  • Firestone's most popular and comprehensive air helper spring line, Ride-Rite kits can be installed on most light trucks, motor-homes, RVs, SUVs and vans. Each application is specifically designed to maximize the vehicle's safe load-carrying capacity, stability, ride quality and brake effectiveness. Firestone Ride-Rite air helper springs provide load support through the use of air pressure that can be adjusted for changing loads. They enhance the ride by reducing inter-leaf friction. The system features individual inflation valves that allow for separate side-to-side or front-to-rear adjustment, which helps keep the vehicle level when carrying off-center loads and maintains ride quality under differing load conditions. Most Ride-Rite kits are no-drill systems, designed to use the vehicle's factory holes and mount between its frame and suspension. All the components are included in the kit for an easy installation that typically takes 1 to 2 hours. Kits come with a two-year limited warranty.

    • Against Manufacturer Defects to Original Purchaser
  • Forged Duck Head Torsion Bar Keys are like no other aftermarket torsion key front lift and leveling kit. Competitive products have simply mirrored the shape of the original key, and indexed or changed the position of the hex to put more initial preload on the torsion bar. We went through the painstaking process of redesigning the entire adjustment system, as well as the shape of the key itself. And, we are the only aftermarket torsion key manufacturer that includes a complete forged replacement drive system and bolts with every kit we sell. The result? A patented, forged system that not only allows front lift options up to 3.0 in. (varying by make and model), but all changes down to near OEM at the bottom of the adjustment. Duck Head torsion keys have the widest adjustment range of any key on the market, meaning that you have control over which adjustment option is right for you. We even include special shock extenders when a particular truck requires it so that the vehicle rides just like it did from the factory guaranteed.

  • Daystar Leveling Kits work within the factory suspension design, meaning that we work within the factorys design parameters to achieve an increase in ride height that levels the stance of the vehicle. Because we work within the factorys design, there are not a bunch additional modifications involved. Everything needed is included in the kit; theres everything you need and nothing you dont. If there are extra items required, such as longer shocks, its clearly stated in the application description. Torsion bar applications require their own unique approach to leveling the stance of the vehicle. With torsion bar applications, we supply new forged torsion keys that meet or exceed factory specifications. These torsion keys have been re-indexed to increase ride height up to 2in. and level the stance of the vehicle. In select applications, extended shock brackets are also included. Daystar Leveling Kits include only front lift components to level the stance of the vehicle. We also offer Budget Boost kits, which provide a mild increase in ride height and are more economically priced than our Leveling Kits. Since our start with Leveling Kits in 1995 weve used our expertise to develop over 300 applications that span all of the popular trucks and SUVs...do your homework and youll see that weve done ours!
