Team Associated 13mm Rear Shock Springs 1.8 lb/in Green AS91947

Overview

The Team Associated 13mm Rear Shock Springs in green are precision-engineered suspension components designed for racers and RC enthusiasts looking to fine-tune the handling characteristics of their Team Associated RC vehicles. These aftermarket shock springs deliver a 1.8 lb/in spring rate, offering the perfect balance for adjusting your RC car's suspension geometry and ride height. Whether you're competing in a local RC racing event, enjoying weekend bashing sessions, or preparing your RC buggy or truck for serious track work, these genuine Team Associated springs provide the performance upgrade you need. Available at RC Model Shop, these springs are an essential upgrade for anyone serious about optimising their RC car's suspension setup in the UK RC hobby market.

With their distinctive green colour coding, these 13mm rear shock springs make it instantly easy to identify them within your suspension system and match them with other components in your typical RC suspension setup. The colour-coded design is not just for aesthetics—it's a practical feature that helps you organise your spare parts collection and ensures you're using the correct spring rate for your specific vehicle setup. These springs are compatible with multiple Team Associated models, making them a versatile option for owners of B6.4D, B6.4, B74.2D, B74.2, B7, and B7D platforms, though they serve as option parts that allow you to customise your vehicle to suit your driving style and track conditions.

As an option part in the Team Associated range, these rear shock springs represent the kind of detailed tuning capability that separates competitive RC racing from casual driving. The 1.8 lb/in rate sits in the mid-range of available options, making it suitable for drivers who want a responsive suspension without excessive softness or harshness. Whether you're dealing with smooth concrete racing surfaces at your local RC track, bumpy outdoor terrain, or variable conditions across different race venues, adjusting your spring rates is one of the most effective ways to dial in your vehicle's handling. By swapping to these green 1.8 lb/in springs, you're taking control of your RC car's performance and tailoring it specifically to your preferences.

Frequently Asked Questions

• What does the 1.8 lb/in spring rate mean for my RC car's performance? — The spring rate indicates how much force is required to compress the spring by one inch. A 1.8 lb/in rate is considered a medium spring, offering balanced compliance for both smooth tracks and bumpy terrain. Lower spring rates (softer) provide more suspension travel and absorption of large impacts, whilst higher rates (stiffer) improve stability and cornering precision. The 1.8 lb/in specification makes these ideal for drivers seeking versatility across different track conditions and setups.
• Are these springs suitable for beginners learning RC racing? — Yes, absolutely. Beginners benefit from starting with medium spring rates like the 1.8 lb/in specification because they provide forgiving suspension characteristics that are less sensitive to setup mistakes. As you progress and understand how suspension tuning affects your vehicle's handling, you can experiment with softer or stiffer springs to dial in performance. Starting with these green springs gives you a solid baseline from which to learn the fundamentals of suspension tuning.
• How do I know if I need to change my shock springs? — You should consider changing spring rates if your RC car exhibits specific handling problems: if the suspension feels too soft and the vehicle wallows through corners or bounces excessively, you need stiffer springs; if it feels harsh and loses traction over bumps, you might benefit from softer springs like these 1.8 lb/in units. Experimenting with spring rates is one of the best ways to learn how suspension geometry affects your RC car's on-track behaviour.
• What Team Associated models are compatible with these springs? — These 13mm rear shock springs are compatible with Team Associated B6.4D, B6.4, B74.2D, B74.2, B7, and B7D platforms. Always verify your specific vehicle's shock absorber diameter before purchasing to ensure compatibility. If you're unsure about your model, our experienced RC specialists at RC Model Shop are happy to help identify the correct parts for your vehicle.
• What is the difference between L61, 11.5T, and 1.2D specifications? — These are technical measurements of the spring's physical characteristics: L61 represents the compressed length of the spring, 11.5T indicates the number of turns in the coil, and 1.2D refers to the wire diameter. Together, these specifications determine the spring's performance characteristics and ensure consistent quality and compatibility across production batches.
• How often should I replace these shock springs? — Quality shock springs like these Team Associated units can last many race sessions if properly maintained. However, springs gradually lose their tension over time due to repeated compression cycles. If you notice your suspension sitting lower than before or feeling softer than when new, it's time to replace the springs. Most competitive racers keep spare spring sets for different track conditions, rotating them throughout the season.
