Key Features

• Precision 3.6 lb/in Spring Rate — This carefully selected spring rate provides a balance between responsive handling and bump absorption, making these springs suitable for a wide range of track conditions and driving styles across UK RC racing venues. A lower spring rate like this 3.6 lb/in specification allows for better suspension compliance and traction, particularly beneficial on rough or uneven track surfaces where the chassis needs to maintain ground contact.
• 13mm Shock Diameter — The 13mm diameter is the standard specification for these Team Associated models, ensuring perfect fitment without modification. This standardised sizing means you can confidently order replacements knowing they will install directly into your existing shock towers without compatibility issues or fitment problems.
• L44 Length Specification — The L44 length designation ensures optimal suspension geometry and ride height for the intended platforms. This specific length measurement is critical for maintaining the correct suspension angles and preventing binding during full compression or extension of the shock absorber assembly.
• 6.75 Coil Turns (6.75T) — The number of coils directly influences the spring rate and the overall compression characteristics of the shock. With 6.75 turns, these springs deliver the specified 3.6 lb/in rate across the full range of suspension travel, providing consistent damping feedback as your RC car compresses and extends over obstacles and bumps.
• 1.2D Wire Diameter Specification — The 1.2mm wire diameter (1.2D) represents a medium-gauge specification that balances durability with the precise spring rate required for competitive RC racing. This wire thickness ensures the springs will withstand repeated compression cycles without permanent deformation, maintaining their performance characteristics throughout a full racing season.
• Blue Colour Coding — The distinctive blue colour allows for instant visual identification of these 3.6 lb/in springs, preventing confusion during setup changes and helping you maintain an organised spares inventory. In the fast-paced environment of RC racing, where every moment counts between heats, colour-coded components save valuable time and reduce the risk of accidentally installing the wrong spring rate.
• Option Part Compatibility — These springs are designed as option parts rather than standard-issue components, meaning they offer an upgrade path or alternative tuning choice for drivers seeking to explore different suspension characteristics. This compatibility across multiple Team Associated models, including the B6.4, B6.4D, B74.2, B74.2D, B7, and B7D, makes them a valuable addition to any Team Associated RC car owner's workshop.
• Repeatable Suspension Setup — The clearly marked specifications (spring rate, length, coil count, and wire diameter) make setup changes straightforward and repeatable, helping you maintain a balanced and predictable chassis geometry from session to session. This repeatability is essential for competitive racing, where consistent performance across multiple heats determines championship outcomes.

Technical Performance

The Team Associated 13mm Front Shock Springs AS91942 represent a carefully engineered suspension component that balances theoretical suspension design with practical racing requirements. The 3.6 lb/in spring rate falls into the softer range of front shock springs, making these particularly well-suited to track conditions that demand compliance and traction retention. The spring rate — measured in pounds-force per inch of compression — directly determines how quickly the spring resists compression as your RC car encounters bumps, kerbs, and track irregularities. A 3.6 lb/in specification means the spring applies 3.6 pounds of force for every inch of compression, providing a softer initial response compared to stiffer springs rated at 4.5 or 5.5 lb/in. This softer spring rate is particularly advantageous on rough tracks or when running lower ride heights, as it allows the suspension to absorb impacts more fully before transferring energy to the chassis. The engineering behind the 6.75-turn specification creates a spring with excellent linearity throughout its compression range, meaning the spring rate remains consistent whether the shock is compressed slightly for a small bump or fully compressed for a major impact. The 1.2mm wire diameter (1.2D specification) represents a deliberate engineering choice that balances spring longevity with suspension responsiveness. Thicker wires (1.4mm or 1.6mm) would create stiffer springs, whilst thinner wires would risk permanent deformation and loss of spring rate over time. The L44 length specification is equally critical — this measurement ensures that the spring compresses and extends within the designed shock tower geometry, preventing binding at full compression and ensuring the spring maintains its intended preload at full extension. For UK RC racers using Team Associated competition platforms, these springs are manufactured to the same exacting standards that apply across the full Team Associated product line, with quality control measures ensuring batch-to-batch consistency. The blue colour coding isn't merely aesthetic — it represents a visual confirmation of the 3.6 lb/in specification, reducing the risk of installation errors during time-critical pit stops or practice session adjustments. These springs are designed to withstand thousands of compression cycles across an entire racing season without permanent set or loss of spring rate, provided they are stored correctly and not exposed to extreme heat or UV exposure.

Frequently Asked Questions

• What is the difference between 3.6 lb/in and stiffer front shock springs for Team Associated RC cars? — The 3.6 lb/in spring rate is softer than alternatives like 4.5 or 5.5 lb/in specifications, meaning it compresses more readily in response to bumps and track imperfections. This softer rate provides better traction and suspension compliance on rough surfaces, whilst stiffer springs offer more aggressive handling and higher ride heights preferred on smooth, flowing tracks. For most UK track conditions and general-purpose RC racing, the 3.6 lb/in rate offers an excellent balance between traction and chassis responsiveness.
• What Team Associated RC car models are these front shock springs compatible with? — These springs are listed as option parts for the Team Associated B6.4, B6.4D, B74.2, B74.2D, B7, and B7D platforms. Before ordering, confirm your exact model to ensure compatibility. The 13mm diameter and L44 length are standard for these platforms, but it's always wise to verify your specific chassis specification before purchasing suspension components.
• How often should I replace my front shock springs? — With proper maintenance and storage, high-quality Team Associated shock springs like these can maintain their spring rate for an entire racing season or longer, depending on usage intensity. If you notice that your RC car's ride height is increasing over time, or if the suspension feels notably softer than expected, this may indicate spring fatigue or permanent set — a sign that replacement springs should be considered. Competitive racers often carry spare springs in their pit kit to allow for mid-season tuning adjustments.
• Can I mix different spring rates on the front and rear of my RC car? — Yes, and this is actually a common tuning practice. Many RC racers run softer front springs (like this 3.6 lb/in specification) paired with stiffer rear springs to achieve a specific handling balance. This front-biased soft setup promotes traction and mid-corner bite, whilst the stiffer rear springs help with overall platform support and prevent excessive squat during acceleration.
• What does the L44 length specification mean? — The L44 designation refers to the specific compressed and extended length of the shock spring assembly. This measurement is critical for maintaining correct suspension geometry, ride height, and shock tower clearance. Installing springs with different length specifications could result in binding, poor suspension action, or chassis geometry problems.
• Are these shock springs suitable for beginners? — Yes, absolutely. These Team Associated springs are option parts used across multiple models from entry-level to competition-grade RC cars. The 3.6 lb/in rate is considered a moderate specification, making it suitable for drivers learning about suspension tuning without requiring specialist knowledge. Many UK RC hobby retailers recommend starting with this spring rate as a baseline, then experimenting with stiffer or softer alternatives as you develop your understanding of how suspension affects vehicle behaviour.
• Why is the colour coding important for shock springs? — The blue colour acts as a visual indicator of the 3.6 lb/in spring rate, helping you quickly identify the correct springs during pit stops, maintenance sessions, and workshop organisation. In the organised chaos of an RC racing event, where you might be managing multiple spring rates across different vehicles or testing various configurations, colour-coded components save critical minutes and reduce installation errors.
• How do I know when shock springs need replacing? — Quality Team Associated springs should maintain their rate for extended periods, but visible signs of wear, permanent bend, rust, or a noticeable change in your RC car's ride height indicate replacement is needed. Springs that have been exposed to extreme heat (such as from prolonged storage in hot vehicles or sheds) may also lose their spring rate prematurely.
