Overview
The Traxxas Spring, shock, White (GTR Long) (0.892 rate Blue) (1 pair) TRX7448 is a precision suspension component designed for RC enthusiasts looking to fine-tune their vehicle's handling characteristics. As a dedicated shock spring upgrade, this component allows you to customise your RC car's suspension response, ride height, and overall performance on the track or trail. Whether you're setting up a competitive race machine or simply optimising your casual basher for better handling, shock springs are essential tuning elements in any serious RC car UK collection.
Manufactured by Traxxas, a world-recognised leader in RC technology, these shock springs represent genuine OEM parts engineered to exacting standards. The GTR Long specification indicates these springs are designed for longer-stroke shock absorbers, providing extended suspension travel. This longer format is particularly valuable when you need to adjust your vehicle's geometry and compliance for different driving conditions, from smooth tarmac circuits to rough outdoor terrain. The white colour finish ensures you can easily identify these springs in your workshop, whilst the 0.892 rate specification provides a specific spring constant for precise tuning.
Available as a pair, this TRX7448 component pack gives you everything needed to replace or upgrade your existing suspension springs on compatible Traxxas models. Whether you're a seasoned competitor, a weekend basher, or just discovering the world of RC tuning for the first time, having the correct springs fitted is fundamental to achieving the handling balance your RC car UK deserves. These springs work in harmony with your shock absorbers to control body roll, maintain consistent ride height, and deliver responsive handling across varying track conditions.
Key Features
- GTR Long Format — These springs are designed with an extended length to accommodate longer-stroke shock absorbers, which means they provide greater suspension travel and allow for more sophisticated tuning options to match your driving style and terrain requirements.
- 0.892 Rate Specification — The spring rate of 0.892 defines the resistance to compression, which directly influences how your RC vehicle responds to bumps, maintains ride height, and handles cornering forces, making it essential to match the correct rate to your vehicle weight and driving conditions.
- White Colour Finish — The distinctive white colour makes these springs easily identifiable in your workshop and spares collection, reducing the risk of mixing up different spring rates during maintenance or tuning sessions.
- Genuine Traxxas Component — As an official Traxxas part, these springs are manufactured to the same exacting standards as the rest of your vehicle, ensuring perfect fitment, consistent performance, and long-term reliability that matches the quality of your RC machine.
- Sold as a Pair — This pack includes a complete set of two springs, allowing you to upgrade both sides of your suspension simultaneously for balanced and symmetrical handling characteristics.
- Precision Tuning Element — By selecting the correct spring rate, you can fine-tune your RC car's suspension to suit your specific driving technique, local track conditions, and vehicle weight, giving you a competitive advantage and improved enjoyment.
Technical Performance
The TRX7448 shock springs represent precision engineering at the heart of RC suspension tuning. The 0.892 spring rate is a critical specification that determines how the spring compresses under load and controls the vertical movement of your vehicle's chassis. In practical terms, spring rate directly impacts several performance characteristics: a stiffer spring resists compression more forcefully, which keeps the chassis higher and provides quicker response to steering inputs; a softer spring compresses more easily, allowing greater suspension travel and improved traction on rough surfaces by keeping the tyres in contact with the ground longer. The GTR Long format indicates these springs are engineered for shock absorbers with extended stroke length, typically found on modern Traxxas models designed for increased suspension compliance and travel. The white colour coating not only aids workshop organisation but also provides a protective finish that guards against corrosion and wear. Manufactured from high-quality spring steel, these components are engineered to withstand thousands of compression cycles without permanent deformation or loss of spring characteristics. The pair includes matched springs to ensure balanced suspension geometry across both sides of your vehicle, which is absolutely critical for predictable handling and consistent lap times in competitive RC racing or smooth, controlled performance in recreational bashing.

Frequently Asked Questions
- What vehicles are these shock springs compatible with? — The TRX7448 springs are designed for Traxxas models including the Rustler Ultimate VXL 4x4 1:10 Brushless in blue and green colour variants, and the Slash Ultimate 4x4 VXL 1:10 4WD Brushless Short Course Truck in orange. Always check your vehicle's manual or parts diagram to confirm compatibility before purchase, as fitting incorrect springs can negatively affect handling and performance.
- What does the 0.892 spring rate mean? — The spring rate, measured in kilograms per millimetre of compression, defines how much force is required to compress the spring by a given distance. A 0.892 rate is considered a relatively soft spring, making it suitable for vehicles requiring good suspension compliance and traction, particularly on uneven or bumpy terrain where maximum ground contact is beneficial.
- Why are GTR Long springs different from other spring formats? — GTR Long springs are designed to match longer-stroke shock absorbers that provide extended suspension travel. This format allows for greater vertical movement before the shock reaches full compression, which improves comfort, traction, and responsiveness across varied terrain compared to shorter-stroke alternatives.
- How often should I replace my shock springs? — Shock springs should be inspected regularly for signs of fatigue, discoloration, or permanent deformation. In competitive racing, springs are often replaced every season or after high-mileage use. In recreational bashing, replacement intervals depend on usage intensity, but examining springs every six to twelve months is recommended to maintain optimal suspension performance.
- Can I mix different spring rates on my RC car? — Mixing different spring rates front and rear is sometimes done intentionally for tuning purposes, but mixing springs of different rates on the same axle (left and right sides) will create unbalanced suspension geometry, leading to unpredictable handling, uneven tyre wear, and poor performance. Always use matched pairs of identical springs on the same axle.
- What is included with this purchase? — This product contains one pair of shock springs, meaning you receive two individual springs suitable for installation on both sides of your vehicle's suspension system. Additional components such as shock bodies, shock oil, or other suspension parts must be purchased separately if required.
