The 1999-2016 Chevrolet Silverado 1500 SuperSprings are easy to installation and will go directly above the rear leaf springs. The super springs will work in conjunction with the existing suspension and engage when needed. With the increased spring rate you will get with SuperSprings, you will get an improved handling, towing capabilities and sway control.
Super Springs can be applied to many applications, including the ability to help the recreational and commercial user alike. We have customers that will use super springs on everything from campers and goose-necks, to fleets of contractors or municipalities with dump bodies. The easy installation will help with reducing repair cost.
