Frequently Asked Questions
- Is the Team Associated B4 Diff Gear 52T suitable for beginners? — This is a replacement spare part rather than a complete vehicle or beginner package. It's ideal for anyone who already owns a Team Associated B4 series RC car and needs to maintain or upgrade their differential components. Beginners should start with a ready-to-run RC car or kit, then utilise spares like this as their vehicle ages or requires maintenance.
- What Team Associated B4 models is this differential gear compatible with? — The AS7664 is designed as a standard fitment part for the Team Associated B4 series vehicles. This includes the B4 and B4.1 models. For compatibility with other Team Associated models like the B4.2, T4.1, T4.2, SC10, SC10GT, SC10B, SC10.2, SC10.3, RC10 Classic, RC10GT, or RC10GB variants, we recommend checking the specific technical documentation or contacting our team for clarification.
- How do I know when to replace my differential gear? — Signs that your differential gear may need replacement include grinding or unusual noises coming from the drivetrain, inconsistent or unpredictable handling during cornering, visible wear or damaged teeth on the gear itself, or a sensation that power isn't being distributed smoothly through the drivetrain. If you've been running your RC car regularly for extended periods, replacing worn differential components as part of preventative maintenance is a sensible approach to keeping your vehicle in peak condition.
- Is this an original Team Associated part? — Yes, the AS7664 is a genuine Team Associated component manufactured to original equipment specifications. This means it meets all the exacting standards that Team Associated sets for their own vehicles, ensuring perfect fitment and performance when installed in a compatible Team Associated B4 series RC car.
- What is the difference between the 2.60:1 and other differential ratios? — Differential gear ratios affect how torque is distributed through your RC car's drivetrain and influence handling characteristics. The 2.60:1 ratio of this component is specifically engineered for Team Associated B4 series vehicles. Different ratios may be available for other models or driving styles, but for B4 series compatibility, this is the standard specification.
- Do I need tools to install this differential gear? — Installation of differential components typically requires basic RC hobby tools and mechanical knowledge. We recommend consulting your Team Associated B4 service manual for detailed installation instructions, or contacting our experienced team at RC Model Shop for guidance if you're uncertain about the installation process.
