Overview
The Traxxas Springs, shock, Long (natural finish) (GTS) (0.47 rate) are precision-engineered suspension components designed specifically for the TRX-4 Long Arm Lift Kit. These high-quality shock springs are essential for anyone looking to optimise their RC crawler's handling characteristics and ride quality. Whether you're a dedicated RC enthusiast in the UK exploring advanced suspension tuning or a weekend basher seeking improved performance, these genuine Traxxas springs deliver the responsive control and durability you need for challenging terrain.
Built to exacting specifications by Traxxas, these long shock springs feature a natural finish and are custom-wound to provide precise suspension performance. The 0.47 rate makes them ideal for lighter vehicle configurations or for those seeking a more compliant ride that responds well to smaller bumps and obstacles. As a spare part included with the TRX-4 Long Arm Lift Kit, these springs are proven components trusted by RC car enthusiasts across the UK and beyond.
Upgrading or replacing your shock springs is one of the most effective ways to fine-tune your RC crawler's suspension behaviour. The Traxxas GTS spring range offers different rates to allow you to compensate for your vehicle configuration, driving style and terrain type, making these springs an excellent choice for competitive drivers and hobbyists alike.
Key Features
- 0.47 Rate Spring Constant — The progressive spring rate is custom-wound to provide responsive control for small bumps whilst progressively stiffening to absorb harder impacts, allowing your suspension to react appropriately across different terrain conditions and impact scenarios.
- Long Length Specification — These shock springs are specifically designed for use with the TRX-4 Long Arm Lift Kit, ensuring perfect compatibility and optimal suspension geometry for extended travel and improved articulation.
- Natural Finish — The natural finish construction is durable and reliable, providing excellent corrosion resistance for outdoor RC driving in various UK weather conditions.
- GTS Spring Technology — Traxxas GTS springs are engineered with progressive-rate winding, meaning they deliver softer initial compliance for small bumps and progressively stiffer support for larger impacts, giving you the best of both worlds in suspension tuning.
- Custom-Wound Engineering — Each spring is meticulously wound to precise specifications to ensure consistent performance and compatibility with your TRX-4 suspension system.
- Genuine Traxxas Component — As an official Traxxas part, these springs are engineered to the exact standards required for your RC vehicle and offer the reliability and quality you expect from the manufacturer.
Technical Performance
These Traxxas shock springs represent the pinnacle of suspension engineering for RC crawlers and trail vehicles. The 0.47 rate specification offers a lighter spring constant compared to higher-rate options, making it ideal for vehicles that are lighter in overall weight or for drivers who prefer a more compliant suspension setup that excels at maintaining tyre contact with uneven terrain. The progressive-rate winding means the spring starts soft to absorb small bumps and obstacles with minimal resistance, then progressively increases in stiffness as compression increases, effectively preventing bottoming-out during hard impacts. This dual-character performance is essential for serious RC crawler driving where you need both comfort and control. The long length specification is engineered specifically for the TRX-4 Long Arm Lift Kit, which extends the suspension travel and improves approach angles and departure angles for rock crawling and technical terrain. The natural finish coating provides excellent durability and corrosion resistance, ensuring these springs will maintain their performance characteristics through countless hours of challenging driving across the UK and beyond.

Frequently Asked Questions
- What is the spring rate and how does it affect my RC crawler's performance? — The 0.47 rate is a relatively soft spring constant that provides responsive control over small bumps and obstacles whilst maintaining enough stiffness to support larger impacts. A lower rate (softer spring) is ideal for lighter vehicles or for drivers seeking maximum tyre contact and ride comfort, whilst a higher rate would be better for heavier vehicles or those needing more suspension stiffness.
- Are these springs compatible with my TRX-4? — Yes, these springs are specifically designed for use with the TRX-4 Long Arm Lift Kit. They feature the long length specification required for this extended suspension system and will integrate perfectly with your TRX-4's suspension geometry.
- What does progressive-rate winding mean? — Progressive-rate springs are custom-wound so that they start with a softer rate (less resistance to compression) and gradually become stiffer as they compress further. This gives you the benefits of a compliant suspension for small bumps combined with the support of a stiffer spring for larger impacts.
- Can I use different spring rates to tune my suspension? — Absolutely. Traxxas offers GTS springs in different rates specifically to allow you to tune your suspension performance. Lower rates suit lighter vehicles or softer setups, whilst higher rates provide more stiffness for heavier vehicles or those requiring firmer suspension tuning.
- What is the natural finish coating? — The natural finish is a durable coating that provides excellent corrosion resistance without added weight, making these springs ideal for outdoor RC driving and maintaining long-term reliability in various weather conditions.
- Why would I need to replace my shock springs? — Shock springs can wear over time with use, or you may want to replace them to tune your suspension to different terrain types, vehicle weights, or driving styles. Having quality replacement springs ensures your TRX-4's suspension performs optimally.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm.
