HoBao Hyper ST Shock Springs Front and Rear 90mm 1kgf/cm H86047

Overview

The HoBao Hyper ST Shock Springs F/R 90mm 1kgf/cm (H86047) are premium front and rear shock spring replacements designed specifically for the HoBao Hyper ST Truggy platform. These genuine OEM springs are essential maintenance and tuning components for RC enthusiasts who demand consistent performance from their truggy. Whether you're running the HoBao Hyper ST Truggy RTR or the more advanced HBM7-ST-PRO model, these shock springs deliver the responsive handling and stability that serious RC drivers expect from a competition-grade truggy suspension system.

As a UK RC car enthusiast, you'll appreciate the importance of quality suspension components in your truggy setup. The HoBao Hyper ST has become a favourite among UK RC drivers and bashers alike, thanks to its robust construction and excellent handling characteristics. When your existing shock springs lose their stiffness through wear or if you want to experiment with different spring rates for varying track conditions, the HoBao Hyper ST Shock Springs F/R provide an affordable and effective upgrade path. These springs are specifically engineered to match the geometry and performance characteristics of the Hyper ST platform, ensuring optimal weight distribution, cornering grip and ride quality across both tarmac and off-road surfaces.

Finding the right shock springs for your RC truggy UK setup can make the difference between mediocre handling and truly responsive, predictable performance. The HoBao Hyper ST Shock Springs F/R are manufactured to exacting standards by HoBao, the respected Japanese RC manufacturer known for producing high-quality suspension components. At RC Model Shop, we stock genuine HoBao parts to ensure your Hyper ST truggy performs at its best, whether you're racing competitively or enjoying weekend bashing with friends.

Key Features

• Front and Rear Spring Set — This package includes springs for both front and rear shock absorbers, allowing you to refresh or upgrade your entire suspension system in one purchase. Having matched pairs ensures consistent suspension geometry and handling balance across the truggy's chassis.
• 90mm Length — The 90mm dimension is specifically engineered for the HoBao Hyper ST platform, ensuring proper shock stroke and suspension travel. Using the correct spring length is critical for maintaining the designed suspension geometry and preventing binding or excessive compression.
• 1kgf/cm Spring Rate — This moderate spring rate (1 kilogram-force per centimetre) provides a balanced setup suitable for general driving, bashing and moderate racing applications. The spring rate determines how quickly the suspension compresses under load, affecting traction, stability and ride comfort on different surfaces.
• Genuine HoBao Manufacturing — These are authentic OEM components produced by HoBao using quality materials and manufacturing processes. Original equipment springs ensure perfect fitment, longevity and performance characteristics that match your truggy's suspension design.
• Compatible with Hyper ST Models — Specifically designed for the HBM7-ST-PRO and HBM7-ST variants of the HoBao Hyper ST Truggy, guaranteeing correct fitment without modification. Using manufacturer-specified components eliminates guesswork and compatibility issues.

Technical Performance

The HoBao Hyper ST Shock Springs F/R represent a critical component of the overall suspension system engineering found in the Hyper ST platform. Spring stiffness, measured in the spring rate of 1kgf/cm, directly influences how the suspension responds to bumps, braking loads and cornering forces. A properly matched spring rate ensures the shock absorber and spring work in harmony, compressing smoothly under acceleration and weight transfer whilst maintaining sufficient support to prevent bottoming out on large impacts or during aggressive driving. The 90mm length is precisely calculated to provide the correct mounting geometry within the HoBao Hyper ST's shock tower design, maintaining the anti-squat and anti-dive characteristics engineered into the chassis. Quality materials in these springs ensure they maintain their stiffness over extended periods of use, unlike inferior aftermarket springs that can weaken and become mushy after hours of driving. The front and rear pairing allows drivers to maintain suspension balance, which is essential for predictable handling in both acceleration and braking scenarios. Whether you're running your Hyper ST on tarmac surfaces for high-speed racing or across rougher terrain for bashing, these shock springs will provide the consistent response and support needed for confident driving.

Frequently Asked Questions

• Are these shock springs compatible with my HoBao Hyper ST Truggy? — Yes, these H86047 springs are specifically designed for the HoBao Hyper ST platform. They are compatible with both the HBM7-ST-PRO and HBM7-ST RTR models. Always verify your exact model before purchase to ensure correct fitment.
• What does the 1kgf/cm spring rate mean? — The spring rate of 1kgf/cm (kilogram-force per centimetre) indicates how much force is required to compress the spring by one centimetre. A softer spring (lower kgf/cm rating) compresses more easily and provides a plush feel but may bottom out under hard impacts, whilst a stiffer spring (higher kgf/cm rating) is more resistant to compression but can feel harsh on rough surfaces. The 1kgf/cm rate on these HoBao springs is a moderate, balanced setting suitable for mixed-use driving.
• Do I need to replace both front and rear springs? — Whilst you can replace springs individually if only one is damaged or weakened, it is recommended to replace both front and rear springs as a matched pair. This ensures your truggy maintains suspension balance and consistent handling characteristics across all driving conditions. Using springs of different ages or stiffness values will result in unpredictable handling and potential performance issues.
• How often should I replace shock springs on my RC truggy? — Shock springs will gradually lose their stiffness over time through repeated compression cycles, especially with frequent or aggressive driving. If your truggy's suspension feels softer than when new, if the chassis bottoms out more easily, or if handling feels less responsive, it may be time to replace your springs. Regular inspection during routine maintenance is recommended, and replacement springs should always be on hand for serious RC competitors.
• Can I use different spring rates for tuning? — Yes, many RC drivers experiment with different spring rates to tune their truggy's handling for specific track conditions or driving styles. Softer springs may improve traction on bumpy terrain, whilst stiffer springs can help prevent bottoming on smooth tracks. However, for the best results, consult HoBao's setup guides or experienced UK RC retailers to ensure your chosen spring rate suits your intended application.
• What is the difference between front and rear springs? — Whilst both springs in this set have the same 1kgf/cm rate, the front and rear positions in a truggy experience different loading conditions due to weight transfer during acceleration and braking. Many advanced drivers run different spring rates front and rear (available separately from HoBao) to optimise handling balance, but this matched pair provides an excellent starting point for drivers seeking straightforward, balanced performance.
