Technical Performance
The Associated Reflex 14B/14T Differential Case Set represents the pinnacle of small-scale RC drivetrain engineering, designed for 1/14 scale models that demand precision and reliability in equal measure. The differential case assembly is manufactured from durable metal materials, providing exceptional strength and wear resistance across extended use. The set includes precision-engineered planetary gears and sun gears that work in harmony to distribute power smoothly to both wheels whilst allowing the inside wheel to rotate slower than the outside wheel during cornering—a critical function for maintaining control and reducing tyre scrubbing during turns. The cross pin mechanism ensures the gears remain properly aligned within the case, maintaining the correct mesh geometry essential for smooth, quiet operation and efficient power transmission. The differential cap seals the assembly, keeping lubricant in and contaminants out, which is particularly important for RC cars that may be driven in dusty or damp conditions. The engineering principles behind this differential are identical to those used in full-size vehicles, scaled precisely for 1/14 scale performance. Whether you're pushing your Reflex to competitive limits or enjoying relaxed weekend bashing, this differential case set maintains the geometry and responsiveness your model requires. The metal construction resists the wear and tear that plastic alternatives succumb to, extending the serviceable life of your drivetrain significantly. Regular differential maintenance—which this replacement kit facilitates—is one of the most cost-effective ways to preserve the overall health of your RC car UK investment.

Frequently Asked Questions
- Is the Associated Reflex 14B/14T Differential Case Set suitable for beginners? — Yes, this differential case set is suitable for any RC enthusiast, though installation does require basic mechanical aptitude and access to your vehicle's transmission. If you're new to RC maintenance, we recommend consulting your Reflex manual or watching instructional videos before starting the replacement. The modular design makes the job straightforward for anyone comfortable removing and reassembling drivetrain components.
- Do these gears have hardened steel construction? — The differential components are manufactured from durable metal materials designed for RC applications. Whilst we cannot independently verify whether they are specifically hardened steel, they are engineered to withstand the demands of 1/14 scale RC driving and provide excellent durability and wear resistance compared to plastic alternatives.
- How often should I replace my differential case set? — Under normal recreational use, a well-maintained differential can last for many months or longer. However, if you notice increased noise from the drivetrain, grinding sounds, or loss of power delivery, it's time to replace the differential case set. Racing teams or drivers running aggressively may need to replace differential components more frequently due to higher stress levels.
- Will this fit my Reflex buggy or truggy? — This differential case set is compatible with the Reflex 14B, Reflex 14T, Reflex 14R, Reflex 14R Hoonitruck, Reflex 14MT Monster Truck, Reflex 14B Ongaro, and Reflex 14B Buggy. Check your specific model designation to confirm compatibility, though this kit covers the vast majority of Reflex 1/14 scale models in the current lineup.
- Is this an original Associated part or a clone? — This is a genuine OEM (Original Equipment Manufacturer) differential case set from Team Associated, not an aftermarket clone or third-party reproduction. Using genuine parts ensures perfect fitment, proper performance characteristics, and reliable operation that matches your vehicle's factory specifications.
- What tools do I need to install this differential case set? — You'll need basic RC maintenance tools including small metric hex wrenches or Allen keys, a small screwdriver, and possibly a differential puller or small hammer to remove the old case assembly. A service manual specific to your Reflex model provides step-by-step guidance for the removal and installation process.
- Can I use this differential case set with aftermarket gears or electronics? — Yes, this genuine Associated case set is compatible with original Associated differential components and is designed to work reliably with your Reflex's stock motor and drivetrain configuration. If you've upgraded other drivetrain components, ensure they are compatible with 1/14 scale Reflex specifications before installation.
