Progress Technology Sport Lowering Springs will significantly improve appearance along with increased spring rates for upgraded handling capability, and progressive spring rates for superior ride quality. Sport Lowering Springs are now available in our charcoal gray powder coating and always offered with our Limited Lifetime Warranty.

Progress Lowering Springs are designed to reflect the ability to develop a successful blend of appearance, handling capability, and ride quality. These Sport springs feature increased spring rates for upgraded handling capabilities as well as progressively wound springs for superior ride quality. These Sport springs are designed to work with OEM shocks but will benefit from using high performance shocks. Progress specifies only certified high-tensile SAE spring wire materials. Progress Sport Springs are cold-wound on modern CNC coiling machines, then stress relieved, pre-set, and shot-peened for maximum durability.

Established in 1995, The PROGRESS Group Inc. has evolved from modest beginnings as a distributor of suspension components to the manufacturer of the nationally recognized PROGRESS Technology line of performance handling components.

After ten years of continuous development, The PROGRESS line of suspension components has become a premier program for tuning today's popular automobiles. Our long-term commitment to superior products and unparalleled customer satsfaction are fundamental to our business today.

PROGRESS creates and calibrates the dyno curves in all the coil-overs we design from our in-house shock dyno, and matches the spring rates on our load cell to optimize performance and ride compliance. All sport springs are painstakingly designed in-house and extensively tested to meet our exacting standards.
