Progress Technology Sport Springs

Sport lowering springs will significantly improve appearance and handling capability. Increased spring rates improve handling by lowering the center of gravity and reducing body roll, and the progressive spring rates help for a superior ride quality. These springs are designed to work with OEM shocks but will benefit from using high performance shocks such as Tokico, Bilstein, or Koni.

Our engineering staff has decades of experience in the design and tuning of performance suspension systems, including CART/Indy Cars, IMSA, SCCA, NASA, and SCORE competitors. These spring designs reflect our ability to develop a successful blend of appearance, handling capability, and ride quality.

Progress specifies only certified high-tensile SAE spring wire materials. Our springs are cold-wound on modern CNC coiling machines, then stress-relieved, pre-set and shot-peened for maximum durability.

These kits are covered under a Limited Lifetime Warranty (excluding finish). The owner must show proof of purchase for any warranty claim.
