Why Modern Coil Over System Design Matters

Factory suspension systems are designed to satisfy a wide range of driving conditions. This often results in compromises between comfort and performance. Enthusiast drivers frequently seek more precise control.

Progress CS Coil over systems allow suspension components to work together as a tuned package. Adjustable ride height and spring rates provide better balance and responsiveness. This improves both handling and driver confidence.

Our coil over designs offer consistency across varied conditions. From smooth highways to technical corners, Progress CS dampers maintain predictable behavior. This makes coil overs a necessary upgrade for performance-focused drivers.

Materials and Manufacturing Technology

Progress Tech Coil over systems are built using high-quality materials selected for durability and performance. Cold-wound springs maintain consistent rates under repeated stress. This ensures reliable suspension behavior.

Twin-tube dampers are tuned specifically for each application. This design balances control and comfort during daily driving. Cellular foam bump stops provide progressive load management.

Molded ispring isolators reduce noise and vibration. This allows performance gains without unwanted harshness. Precision manufacturing ensures consistent quality throughout the systems.

The Progress Tech Difference

Progress Tech develops Coil over systems using decades of suspension engineering experience. Every system is tested through extensive road miles and track use. This real-world validation ensures dependable performance.

Unlike generic suspension kits, Progress Tech coil over systems are application-specific. Components are selected and tuned to work together. This results in balanced handling and predictable performance.

Progress Tech products are designed to deliver long-term value. Each kit includes all required components for installation. Our focus remains on performance, reliability, and driver confidence.

Fitment, Standards, and Vehicle Compatibility

Proper fitment is essential for coil over system performance. Progress Tech designs each system for specific vehicle platforms. 

These systems are engineered as complete bolt-on solutions. They integrate with factory mounting points and suspension geometry. No permanent modifications are typically required.

Correct installation ensures optimal ride height and handling balance. 

Maintenance and Best Practices

  • Inspect dampers and springs periodically
  • Check mounting hardware for proper torque
  • Clean components to reduce debris buildup
