Team Associated Buggy Caster Block Hat Bushings 0.5mm 1.5mm 2.5mm AS91681

Overview

The Team Associated AS91681 Buggy Castor Block Hat Bushings represent essential precision components for serious RC buggy enthusiasts and competitors throughout the UK. These 0.5mm, 1.5mm and 2.5mm caster block bushings are engineered to deliver the exact suspension geometry adjustments needed to fine-tune your RC car's handling characteristics and performance on the track. Whether you're building a competition-grade RC buggy or maintaining an existing chassis, these genuine Team Associated parts provide the precision fit and durability required for consistent, race-proven results. As part of Team Associated's comprehensive range of buggy spare parts and upgrades, these bushings are recognised as essential tuning components for racers who demand the highest level of control over their vehicle's setup.

Caster block bushings play a critical role in RC buggy suspension tuning, allowing drivers to adjust the angle of the front wheels in relation to the vertical plane. By selecting different bushing thicknesses, you can modify your buggy's caster angle to suit specific track conditions, driving styles and racing requirements. The AS91681 kit provides a complete selection of three different sizes, enabling you to experiment and dial in the perfect setup for maximum cornering performance, stability and responsiveness. This versatility makes these bushings invaluable for any serious RC buggy racer looking to optimise their vehicle's on-track handling without requiring complete suspension rebuilds.

For RC enthusiasts building or upgrading a Team Associated buggy—whether it's a B6 model, B74 platform, or any compatible chassis from the extensive Team Associated range—these caster block hat bushings are a stock-standard part that ensures compatibility with the precision engineering of your buggy's front-end geometry. Quality suspension tuning is what separates competitive racers from casual drivers, and these bushings give you the precise control needed to achieve that edge on the track.

Technical Performance

Caster angle adjustment is one of the most important suspension tuning parameters in RC buggy racing. The caster block hat bushings control the inclination of the front steering knuckles and work directly with your buggy's front caster blocks and suspension arms. By selecting different bushing thicknesses from the 0.5mm, 1.5mm and 2.5mm options included in the AS91681 kit, you alter the effective caster angle of your front end. A smaller caster angle (achieved with thinner bushings like the 0.5mm option) typically results in quicker steering response and easier turn-in, making it suitable for tight, technical tracks. A larger caster angle (achieved with thicker bushings like the 2.5mm option) provides greater straight-line stability, increased high-speed cornering grip and more resistance to steering inputs, making it ideal for faster, more open tracks. The 1.5mm option offers a balanced middle ground suitable for general-purpose racing and practice sessions. These genuine Team Associated components are manufactured to the same precision tolerances as the original parts fitted to factory Team Associated RC buggies, ensuring perfect fitment and eliminating any play or slop in your suspension geometry. The bushings are designed to work seamlessly with the RC10B6 caster block system found across multiple Team Associated chassis platforms, making them an essential spare part for any serious RC buggy racer in the UK or beyond who wants to maintain their vehicle or experiment with different suspension setups.

Always verify your specific chassis model against the compatibility list before purchasing to ensure proper fitment.
• Why would I need different bushing thicknesses for my RC buggy? — Different caster angle settings suit different track conditions and driving preferences. A thinner bushing (0.5mm) gives quicker steering and suits tight technical tracks, while a thicker bushing (2.5mm) provides more stability and suits faster, more open tracks. Having all three sizes in one kit lets you experiment and find the optimal setup for your local track or driving style without purchasing multiple part numbers.
• How do I know which caster bushing thickness to use? — Start with the 1.5mm bushing as a baseline setup, then test with thinner bushings if you want more responsive steering, or thicker bushings if you need more stability at speed. Many racers keep all three sizes on hand so they can quickly adjust their setup between heats or practice sessions based on how the track is playing and how your driving feels.
• Are these genuine Team Associated parts? — Yes, these are OEM Team Associated components manufactured to the exact specifications of the brand's original equipment. Using genuine Team Associated spare parts ensures perfect fitment, reliable performance and compatibility with your buggy's suspension system.
• Will these bushings improve my RC buggy's performance? — Caster angle adjustment is one of the most effective suspension tuning methods in RC racing. Properly dialled caster angle can significantly improve steering response, cornering grip, stability and overall handling. These bushings give you the tool to make those critical adjustments without complete suspension rebuilds.
• Do I need special tools to install these bushings? — No, these bushings are straightforward to install using standard RC tools. Most installations require only basic hex wrenches and a few minutes of work, making them ideal for weekend maintenance or between-race adjustments.
