Overview
The RC4WD 110MM King Off-Road Dual Spring Shocks Spring Assortment (Z-S1291) is an essential suspension tuning kit for RC enthusiasts who demand precision control over their vehicle's damping characteristics. Whether you're running an RC crawler, RC buggy, or any scale RC vehicle equipped with King Off-Road Dual 110mm Spring Shocks, this comprehensive spring assortment gives you the flexibility to fine-tune your suspension response for virtually any terrain and driving condition. Available from RC Model Shop, this product is perfect for serious RC hobbyists in the UK who want to optimise their vehicle's handling without investing in completely new shock assemblies.
The RC4WD spring assortment represents the philosophy of genuine scale RC engineering — understanding that suspension tuning is not a luxury, but a necessity for competitive performance and weekend bashing alike. By offering multiple spring rates in a single package, RC4WD has eliminated the frustration of purchasing springs individually. This is particularly valuable for UK RC car enthusiasts who compete in different environments, from muddy outdoor terrain to indoor carpet tracks, or who simply want to experiment with their setup to discover what works best for their driving style.
King Off-Road shocks are recognised globally for their quality and reliability, and this official spring assortment is engineered to maximise the potential of these premium components. Each spring is colour-coded for easy identification, and the entire kit is designed specifically for the King Off-Road Dual 110mm Spring Shocks (Z-D0065), ensuring perfect fitment and performance every single time.
Key Features
- Four Different Spring Rates Included — This assortment contains four distinct spring rates (2.0, 1.6, 1.1, and 0.4) plus colour-coded identification marking on the bottom of each spring, allowing you to quickly identify which rate you're using and swap springs for different driving conditions without confusion or time-wasting trial and error.
- Complete Set for One Pair of Shocks — The kit includes enough springs to outfit one complete pair of dual-spring shock absorbers, with four springs per rate, giving you genuine flexibility in suspension tuning without needing to purchase multiple assortments.
- Colour-Coded for Easy Identification — Each spring rate features a distinctive colour marking (Black for 2.0, Red for 1.6, White for 1.1, Yellow for 0.4) on the bottom of the spring, making it impossible to accidentally mix spring rates and ensuring you always know exactly what you're running in your RC vehicle.
- Direct Compatibility with King Off-Road Dual 110mm Shocks — These springs are engineered to fit the RC4WD King Off-Road Dual Spring Shocks (110mm Medium OD) model Z-D0065 perfectly, with no modifications, adapters, or workarounds required — simply install and enjoy optimised suspension response.
- Precision Engineering for Multiple Terrain Types — The range of spring rates (from 0.4 to 2.0) covers virtually every driving scenario imaginable, whether you're tackling soft terrain that requires a more compliant suspension, or hard-packed surfaces where stiffer springs improve responsiveness and reduce unwanted oscillation.
- Licensed King Off-Road Technology — RC4WD's official licence to manufacture King Off-Road products means these springs incorporate genuine King Off-Road engineering standards and quality control, ensuring you're getting authentic performance-enhancing components, not cheap imitations.
Technical Performance
The RC4WD 110MM King Off-Road Dual Spring Shocks Spring Assortment delivers precise suspension tuning through carefully engineered spring rates that modify how your shock absorbers respond to impacts, compression, and rebound. Each spring measures 46mm in length (1.81 inches) with an outer diameter of 17.7mm (0.7 inches) and an inner diameter of 14.7mm (0.58 inches), dimensions that are optimised for the dual-spring design of King Off-Road shocks. Weighing just 55 grams (1.94 ounces) per set, these springs are lightweight enough not to significantly impact your RC vehicle's weight distribution while remaining rigid enough to provide the consistent, repeatable performance demanded by serious RC enthusiasts. The stock spring rate is 0.8, and this assortment extends your tuning range both softer (0.4 rate) and significantly stiffer (up to 2.0 rate), allowing you to dial in the exact suspension behaviour your specific vehicle and driving style requires. Whether you're competing in timed RC racing events across UK tracks, bashing through natural terrain, or crawling over obstacle courses, the ability to adjust spring rates without replacing entire shock assemblies represents genuine value and engineering flexibility that separates premium RC components from budget alternatives.

Frequently Asked Questions
- What spring rates are included and which one should I start with? — This assortment includes spring rates of 0.4 (softest, marked yellow), 1.1 (marked white), 1.6 (marked red), and 2.0 (stiffest, marked black). The stock spring rate for King Off-Road Dual 110mm shocks is 0.8, which sits between the 0.4 and 1.1 rates included in this kit. If you're new to spring tuning, start with the 1.1 rate (white) and adjust from there based on how your vehicle feels — softer springs (lower numbers) for plush, compliant suspension that handles big hits well, or stiffer springs (higher numbers) for more responsive, precise handling on smooth surfaces.
- Will these springs fit my RC crawler or RC buggy? — Yes, but only if your vehicle is equipped with RC4WD King Off-Road Dual Spring Shocks in the 110mm medium OD size (model Z-D0065). These springs are specifically engineered for that shock design and will not fit other shock types. Check your shock assembly to confirm you have the correct King Off-Road model before ordering.
- How do I know which spring rate I'm currently running? — Each spring in this assortment has a small colour marking on the bottom that identifies its rate — Yellow for 0.4, White for 1.1, Red for 1.6, and Black for 2.0. This colour coding means you can instantly identify which springs are installed in your shocks without any guesswork.
- Can I mix different spring rates on the same vehicle? — Technically possible, but not recommended for most applications. Dual-spring shocks typically work best when both springs have the same rate, as mixing rates can create unpredictable suspension behaviour. However, some advanced tuners experiment with mixed rates to achieve specific handling characteristics — this is beyond beginner territory and requires careful testing.
- Is this suitable for beginners to RC off-road vehicles? — This product is best suited to intermediate and experienced RC enthusiasts who understand suspension tuning concepts. Beginners should master basic RC driving and vehicle maintenance before diving into spring rate experimentation. That said, if you own King Off-Road shocks and want to explore tuning, this is a safe, affordable way to learn how spring rates affect vehicle behaviour.
- What is the difference between spring rate numbers? — Spring rates measure the force required to compress a spring by a specific distance. A lower number (0.4) means the spring compresses more easily, providing a softer, more absorbent ride that's excellent for rough terrain and large bumps. A higher number (2.0) means the spring is stiffer and resists compression, keeping your vehicle's ride height more consistent and improving handling precision on smoother surfaces. The range from 0.4 to 2.0 in this assortment covers virtually every driving scenario.
