Dayton Parts

Dayton Parts’ Heavy Duty Coil Springs (AKA Super 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. They 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. These HD/SD Coil Springs also require no maintenance making them an excellent load handling solution for fleet vehicles, pickups, vans and motorhomes. They improve the handling and ride quality of heavily loaded vehicles, thereby reducing driver fatigue and increasing safety and efficiency... which is also better for everyone you share the road with.
