• Genuine Traxxas OEM Component — These are original equipment manufacturer springs, ensuring perfect fitment and performance characteristics that match your vehicle's engineering specifications exactly.
• Pack of Two Springs — You receive two replacement springs in this pack, providing one complete rear suspension replacement or allowing you to keep spares on hand for quick swaps during tuning sessions or after damage.
• Red Colour — The vibrant red finish matches the aesthetic of many Traxxas models, particularly the Slash VXL-3S and Slash Extreme HD variants, maintaining the visual appeal of your RC car.
• Suspension Spares Category — As a suspension component, these springs are fundamental to your vehicle's handling dynamics and are among the most regularly replaced parts in RC maintenance.
• Wide Model Compatibility — These springs are compatible with multiple Traxxas Slash models including the 1:10 2WD RTR VXL-3S Brushless Short Course Truck in red, green and fox colours, as well as the Slash Extreme HD VXL variants, making them a versatile spare part.

Technical Performance

The Traxxas Springs, Rear (Red) (2.9 rate) represent the pinnacle of suspension tuning for 1/10 scale short course trucks. The 2.9 spring rate is carefully engineered to provide the optimal balance between ride compliance and chassis stability, allowing your brushless RC vehicle to maintain consistent handling through technical terrain and competitive racing scenarios. These springs work in conjunction with your vehicle's shock absorbers to manage suspension travel, control body roll during cornering, and maintain proper ride height under acceleration and braking. The genuine Traxxas manufacturing process ensures consistent material properties and dimensions across each spring, which is essential because even minor variations in spring rate can dramatically affect how your RC car UK handles. The red anodised finish not only looks striking but also provides corrosion resistance for durability in outdoor racing environments. When paired with a well-tuned shock absorber setup and proper anti-roll bar configuration, these rear springs will help your Slash 1/10 2WD RTR VXL-3S Brushless Short Course Truck or Slash Extreme HD VXL achieve predictable, responsive handling characteristics that competitive drivers demand.

Frequently Asked Questions

• What Traxxas models are these rear springs compatible with? — These TRX3757R springs are specifically engineered for the Traxxas Slash 1/10 2WD RTR VXL-3S Brushless Short Course Truck (available in red, green, and fox colour schemes) and the Traxxas Slash Extreme HD VXL 1/10 2WD RTR Brushless Electric Short Course Truck (available in red, green, and fox variants). If you own any of these short course truck models, these springs will fit perfectly and restore suspension performance to factory specifications.
• What does the 2.9 spring rate mean and how does it affect my RC truck? — The 2.9 rating indicates the spring constant, which determines how much force is required to compress the spring by a specific distance. A 2.9 rate spring is medium-stiffness, providing good balance between absorbing bumps and maintaining chassis control. If your truck feels too bouncy or unstable, a stiffer spring may help; if it feels too harsh, a softer spring could improve compliance. These springs are the factory standard for Slash models.
• How often should I replace my RC truck's rear springs? — Suspension springs typically last a long time, but you should inspect them regularly for visible cracks, bends, or loss of tension. Replace them immediately if damaged, or if you notice your truck's ride height dropping over time, which indicates spring fatigue. Even without visible damage, many competitive racers replace springs every season or after heavy use to maintain consistent performance.
• Can I use different spring rates for tuning my Slash? — Yes, experimenting with different spring rates is a common tuning technique. Stiffer springs (higher numbers) reduce body roll and improve stability in fast corners but can make the truck feel harsh. Softer springs (lower numbers) improve traction and ride compliance but may allow excessive body movement. The 2.9 rate is the factory recommendation, making it an excellent starting point for your setup.
• Are these genuine Traxxas parts? — Absolutely. These are OEM (original equipment manufacturer) springs produced by Traxxas to their exact specifications. Genuine Traxxas spares ensure perfect fitment, reliable performance, and compatibility with all aspects of your vehicle's suspension design. We stock only authentic Traxxas components.
• What tools do I need to replace these springs? — Replacing rear springs typically requires basic tools including a spring compressor (recommended but not always essential), screwdrivers, and possibly a hex driver set. Many RC enthusiasts use a simple spring compressor tool to safely remove and install the springs without damaging them or risking personal injury.
