Technical Performance
The differential case is a precision-engineered component manufactured to the high standards Team Associated has established as a leading innovator in 1/14 scale RC buggies. The Reflex 14B platform, of which this differential case forms a key component, has been designed with performance in mind, incorporating adjustability through turnbuckles, springs, fluids, shock tower hole placement, and gearing. The inclusion of three sealed differentials on the Reflex 14B buggy—with this case forming the outer housing for one or more of those differentials—represents a significant innovation that increases the potential for grip and corner speed, directly leading to faster lap times and an overall thrilling-to-drive feel. The sealed design protects the internal differential gearing from dirt and moisture whilst maintaining the rotational efficiency required for off-road performance. Combined with the aluminium steering rack and lightweight aluminium centre driveshaft also featured on the Reflex 14B, this differential case contributes to a platform engineered to deliver big performance in a small-scale 1/14 package.

Frequently Asked Questions
- What is the AS21900 differential case used for? — The AS21900 forms the outer housing for a differential assembly on the Team Associated Reflex 14B Classic 1/14 scale buggy. The differential is a critical drivetrain component that allows the rear wheels to rotate at different speeds during cornering, which is essential for maintaining grip, corner speed, and overall handling performance in off-road conditions.
- Is this part compatible with all Reflex 14B models? — This part is specifically designed for the Reflex 14B Classic. We recommend consulting your vehicle manual and cross-checking the AS21900 part number against your vehicle's exploded diagram and spares listing to confirm exact compatibility before ordering, as different configurations may use different components.
- What does natural finish mean? — Natural finish means the part is supplied unpainted, in its base material colour. This allows you to paint it to match your chosen colour scheme, or you can use it as-is for a clean, minimalist aesthetic. Many RC enthusiasts prefer natural finish parts for customisation flexibility.
- Why would I need a replacement differential case? — The differential case may need replacement due to wear from extended use, impact damage from crashes, or if internal gearing has been damaged and requires complete reassembly. Keeping spare differential cases on hand is a smart approach for serious RC buggy racers and enthusiasts.
- How do I know this is the correct part for my buggy? — Check your Reflex 14B Classic vehicle manual for the parts diagram and spares listing. Look for the AS21900 part number to confirm it matches your vehicle. You can also contact our knowledgeable team at RC Model Shop for guidance on part compatibility.
- Is this suitable for beginners? — This is a spare part component rather than a complete product, so it's intended for users who already own a Reflex 14B Classic buggy and have basic RC maintenance knowledge. Beginners should start with a complete ready to run RC buggy kit and learn basic operation before undertaking differential maintenance or replacement.
