• Rear Shock Spring Design — Engineered specifically for rear suspension applications, this spring works in conjunction with your shock absorber to control ride height, support weight distribution, and maintain consistent contact with the track surface throughout aggressive cornering and jumps.
• Easy Part Identification — The clearly marked part number AS81219 makes it simple to identify and order exactly what you need, eliminating confusion when sourcing replacement components for your RC8B3 or compatible buggy models.

Technical Performance

The Associated Rear Spring AS81219 is manufactured using high-quality steel and precision engineering to ensure consistent performance across multiple heat cycles and extended use. With a spring rate of 4.3 lb/in, this component provides moderate compliance that absorbs bumps and track imperfections whilst maintaining enough support to keep your RC8B3 buggy planted during high-speed cornering and acceleration. The spring works as part of a complete suspension system where spring rate, shock damping, and anti-roll bar settings all interact to create your vehicle's overall handling character. This 4.3 lb/in rate sits in the middle of the suspension tuning spectrum, making it an excellent choice for drivers who want balanced handling without needing to invest in multiple spring kits to find their sweet spot. The rear spring is critical for maintaining consistent ride height and preventing chassis bottoming, both of which are essential for maintaining traction and preventing damage to expensive RC components. Whether you're running the RC8B3 in its standard kit configuration or have upgraded other suspension components, this spring will integrate seamlessly with your existing setup and provide the performance characteristics you've come to expect from genuine Associated parts.

Frequently Asked Questions

• What is the spring rate and how does it affect my RC buggy's performance? — The AS81219 features a 4.3 lb/in spring rate, which represents a balanced, medium compliance that works well across various track conditions. A softer spring rate (lower number) provides more cushioning and traction on rough surfaces, whilst a stiffer spring rate (higher number) offers more support and stability during high-speed driving. The 4.3 lb/in rate is versatile enough for both racing and recreational bashing, making it an excellent choice if you're unsure which spring rate to choose for your RC8B3.
• Will this spring fit my RC8B3 buggy? — Yes, this is a genuine Associated rear shock spring designed specifically for the RC8B3 kit buggy. It is also compatible with several other Associated RC8 series models including the RC8B3e, RC8T3, RC8T3e, and RC8B3.1 variants, making it a versatile spare part for anyone running these vehicles. Always verify your vehicle model before ordering to ensure compatibility.
• How do I know when to replace my rear spring? — Springs should be replaced if they become visibly bent, cracked, or damaged, or if you notice your vehicle sits lower than it should (indicating a weak or fatigued spring). Springs can also lose their rate over time with extended use, which would result in your car bottoming out more easily or feeling less planted. Having spare springs on hand allows you to experiment with different rates to optimise your suspension setup.
• What other spring rates are available for the RC8B3? — Associated produces multiple spring rates for their RC8B3 range to suit different preferences and driving styles. The 4.3 lb/in rate offers a balanced middle ground, but softer and stiffer options are available. Experimenting with different spring rates is an important part of RC tuning, and swapping springs is one of the easiest ways to dramatically change how your buggy feels without major modifications.
• Can I use this spring on my RC8T3 or other Associated models? — The AS81219 rear spring is listed as compatible with RC8B3, RC8B3e, RC8T3, RC8T3e, and RC8B3.1 models. However, we recommend verifying compatibility with your specific vehicle variant before purchase, as some models may have different suspension geometry that could affect spring performance. Contact our knowledgeable team if you're unsure about compatibility with your particular RC car.
• Is this a genuine Associated part? — Yes, the AS81219 is a genuine OEM part manufactured by Team Associated to the same specifications and quality standards as springs fitted to factory-fresh RC8B3 kits. This ensures perfect fitment, reliable performance, and compatibility with all genuine Associated suspension components. We only stock authentic parts from authorised distributors.
