Overview
The Associated RC8B4e FWB/RWB Adapter + 96.5mm Dogbone Set (AS81645) is an essential upgrade kit for RC enthusiasts looking to modernise their RC8B4e chassis to the latest weight bias system. This adapter set enables your existing RC8B4e to be updated to the new FWB/RWB (Front Weight Bias/Rear Weight Bias) chassis configuration, which represents a significant evolution in chassis dynamics and performance tuning capability. Whether you're a competitive racer pushing for lap time improvements or a dedicated hobbyist seeking to maximise your RC car UK investment, this upgrade kit provides the mechanical foundation needed to unlock the full potential of the RC8B4e platform.
Associated is recognised globally as a leader in precision RC engineering, and this adapter set exemplifies their commitment to backward compatibility and user upgradability. Rather than forcing customers to purchase an entirely new chassis, Associated has engineered this comprehensive adapter solution that allows existing RC8B4e owners to transition seamlessly to the new FWB/RWB system. The kit includes everything required for the conversion except the main FWB/RWB chassis itself, making it an economical way to breathe new life into your existing investment whilst maintaining the proven reliability that Associated is known for throughout the RC community.
This is particularly valuable for UK RC car enthusiasts who demand precision engineering and the ability to fine-tune their setups to suit different track conditions and driving styles. The inclusion of the 96.5mm centre dogbone set demonstrates Associated's attention to detail, as dogbone length directly affects the handling characteristics and weight distribution of your RC buggy. For those serious about competitive racing or simply wanting the best performance from their RC car, this adapter kit represents a straightforward path to staying current with the latest chassis technology.
Key Features
- FWB/RWB Chassis Compatibility — This adapter set enables your RC8B4e to be updated to the new weight bias chassis system, which allows you to adjust the chassis balance between front weight bias and rear weight bias configurations, giving you unprecedented tuning flexibility for different track layouts and driving conditions.
- 96.5mm Centre Dogbone Set Included — The kit includes the complete 96.5mm centre dogbone set, which is a critical component for the FWB/RWB conversion and directly impacts the suspension geometry and handling characteristics of your RC buggy.
- Complete Conversion Solution — Combined with the AS81644 FWB/RWB chassis, this adapter set provides everything needed to fully update your RC8B4e to the new system, with comprehensive update instructions included to guide you through the conversion process.

Technical Performance
The Associated RC8B4e FWB/RWB Adapter + 96.5mm Dogbone Set represents a precision engineering solution designed to modernise the RC8B4e platform without requiring complete chassis replacement. The 96.5mm centre dogbone specification is critical to the performance envelope of this system, as dogbone length directly influences suspension geometry, weight distribution, and the vehicle's handling balance across different track surfaces. This shorter dogbone length compared to the original 104mm component allows for fine-tuning of the chassis weight bias characteristics, enabling drivers to shift the balance toward either front or rear depending on track conditions and personal driving preferences. The adapter components are manufactured to Associated's exacting tolerances, ensuring perfect fitment with the AS81644 FWB/RWB chassis and maintaining the precision engineering that competitive RC racing demands. The complete system maintains compatibility with existing RC8B4e drivetrains and suspension components, meaning your investment in proven motor systems, ESCs, and battery solutions continues to deliver maximum value. The engineering philosophy behind this conversion kit reflects the current generation of RC buggy design thinking, where adjustable weight bias and modular chassis configurations provide the competitive edge needed in modern racing, whether you're competing at the highest levels of UK RC racing or simply seeking to extract maximum performance from your RC car setup.

Frequently Asked Questions
- What do I need to upgrade my RC8B4e to the FWB/RWB chassis system? — You will need both the AS81644 FWB/RWB chassis and this AS81645 adapter kit to complete the upgrade. The instructions provided in both kits will guide you through the conversion process. You can reuse the original AS81581 104mm centre dogbone from your existing RC8B4e kit with the new system.
- What is the difference between the 96.5mm and 104mm centre dogbones? — The centre dogbone length affects the suspension geometry and the overall handling balance of your RC buggy. The shorter 96.5mm dogbone is designed for the FWB/RWB chassis system, whilst the original 104mm dogbone is retained as part of the new configuration. The change in length influences weight distribution and allows for the FWB/RWB tuning capabilities.
- Can I use this adapter set with my existing RC8B4e components? — Yes, this adapter kit is specifically designed to work with your existing RC8B4e drivetrain, motor system, batteries, and transmitter. The conversion maintains compatibility with all your current components, making it an economical upgrade solution.
- Do I need to replace my entire RC8B4e when upgrading to FWB/RWB? — No, that's the key benefit of this adapter system. Rather than purchasing a completely new RC buggy, you can upgrade your existing RC8B4e with the AS81644 chassis and this AS81645 adapter set, preserving your investment in existing components.
- Are spare dogbones available separately? — Yes, the 96.5mm centre dogbone set is available separately as AS81646, making it easy to maintain your RC buggy or build additional setups with different configurations.
- Is this suitable for competitive racing? — Yes, this adapter kit is designed for the RC8B4e platform used in competitive racing environments. The precision engineering and FWB/RWB tuning capability provide serious racers with the setup flexibility needed to optimise performance for different track conditions.
- What instructions are provided with the adapter kit? — Comprehensive update instructions are included in the package. These guides walk you through the conversion process step-by-step, ensuring successful installation regardless of your experience level with RC car assembly and maintenance.
