ST Muscle Car Springs Ford Mustang / Mercury Cougar all

These ST Sport Springs are made from chrome silicon steel, a strong material that resists sagging and block resistance, ensuring they maintain their shape over time. They're specifically tuned with vehicle-specific spring rates to work in harmony with your original shock absorbers, which is key for maintaining proper suspension function and a comfortable ride. By lowering your Mustang or Cougar, you'll reduce the vehicle's body roll, leading to more direct handling, improved steering response, and better stability when you're going around corners.

ST Suspensions constructs these springs to OEM quality standards, using a cold winding process for the chrome silicon steel before they are multi-tempered. A final epoxy coating is applied to help them stand up to different weather conditions. This attention to build quality means you get a long-lasting, quality driving experience that also improves the overall look of your classic muscle car.
