- Precision-Cut Design — Manufactured to exact specifications by Team Associated, the precision-cut teeth ensure smooth engagement, minimal backlash and reliable power transmission in all driving conditions.
- Included Differential Gasket — Every light ring gear comes complete with a differential gasket, eliminating the need to source additional sealing components and ensuring a professional-quality rebuild every time you service your differential.
- Family-Wide Compatibility — Compatible across the entire RC8 family including SC8, RC8B, RC8.2, RC8.2e, RC8.2 RS, RC8 and RC8T models, making it a versatile upgrade for multi-car collectors.
- Performance Upgrade for Standard Models — Whilst a direct replacement for RC8.2 vehicles, it functions as an excellent optional upgrade for other RC8 variants, providing measurable improvements to overall vehicle efficiency without requiring complex modifications.
Technical Performance
The Team Associated RC8 Light Diff Ring Gear represents precision engineering at its finest. By reducing rotating mass by approximately 6 grams compared to stock gears, this component directly improves drivetrain responsiveness and efficiency. The reduction in rotating mass means your motor doesn't have to work as hard to accelerate the differential gears, resulting in quicker spool-up and more immediate throttle response during competitive racing or casual bashing sessions. The precision-cut design ensures minimal backlash between the pinion and ring gear teeth, allowing power to be transmitted more effectively from the motor through the differential and out to the wheels. Construction quality is assured through Team Associated's reputation for manufacturing automotive-grade RC components that withstand the rigours of both competitive track use and recreational off-road bashing. The included differential gasket is manufactured to the same exacting standards, ensuring a watertight seal when you rebuild your differential. For RC enthusiasts in the UK seeking to optimise their RC8-family vehicles, this lightweight ring gear is an investment in measurable performance gains that will be felt in every lap or run. Whether you're running your RC car on grass, tarmac or mixed terrain, the improved efficiency delivered by this component translates into better overall handling characteristics and more responsive vehicle behaviour.

Frequently Asked Questions
- Is the Team Associated RC8 Light Diff Ring Gear suitable for beginners? — This component is suitable for anyone with basic differential servicing knowledge. If you're new to RC car maintenance, you may want to consult your RC8 manual or ask an experienced friend for guidance during installation, but the actual fitting process is straightforward. The inclusion of the differential gasket means you have everything needed for a professional rebuild.
- Will this ring gear fit my RC8.2? — Yes, absolutely. The AS89494 is a direct replacement for the Team Associated RC8.2, meaning it will fit perfectly without any modification or additional components required. This is one of the primary reasons it's such a popular upgrade among RC8.2 owners and competitors.
- Can I use this light ring gear in both front and rear differentials? — Yes, this component is designed for use in both the front and rear differentials, giving you flexibility in how you configure your drivetrain. Many users choose to upgrade both differentials for balanced performance improvements across the entire vehicle.
- What performance improvement will I notice? — The 6-gram weight reduction per ring gear translates into improved acceleration response and better overall drivetrain efficiency. You'll notice quicker spool-up of the differential and more responsive throttle input, particularly noticeable during acceleration out of corners on the track. The improvement is subtle but measurable, especially for competitive drivers.
- Is this a direct replacement for all RC8 models? — It's a direct replacement specifically for the RC8.2. For other RC8-family models including the SC8, RC8B, RC8.2e, RC8.2 RS, RC8 and RC8T, it functions as an excellent optional upgrade rather than a direct replacement, offering the same performance benefits with straightforward installation.
- Do I need any additional components to install this ring gear? — The differential gasket is included, so you have everything necessary for a complete differential rebuild. You may want to have some lightweight differential oil on hand for reassembly, but this depends on your specific setup and driving conditions.
- Why is reducing rotating mass important in RC cars? — Rotating mass in the drivetrain requires energy to accelerate and decelerate. By reducing this mass by approximately 6 grams, the motor can spool up the differential more quickly, resulting in faster acceleration and more responsive vehicle behaviour. This is particularly beneficial in competitive racing where every millisecond counts.
