SUPER DUTY COIL SPRINGS   

heavy duty coil springs and front coil springsDayton Parts’ Heavy Duty Coil Springs are custom designed to give you 1000 lbs.* of additional load handling capability per pair with a maximum of ½ inch increase in ride height at zero additional load.  Dayton Parts’ Heavy Duty Coil Springs are the only practical helper spring alternative when shock absorbers are mounted inside the coil spring and are an excellent choice for vehicles equipped with diesel engines or snow plows. Heavy Duty Coil Springs also require no maintenance making them an excellent load handling solution for fleet vehicles, pickups, vans and motorhomes. Super Duty Coil Springs improve the handling and ride quality of heavily loaded vehicles, thereby reducing driver fatigue and increasing safety and efficiency.

We also carry standard duty coil springs for cars, trucks, and vans.  Please visit our coil spring application guide:
