These Mustang Lowering Springs are intended to be used for lowering 2005-2014 Mustangs that already have the ROUSH® suspension system (whether production ROUSH Mustangs with ROUSH suspension or cars that have otherwise been outfitted with this system). In such cases, these suspension lowering springs will lower your vehicle approximately 1-inch.

This and every ROUSH® suspension part is extensively engineered and tested by ROUSH's own performance engineers to provide optimum performance for your vehicle. ROUSH suspension parts are developed over many hours on the race track, slalom, lane change, skid pad, and on a wide variety of different road surfaces to provide the best combination of ride and handling.

ROUSH engineers use the DIVAS Data Acquisition System, which is the same system used by Ford engineers, for collecting and analyzing vehicle dynamics. Rather than simply providing the best quality suspension parts available, ROUSH takes its development a step further by finely tuning its suspension offerings to the specific application as part of a whole system. The benefit of this approach is that ROUSH suspension parts work seamlessly with the other dynamic aspects of your car.

Since being established in 1976 as Jack Roush Performance Engineering, ROUSH has become the winningest name in racing, with numerous championships in professional drag racing, road racing, and NASCAR. The ROUSH company is also recognized internationally as a premier provider of automotive product development and systems integration solutions, with more than 2,000 employees in facilities across the globe. The company's success remains deeply rooted in the core values that are unique to ROUSH: reliance upon the talent of the individual, a disciplined work ethic, scrupulous attention to detail, and an acutely intense desire to be the best. As a result, every ROUSH product shares in this rich tradition of racing performance and the highest level of OEM quality and design.
