$283.49 CAD

With our ST Sport Springs, you can equip your car with a spring kit that has been developed specifically for your vehicle and designed to fit your original shocks. Our ST Sport Springs are designed to work in conjunction with your factory dampers. Each set is matched to your particular vehicle to ensure your suspension continues to function properly. At ST suspensions, your driving experience is the main focus when it comes to our products. That is why we select vehicle specific spring rates in each ST Sport Spring kit to perfectly match your original dampers. Our ST Sport Springs are made out of chrome silicon steel to guarantee a long lasting and quality driving experience. You will not only benefit from a more direct handling but also improved steering and more stability during cornering because the vehicle's body roll is reduced. ST suspensions springs are constructed to OEM quality standards. They are made of high strength chrome silicon steel in a cold winding process then multi-tempered and have a final epoxy coating. This process helps resistance to different weather conditions. The high strength ST spring steel also ensures that our ST springs are block resistant and the springs do not sag.


ST sport springs are designed to work with the standard dampers to ensure the driving dynamics are improved. Depending on the lowering, ST sport springs have different spring rates that harmonize with the standard shock absorbers.
