About the Shock Springs


Tuning

Upgrading to different springs allows drivers to fine-tune suspension performance for track conditions and driving style. Stiffer springs improve stability, reduce chassis roll, and handle jumps with confidence, while softer springs increase traction and bump absorption on rough terrain. This tuning flexibility lets you dial in the perfect balance of control and responsiveness for maximum performance.

Features:

  • Allows fine-tuning of suspension setup
  • Improves handling and performance
  • Engineered for consistent performance
  • Agile springs give sharp handling
  • Mild springs give smooth control
  • Constant wire diameter for consistency
  • Small rate increments for fine tuning
  • Available in a variety of spring rates
