Overview
The Associated 12mm Big Bore Spring 54mm 4.10Lb (AS91636) is an essential suspension component for RC enthusiasts in the UK who demand precision tuning and optimal handling performance. This genuine Team Associated spare part provides a 4.10 lb spring rate specifically engineered for 12mm big-bore shock applications, making it an indispensable upgrade for anyone serious about maximising their RC car's suspension response. Whether you're competing on the track or simply looking to fine-tune your RC vehicle for different surface conditions, this spring offers a straightforward yet effective solution for suspension customisation across a range of Team Associated platforms.
Designed with the RC model car enthusiast in mind, the AS91636 spring helps you achieve the perfect balance between ride height and handling characteristics. This is particularly valuable when transitioning between different track surfaces or adjusting your setup for seasonal changes. Short course truck and stadium truck owners will find this spring especially useful, as it allows for precise suspension geometry adjustments that can dramatically affect cornering stability, acceleration grip and overall driving feel. The 54mm length and 4.10 lb spring rate provide a middle-ground option that works well for general-purpose tuning, making this an excellent choice for RC car UK enthusiasts who want reliable, proven performance without unnecessary complexity.
As an authorised Team Associated retailer, RC Model Shop stocks this genuine spare part to ensure you receive exactly the component your RC vehicle needs. The AS91636 spring is compatible with several popular Team Associated models including the RC10SC5M, RC10T4.2 and RC10T5M, making it a must-have addition to any spares box for owners of these platforms.

Technical Performance
The Associated 12mm Big Bore Spring 54mm 4.10Lb represents precision engineering at its finest, combining proven suspension dynamics with the specific dimensional requirements of Team Associated's big-bore shock systems. At 54mm in length, this spring provides the optimal working range for 12mm bore diameter shocks, ensuring that your suspension operates within its designed parameters for maximum responsiveness and longevity. The 4.10 pound-force spring rate sits in the moderate range, making it suitable for a wide variety of track conditions and driving styles. This rating is soft enough to maintain good traction and bump compliance on rough surfaces, yet stiff enough to resist excessive compression during aggressive cornering and acceleration. The engineering behind this component reflects Team Associated's reputation for producing components that deliver predictable, repeatable performance—essential qualities for both casual RC enthusiasts and serious competitors. Built to exacting standards from materials selected for durability and consistent performance characteristics, this spring will maintain its rate stability across countless driving sessions, ensuring your suspension tuning remains reliable and effective.

Frequently Asked Questions
- Will this 12mm big-bore spring fit my Team Associated RC car? — This spring is specifically designed for 12mm big-bore shock applications and is confirmed compatible with the RC10SC5M, RC10T4.2 and RC10T5M. Before purchasing, confirm your vehicle uses 12mm big-bore shocks and that you need a 54mm length spring. If you're unsure about your shock type or length, we recommend contacting our expert team at RC Model Shop—we're happy to help you identify the correct component for your setup.
- What does the 4.10 Lb spring rate mean? — The 4.10 Lb rating refers to how much force is required to compress the spring by one inch. A lower rate (softer spring) compresses more easily and provides better traction on rough surfaces, whilst a higher rate (stiffer spring) resists compression for more stable handling on smooth tracks. The 4.10 Lb rate is considered moderate and works well for general-purpose driving and track tuning.
- How do I know if this spring will improve my RC car's handling? — Spring selection depends on your current setup and track conditions. If your vehicle feels too bouncy or unstable, a stiffer spring may help. If it feels too stiff or loses traction, a softer spring might improve grip. This AS91636 spring offers a balanced rate suitable for most conditions, but you may want to experiment with softer or stiffer alternatives depending on your specific track surface and driving style. We recommend keeping multiple spring rates in your spares box to dial in the perfect setup.
- Can I use this spring on different Team Associated models? — This spring is confirmed compatible with RC10SC5M, RC10T4.2 and RC10T5M models. However, Team Associated makes numerous platforms with different shock designs. Before purchasing for a different model, confirm it uses 12mm big-bore shocks of the correct length. Our experienced team at RC Model Shop can help you verify compatibility if you're unsure.
- Is this a genuine Team Associated part? — Yes, the AS91636 is an official Team Associated spare part manufactured to the brand's exact specifications. When you purchase from RC Model Shop, you receive genuine, authentic components backed by Team Associated's quality assurance and our retailer guarantee.
- What other springs should I have in my spares box? — Serious RC competitors typically maintain a range of spring rates to suit different conditions. If you use the 4.10 Lb spring, you might also consider stocking softer options (such as 3.60 Lb) for high-grip surfaces and stiffer options (such as 4.60 Lb) for slippery conditions. Having multiple rates allows you to quickly adapt to changing track conditions without waiting for delivery.
