Overview
The HoBao EPX Shock Springs (4) 28mm 2kgf/cm represent essential suspension tuning components for owners of HoBao's popular Hyper EPX 1/10 scale RC truck range. These genuine OEM spare parts are specifically engineered to deliver precise suspension geometry and handling characteristics that HoBao designers intended, making them an excellent choice for RC enthusiasts in the UK who demand reliable, performance-focused components for their RC vehicles. Whether you're a weekend basher enjoying your RC car UK hobby or someone looking to maintain factory-specification performance, these shock springs provide the upgrade path and replacement solution you need.
Suspension tuning is one of the most effective ways to improve your RC truck's handling, stability and overall driving experience. The correct spring rate directly influences how your vehicle responds to terrain changes, maintains traction during acceleration and braking, and maintains consistent ride height. These genuine HoBao springs are manufactured to exacting standards and paired with the correct spring rate of 2kgf/cm, they deliver predictable, repeatable performance that makes your RC model respond exactly as engineered.
As an authorised HoBao dealer serving the UK RC community, RC Model Shop stocks genuine spare parts that guarantee compatibility and reliability. These shock springs are a popular consumable item in the world of RC car UK ownership, and having a spare set on hand ensures you can quickly swap in fresh components should you wish to experiment with different suspension setups or when original springs show signs of wear or damage from extended use.
Key Features
- Set of four springs — You receive a complete set of four shock springs, providing springs for both front and rear shock absorbers on your HoBao Hyper EPX 1/10 truck, ensuring matched performance across the entire suspension system.
- 28mm length specification — The 28mm length dimension is precisely engineered for HoBao Hyper EPX vehicles, ensuring correct shock stroke and suspension geometry for optimal handling characteristics and ride quality.
- 2kgf/cm spring rate — This specific spring stiffness rating of 2kgf/cm is the OEM specification for HoBao Hyper EPX models, providing the ideal balance between responsive handling and bump compliance for both on-road and light off-road use.
- Genuine HoBao manufacture — As official OEM parts, these springs carry the engineering credibility of HoBao's design team and manufacturing expertise, ensuring they meet precise standards for consistency and durability.
- Direct compatibility with Hyper EPX models — These springs are specifically designed for seamless fitment with all variants of the HoBao Hyper EPX 1/10 Cab Truck Roller, including models with Yellow, Pearl White and Clear body options.
- Essential suspension maintenance component — Springs are wear items that lose tension over time, making these spares essential for anyone running their HoBao EPX regularly and wanting to maintain factory suspension performance.
Technical Performance
The HoBao EPX Shock Springs deliver engineering excellence in a compact package. At 28mm in length with a spring rate of 2kgf/cm, these components are engineered to work in harmony with the Hyper EPX's suspension geometry, which features modern independent double-wishbone design both front and rear. The 2kgf/cm spring rate represents a balanced specification suitable for the HoBao Hyper EPX's intended use case as a versatile 1/10 scale truck platform. This stiffness level provides sufficient support to maintain ride height under load and during dynamic cornering, whilst remaining compliant enough to absorb bumps and surface irregularities without harshness. The springs are manufactured from high-quality steel alloy, heat-treated to precise specifications to ensure consistent spring rate over thousands of compression and extension cycles. When properly installed in HoBao's shock absorbers alongside compatible dampers, these springs contribute to balanced front-to-rear weight distribution and neutral handling characteristics. The engineering tolerances are tight, ensuring that all four springs in this set deliver virtually identical performance, preventing handling imbalances that can occur with mixed spring rates or worn components.

Frequently Asked Questions
- Are these shock springs compatible with all HoBao Hyper EPX models? — Yes, these genuine OEM springs are designed for all variants of the HoBao Hyper EPX 1/10 Cab Truck Roller, including the Yellow Body (HB-GPX4E-Y), Pearl White Body (HB-GPX4E-W) and Clear Body (HB-GPX4E-CL) versions, as they all share identical suspension geometry and shock mounting specifications.
- When should I replace my shock springs? — Shock springs should be inspected regularly for signs of fatigue, permanent deformation or loss of tension. Springs typically remain serviceable for extended periods, but regular users may want to refresh them every 12-24 months depending on usage intensity, or whenever you notice changes in ride height, excessive body roll during cornering, or reduced responsiveness to terrain.
- What is the difference between 2kgf/cm and other spring rates? — Spring rate is measured in kgf/cm, indicating how many kilograms of force is required to compress the spring by one centimetre. A higher rating (e.g. 3kgf/cm) creates a stiffer suspension better for high-speed bashing, whilst a lower rating (e.g. 1.5kgf/cm) produces a softer suspension with better bump absorption on rough terrain. The 2kgf/cm specification on your HoBao EPX represents the factory OEM choice for balanced, predictable handling.
- Can I use different spring rates on the front and rear? — Whilst it's theoretically possible to experiment with mixed spring rates, HoBao engineers the EPX around matched spring rates front and rear for neutral handling balance. Using different rates can create handling bias, so we recommend maintaining the factory 2kgf/cm specification for both ends unless you have advanced tuning knowledge.
- Are these springs suitable for beginners? — Yes, absolutely. These are genuine OEM parts at the factory specification, making them the perfect choice for beginner and intermediate RC car UK enthusiasts. They deliver the handling balance and reliability that HoBao intended, allowing new drivers to focus on developing skills rather than troubleshooting suspension issues.
- How do I know if I need to replace my springs? — Signs that your springs may need replacement include visible permanent deformation, the vehicle sitting lower than normal when stationary, excessive body roll during turns, or the rear end feeling loose and unpredictable. If you can't compress the springs easily by hand or they feel unequal when cycling the suspension by hand, replacement is advisable.
