Overview
The FTX Supaforza Rear Shock Spring 5T is a genuine OEM replacement suspension component designed specifically for the FTX Supaforza GT 1/7th scale brushless electric RC car. This high-quality rear shock spring is an essential spare part for anyone who owns or operates an FTX Supaforza GT, whether you're a serious RC enthusiast enjoying competitive racing or a weekend basher putting your RC car UK through its paces on local tracks and terrain. The Supaforza GT is a premium ready to run RC model, and maintaining it with genuine FTX parts ensures optimal performance and reliability.
When it comes to suspension tuning and maintenance for your brushless RC buggy or RC racing car, having access to quality replacement springs is crucial. The rear shock spring is a critical component of the suspension system, directly affecting how your RC car handles bumps, absorbs impacts, and maintains traction across various terrains. Over time, springs can weaken, lose their tension, or become damaged through aggressive driving, requiring replacement to restore your vehicle's original handling characteristics and performance levels.
The 5T spring rating indicates the spring stiffness specification, which affects how the suspension compresses and extends during driving. This particular spring is engineered to match the factory specifications of the FTX Supaforza GT 1/7th Brushless Electric RTR models, ensuring that when you install this replacement component, your RC car's suspension geometry and performance are restored to their original design parameters. Whether you're replacing a worn spring or upgrading your suspension setup, this genuine FTX part delivers the quality and reliability you need for consistent performance.
Key Features

Technical Performance
The FTX Supaforza Rear Shock Spring 5T is engineered to precise manufacturing tolerances to ensure consistent spring characteristics and reliable performance on the track or off-road terrain. As a suspension component for a 1/7th scale brushless electric RC vehicle, this spring is designed to work in harmony with the Supaforza GT's advanced suspension geometry and shock absorber assembly. The 5T rating defines the spring constant, which determines how much force is required to compress the spring a given distance. This specific rating has been selected by FTX engineers to provide the optimal balance between comfort over bumps and responsiveness during cornering and acceleration for the Supaforza GT platform. Whether you're running on smooth tarmac tracks, grass fields, or mixed terrain typical of RC racing in the UK, this spring will maintain consistent performance across a range of driving conditions. Springs can weaken over time through repeated compression cycles, UV exposure, and the physical demands of RC driving, which is why having genuine replacement springs available ensures you can keep your Supaforza GT performing at its best throughout its operational life.

Frequently Asked Questions
- Is the FTX Supaforza Rear Shock Spring 5T compatible with other FTX models? — This spring is specifically designed for the FTX Supaforza GT 1/7th Brushless Electric RTR models in both red and blue colour variants. While it may fit other models that share similar suspension architecture, FTX officially lists compatibility only with the FTX5494R and FTX5494B models. We always recommend checking your vehicle's manual or contacting our team to confirm compatibility before purchasing if you own a different FTX model.
- How do I know if my Supaforza GT needs new rear shock springs? — Signs that your rear shock springs need replacement include noticeable sagging of the rear suspension, reduced responsiveness over bumps, increased body roll during cornering, or if the springs have become visibly damaged or deformed. If your RC car UK feels less responsive or sits lower than when new, it's time to consider replacing the springs.
- Is this a direct replacement for the factory spring? — Yes, this is a genuine OEM FTX part with the part number FTX9589, designed as a direct replacement for the original rear shock spring on your Supaforza GT. Installation is straightforward and requires no modifications or adapters.
- Can I upgrade to a different spring rate for tuning purposes? — The 5T rating is the factory specification for the Supaforza GT. While suspension tuning is an advanced topic in RC racing, any changes to spring rates should be approached carefully as they affect handling, traction, and overall performance. We recommend contacting our experienced team at RC Model Shop if you're considering suspension modifications.
- What is the spring stiffness and how does 5T compare to other ratings? — The 5T designation indicates the spring stiffness specification. Lower numbers typically indicate softer springs (more suspension travel, softer ride), whilst higher numbers indicate stiffer springs (less suspension travel, firmer response). The 5T rating for the Supaforza GT provides the manufacturer's recommended balance for optimal performance on the vehicle.
- How long do shock springs typically last? — The lifespan of a shock spring depends on frequency and intensity of use. Casual weekend driving might see springs last many months, whilst competitive racing or aggressive bashing can wear springs more quickly. It's good practice to inspect your springs regularly and replace them when you notice any loss of performance or visible damage.
