With a 0.623 spring rate and distinctive orange colour coding for easy identification in your spares box, this genuine Traxxas component ensures your suspension tuning remains consistent and repeatable across multiple vehicles or different racing conditions.
RC Model Shop stocks authentic Traxxas spare parts and tuning options for every level of RC enthusiast. Whether you're upgrading a ready to run RC truck or fine-tuning a competition-grade racing platform, genuine OEM components like these shock springs are fundamental to achieving the performance characteristics you've invested in. Available in convenient 1-pair packs, this TRX7440 unit ensures you have the correct spring rate needed to dial in your suspension geometry and achieve optimal handling balance on track or off-road.
Key Features
- Genuine Traxxas OEM Component — This is an authentic manufacturer-approved spare part, ensuring compatibility and performance reliability with your Traxxas vehicles. Genuine parts eliminate the risk of fitment issues or performance inconsistencies that can occur with aftermarket alternatives.
- GTR Long Configuration — The extended length design of these shock springs provides increased suspension travel, allowing your vehicle to absorb impacts more effectively and maintain traction during aggressive driving or jumping. This extended format is specifically optimised for modern Traxxas 4WD vehicle architectures.
- 0.623 Spring Rate (Orange) — The spring rate specification determines how much resistance the spring provides when compressed. This mid-range rate offers a balanced setup suitable for mixed terrain driving, making it an excellent all-purpose tuning choice for RC car enthusiasts who enjoy both on-road and off-road running.
- Colour-Coded Orange Identification — The bright orange colour makes these springs instantly identifiable in your spares collection, preventing confusion when swapping suspension components and ensuring you use the correct spring rate for your intended setup.
- 1-Pair Pack Format — Supplied as a matched pair, these shock springs are pre-selected for consistent performance. Having multiple springs allows you to experiment with different setups or maintain backups for competitive racing environments.
- White Construction — The white finish provides excellent visibility of the spring assembly during installation and adjustment, and helps distinguish these springs from other rates in your toolbox.
- Suspension Tuning Essential — Shock springs are fundamental to suspension geometry and handling balance. Being able to swap spring rates allows you to adapt your vehicle's performance to different tracks, weather conditions, and driving styles without requiring major mechanical modifications.
Technical Performance
The Traxxas TRX7440 shock spring represents precision engineering optimised specifically for Traxxas's advanced 4WD suspension systems. The 0.623 spring rate places these springs in the medium compliance range, making them suitable for drivers who want predictable handling without excessive stiffness that can reduce traction in rough conditions. The GTR Long configuration provides extended suspension articulation, which is particularly beneficial when running brushless RC cars at high speeds or navigating technical off-road courses. Spring rate is measured in pounds per inch (lbs/in), and the 0.623 specification indicates that approximately 0.623 pounds of force are required to compress the spring by one inch. This metric allows you to make precise tuning adjustments: softer springs (lower rates) provide smoother ride quality and better traction in bumpy terrain, whilst stiffer springs (higher rates) maintain ride height under cornering loads and improve stability on smooth surfaces. The white colour and orange rate designation ensure you can quickly identify these springs in your collection. These genuine OEM springs are manufactured to Traxxas's exacting tolerances, guaranteeing consistent performance across multiple pairs and eliminating the performance variability that can occur with non-OEM alternatives. The GTR Long design integrates seamlessly with Traxxas's shocks and damper assemblies, ensuring that your suspension geometry remains correct and your vehicle handles predictably across different driving conditions. Whether you're preparing your RC vehicle for track racing, bashful weekend driving, or competitive events, having the correct spring rates available allows you to optimise your setup for maximum performance.

Frequently Asked Questions
- What is a shock spring rate and why does it matter for RC cars? — The spring rate indicates how much force is needed to compress the spring by a fixed distance, typically measured in pounds per inch. In RC vehicles, the spring rate directly affects how your vehicle sits on its suspension, how it responds to bumps and jumps, and how much weight transfer occurs during cornering. Softer springs (lower rates) provide better traction and a smoother ride over rough terrain, whilst stiffer springs maintain ride height during aggressive cornering and prevent bottoming out during big jumps. The 0.623 rate of these TRX7440 springs offers a balanced middle ground suitable for most driving conditions.
- How do I know which spring rate to use for my RC vehicle? — Spring rate selection depends on your driving style, track surface, and vehicle weight. Generally, start with the manufacturer's recommended rate (often marked on your vehicle's original springs) and adjust from there. Softer springs improve traction on bumpy surfaces, whilst stiffer springs improve stability on smooth tracks. These orange-coded 0.623-rate springs are a popular choice for balanced all-around performance on Traxxas 4WD vehicles like the Rustler Ultimate and Slash Ultimate models.
- Are these springs compatible with all Traxxas models? — No, these GTR Long springs are specifically designed for certain Traxxas 4WD models including the Rustler Ultimate VXL and Slash Ultimate 4x4 VXL. Always verify compatibility with your specific vehicle model before ordering. The GTR Long configuration indicates the extended length design, which may not be compatible with vehicles using standard-length shock mounts.
- What makes Traxxas OEM parts better than aftermarket alternatives? — Genuine Traxxas components are engineered and tested specifically for your vehicle, ensuring perfect fitment and performance reliability. OEM parts are manufactured to consistent tolerances, eliminating variability in spring rates that can affect handling predictability. Whilst aftermarket springs may be cheaper, genuine Traxxas parts guarantee compatibility and performance characteristics that match your vehicle's suspension geometry.
- Can I mix different spring rates on the same vehicle? — Technically you can, but this is advanced tuning that should only be done by experienced RC racers who understand suspension geometry. Most users purchase matched pairs with identical rates to ensure consistent handling front and rear. Mixing rates can create unpredictable handling characteristics and is not recommended for general driving.
- How often should I replace my shock springs? — Springs don't wear out like dampers do, but they can lose their temper (stiffness) over time with constant use, especially in high-heat environments. If you notice your vehicle's ride height slowly dropping or handling becoming unpredictable, fresh springs may restore performance. It's good practice to keep spare springs on hand for competitive racing so you can maintain consistent setups.
- What does the orange colour coding mean? — Traxxas uses colour codes to identify different spring rates at a glance, making it easy to find the correct springs when swapping setups. Orange indicates a specific spring rate (in this case, 0.623 lbs/in). Having colour-coded springs prevents confusion when managing multiple vehicles or frequently changing your tuning configuration.
