Key Features

• 3.30 lb Spring Rate — This mid-range spring rate provides a balanced compromise between soft and stiff characteristics, offering increased chassis roll for better traction in bumpy conditions whilst maintaining sufficient responsiveness for technical track sections and high-speed sections.
• White Colour Coding — Team Associated's industry-standard colour-coding system allows you to instantly identify this 3.3lb spring at a glance, making it easy to maintain multiple setups and ensuring you never mix up spring rates during tuning sessions or track days.
• 12mm Big Bore Shock Compatibility — Engineered exclusively for use with Team Associated's 12mm Big Bore Shock Set (sold separately), this spring integrates perfectly with optional shock hardware on compatible platforms, delivering smooth suspension action across rough terrain.
• Precision Suspension Tuning — Part of a complete 10-step spring rate system (ranging from 2.85 lb brown through to 4.20 lb purple), this 3.3lb white spring allows racers and bashers to make fine adjustments to chassis handling without needing a complete suspension overhaul.
• Genuine Associated Engineering — Manufactured to exacting standards by Team Associated, this replacement spring maintains the quality and consistency that Team Associated competition vehicles are famous for, ensuring predictable handling across multiple runs and sessions.

Technical Performance

The Associated 12mm Big Bore Front Spring represents the culmination of decades of Team Associated suspension engineering expertise. Constructed from high-quality spring steel, this component is designed to maintain its rate characteristics across hundreds of usage cycles, delivering consistent performance whether you're running on asphalt tracks, clay circuits, grass fields, or rough off-road terrain. The 3.30 lb rate positions this spring perfectly in the middle of the available range, making it an excellent starting point for drivers transitioning between softer and stiffer setups. When installed in the Big Bore Shock Set, this spring delivers smooth, controlled suspension action that absorbs bumps and impacts whilst maintaining sufficient spring force to keep the chassis planted during aggressive cornering and high-speed sections. The spring's performance characteristics change the vehicle's handling balance predictably: softer springs increase chassis roll and traction whilst making the vehicle more prone to bottoming out in extreme conditions, whilst stiffer springs decrease roll and traction but increase overall responsiveness. This 3.3lb rate offers balanced characteristics ideal for mixed-terrain driving and general competition use. Compatible with all Team Associated B-series buggies (B4, B4.1, B4.2, B44, B44.1, B44.2), T-series touring cars (T4, T4.1, T4.2), and SC-series short course trucks (SC10, SC10.2, SC10GT), this front spring is a versatile upgrade component for any serious RC car UK enthusiast building a competition setup.

Effects of Shock Spring Changes

• Softer Springs — Increased chassis roll, increased traction, better performance in bumpy conditions, but more likely to bottom out under extreme compression
• Stiffer Springs — Decreased chassis roll, decreased traction, increased responsiveness and sharper turning characteristics

Frequently Asked Questions

• Which Team Associated vehicles use 12mm Big Bore Front Springs? — This spring is compatible with Team Associated SC10, SC10.2, SC10GT, RC10B4 series (B4, B4.1, B4.2), RC10B44 series (B44, B44.1, B44.2), and RC10T4 series (T4, T4.1, T4.2) when equipped with the optional Big Bore Shock Set. Your vehicle must have the 12mm Big Bore shocks installed to use this front spring.
• What does the 3.3lb rating mean and how does it affect performance? — The 3.3 lb (or 3.30 lbs) rating indicates the spring rate, measured in pounds of force per inch of compression. A higher number means a stiffer spring. This 3.3lb white spring sits in the middle of the available range (2.85 lb to 4.20 lb) and offers balanced handling suitable for general competition and recreational driving. Softer springs provide more traction and compliance over bumps, whilst stiffer springs increase responsiveness and reduce chassis roll.
• How do I know which spring rate to choose for my RC car? — Start with this 3.3lb white spring if you're unsure, as it offers balanced characteristics. If your car feels too wallowy and rolls excessively, try a stiffer (higher number) spring. If it feels too stiff and bouncy, try a softer (lower number) spring. Weather and track conditions also matter: softer springs work better on bumpy terrain, stiffer springs on smooth tracks.
• Can I use this spring on other RC brands? — No, this spring is engineered specifically for Team Associated 12mm Big Bore shocks. Using it on other brands' shock systems may result in poor performance or damage. Always verify compatibility with your shock diameter before purchasing.
• What is the difference between 12mm and 13mm shocks? — The number refers to the shock body diameter in millimetres. 12mm shocks are slightly smaller and lighter, typically used on 1/10 buggy and truck platforms like the B-series and SC-series. 13mm shocks are larger and heavier, used on other platforms. Springs and components are not interchangeable between the two sizes.
• How often should I replace my front springs? — Springs typically last many hundreds of runs before losing their characteristics. Replace them if you notice inconsistent handling, if the spring becomes damaged or bent, or if you simply want to try a different spring rate for tuning purposes. Springs are wear items and should be inspected regularly.
• Is this suitable for beginners? — Yes, this 3.3lb spring is an excellent choice for beginners looking to upgrade their suspension. The balanced rate makes it forgiving whilst still providing good handling, and the colour-coding system helps you track your setup. However, you will need a compatible Team Associated vehicle with Big Bore shocks already installed.
• What tools do I need to install this spring? — Installation is straightforward and typically requires only the basic Allen keys that come with your Big Bore Shock Set. You may need to compress the spring slightly to fit the spring cup, which can be done by hand or with a simple spring compressor tool.
