to both front and rear axles with precision. The engineering focuses on durability and reliability, ensuring that the system performs consistently even after repeated engagement cycles and use in challenging, muddy, or wet conditions typical of UK trail centres and off-road locations. The complete assembly approach means all components arrive optimised and tested, eliminating potential compatibility issues and ensuring that the system works seamlessly within your TRX-4 Sport's transmission architecture from the moment installation is complete.

What's in the Box

• Front locking differential (fully assembled)
• Rear locking differential (fully assembled)
• T-Lock cables (complete set for front and rear actuation)
• Servo (integrated for differential control)
• All necessary hardware for installation

What You Need to Complete

• 4-channel transmitter (sold separately) — essential for correct operation of the locking differential system, as you will need at least one dedicated channel to control the locking mechanism independently of steering and throttle functions
• Traxxas TRX-4 Sport compatible vehicle (see compatibility list below)

Frequently Asked Questions

• Which TRX-4 Sport models is this locking differential kit compatible with? — The TRX8195 is designed for all TRX-4 Sport variants, including the standard TRX4 Sport 1/10 4x4 electric all-terrain crawler truck with clipless body in blue or grey, the TRX-4 Sport Hightrail Edition in metallic blue, and the TRX-4 Sport with deep-terrain Traxx tracks and clipless body in either orange or blue. If you own any version of the TRX-4 Sport platform, this upgrade will be compatible with your vehicle.
• What is the difference between locked and unlocked differential mode? — When the differentials are unlocked, they function as open differentials, allowing the front and rear wheels to rotate at different speeds, which gives you a tighter turning radius and more nimble handling when navigating tight corners or technical obstacle courses. When locked, both the left and right wheels on that axle rotate at the same speed, maximising traction and power delivery to the terrain, which is essential when climbing steep inclines, traversing rocky or muddy surfaces, or tackling other challenging terrain where wheel slip would limit your progress.
• Do I need a special transmitter to use this kit? — Yes, you will need a 4-channel transmitter at minimum to operate the locking differential system correctly. The transmitter must have at least four independent channels so that you can control steering, throttle, and the locking mechanism separately. Most modern RC transmitters sold in the UK meet this requirement, but if you are using an older or budget radio system with fewer channels, you may need to upgrade to take full advantage of this kit.
• Is this suitable for beginners? — Whilst the differentials themselves arrive fully assembled and ready to install, this is an intermediate to advanced upgrade rather than a beginner product. You will need mechanical aptitude to install the kit correctly, and you need to understand how differential locking affects vehicle dynamics to use it effectively. However, experienced RC enthusiasts and anyone with basic mechanical skills should find the installation and operation straightforward, and the improved performance and control it offers makes it a worthwhile upgrade for anyone serious about exploring challenging terrain with their TRX-4 Sport.
• What terrain benefits most from locking differentials? — Locking differentials are particularly valuable on rocky terrain, steep inclines, muddy or loose surfaces, and any challenging off-road landscape where maintaining traction is critical to making progress. UK trail centres, moorland, forestry tracks, and technical obstacle courses all benefit significantly from the added traction that locking differentials provide, making this upgrade an excellent investment if you regularly explore diverse terrain types.
• Will this upgrade affect my turning radius negatively? — No, because you have full control over when the differentials are locked or unlocked. When you need to navigate tight corners or technical courses, you simply unlock the differentials, and your turning radius remains as responsive as before. This flexibility is one of the key advantages of the T-Lock system over permanently locked differentials, giving you the best of both worlds depending on the terrain you are exploring at any given moment.
• How reliable is the cable actuation system? — The T-Lock cable system is engineered to Traxxas' high standards and is designed for reliable, repeatable operation across thousands of engagement cycles. The cables are protected by the differential housings and are not exposed to direct impact, and the cable-driven design is simpler and more robust than electronic alternatives, making it an excellent choice for off-road use where reliability is paramount.
