These aluminium caster C-hub blocks are manufactured to exacting standards and provide a direct replacement or upgrade path for Team Associated RC10 owners and RB10/DR10 builders looking to optimise their suspension geometry and steering response.

Available as a pair, these option parts allow you to adjust your vehicle's caster angle, which is critical for controlling how your RC buggy responds to steering input and how it behaves during cornering. For RC enthusiasts in the UK seeking to upgrade their Associated RB10 or DR10, these aluminium blocks offer a lightweight yet robust solution that will deliver immediate benefits to your driving experience and lap times.

Key Features

• Precision Aluminium Construction — These caster hub blocks are manufactured from high-quality aluminium alloy, providing excellent strength-to-weight ratio that reduces unsprung mass whilst maintaining rigidity and durability under demanding racing conditions.
• Caster Angle Adjustability — The design allows you to modify the caster angle on your Associated RB10 or DR10, which directly influences steering response, cornering stability and how your RC car tracks through turns, giving you granular control over your setup.
• Pair Configuration — Supplied as a matched pair, ensuring consistent performance across both the left and right sides of your vehicle's front suspension and eliminating any imbalance that might affect handling.
• Direct Compatibility — These blocks are engineered as option parts specifically for Team Associated RC10DR Desert Edition and RB10 Retro Kit platforms, guaranteeing perfect fitment and requiring no modification or adaptation.
• Lightweight Performance Enhancement — By using aluminium instead of alternative materials, Fastrax has minimised weight whilst maximising strength, which translates to improved acceleration, braking response and overall vehicle dynamics.
• Professional Race-Grade Components — Designed and approved for competitive RC racing, these parts meet the exacting standards required by serious RC buggy racers and weekend bashers alike who demand reliability and performance consistency.

Technical Performance

The Fastrax FTAS20B caster hub blocks represent an important tuning component in the RC buggy platform ecosystem. Constructed from precision-engineered aluminium, these parts play a crucial role in adjusting your vehicle's caster geometry — the angle of the steering axis relative to vertical. This seemingly small adjustment has profound effects on how your RC car handles: increasing caster improves straight-line stability and self-centring, making the vehicle track more predictably at speed, whilst also improving cornering grip and mid-corner response. The pair design ensures left-right symmetry, which is essential for balanced handling and predictable steering feel. For Team Associated RB10 owners and DR10 Desert Edition builders, these option parts integrate seamlessly with the existing suspension architecture and require no additional modification to the chassis or other components. The lightweight aluminium construction minimises unsprung weight at the front axle, improving suspension responsiveness and reducing the energy required to articulate the suspension, which translates to better traction and control when navigating rough terrain or executing precise track manoeuvres. RC enthusiasts in the UK who are running their Associated buggies on everything from high-grip clay tracks to rough off-road courses will immediately notice the improvement in steering precision and stability once these caster blocks are installed.

Frequently Asked Questions

• What is a caster hub block and why would I need one for my RC buggy? — The caster hub block controls the caster angle of your RC car's steering axis. Adjusting caster affects how your vehicle steers, how stable it feels at high speed, and how responsive it is during cornering. If you're looking to fine-tune your Associated RB10 or DR10 handling characteristics, these blocks allow you to experiment with different caster angles to find the sweet spot for your driving style and track conditions.
• Will these blocks fit my Team Associated RC10DR or RB10? — Yes, these Fastrax blocks are specifically designed as option parts for the Team Associated RC10DR Desert Edition Brushless RTR (model AS90052) and the RB10 Retro Kit (model AS90054). They will fit directly without requiring modification to your chassis or other suspension components.
• Are aluminium caster blocks better than plastic ones? — Aluminium caster hub blocks offer several advantages over plastic alternatives. Aluminium is lighter than plastic while remaining stronger and more rigid, which means better handling precision and durability. The material also dissipates heat more effectively and won't flex or wear as quickly under racing loads, making aluminium blocks a favourite upgrade among competitive RC racers in the UK and globally.
• How do I install these caster blocks on my RC car? — These option parts are designed as direct replacements for the OEM caster hub blocks on your Associated RB10 or DR10. Installation typically involves removing the original blocks and installing these in their place. Refer to your vehicle's instruction manual or the Fastrax specification sheet for detailed step-by-step installation guidance.
• Can I adjust the caster angle once these blocks are installed? — The caster angle is determined by the geometry of these hub blocks themselves. To change caster angle, you would need to source alternative hub blocks with different caster specifications. However, these blocks provide a known, reliable caster angle that suits a wide variety of racing conditions and driving styles.
• Is this suitable for beginners? — These blocks are tuning option parts rather than standalone products. They're best suited to RC enthusiasts who already own an Associated RB10 or DR10 and understand suspension tuning concepts. If you're new to RC tuning, these represent an excellent entry point into suspension geometry adjustments once you're familiar with your vehicle's basic setup and handling characteristics.
• What makes Fastrax a trusted brand for Associated upgrades? — Fastrax specialises in option parts and tuning components for popular RC platforms including Team Associated vehicles. The brand is recognised throughout the UK RC community for delivering high-quality, precision-engineered components at competitive prices, with products that deliver measurable improvements in handling and durability.
