Godspeed Project Inverted Shock Technology brings motorsport-level precision and durability to your vehicle. Unlike traditional upright shocks, our inverted struts place the thicker shaft at the bottom for added strength and rigidity. This reduces flex under aggressive driving, delivering sharper steering response and improved stability.

The inverted design also raises the oil chamber and seals away from dirt, debris, and road salt — protecting vital components and extending service life. A larger shock body improves heat dissipation, ensuring fade-free performance even during spirited street driving or track use.

With 20 levels of damping force adjustment, you can fine-tune rebound and compression to suit your driving style — from daily comfort to track-ready performance. Where applicable, the front struts include adjustable camber plates with pillow ball mounts, providing maximum alignment flexibility and a more precise steering feel.

Depending on vehicle application, not all four corners may feature inverted struts — some setups are front only, rear only, or full sets — each engineered for the best balance of performance, comfort, and reliability.

Key Benefits:

  • Godspeed Project inverted design for strength, rigidity, and sharper handling
  • 20-way adjustable damping for a personalized ride
  • Camber plates with pillow ball mounts (front, where applicable) for precise alignment & steering feedback
  • Protected seals and internals for longer service life
  • Superior heat dissipation for consistent performance
  • Application-specific design (front only, rear only, or full set)
