Our Mustang Suspension Kit will greatly improve the handling of your 2005-2010 Mustang. This is a complete Mustang suspension package and includes springs, dampeners, jounce bumpers, and anti-roll bars. This suspension package was carefully designed to work as an integrated system for your vehicle to provide superior handling without sacrificing ride quality.This and every ROUSH suspension part is extensively engineered and tested by ROUSH's own performance engineers to deliver peak 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. 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.
