The StableLoad® suspension enhancement dramatically improves vehicle handling characteristics by "pre-activating" the stabilizing effect designed for rear springs by keeping them actively under load the way your vehicle factory engineers designed them to operate. It’s also the only suspension enhancement that you can turn on and off with the lower leaf spring design so you can return to your factory ride when not towing or hauling.
Once you begin to tow or haul with your truck, pressure is applied on the factory overload springs of your vehicle’s suspension. The leaf springs on your vehicle are designed as a spring pack with upper and lower overload leaf springs. When the vehicle is loaded the spring pack engages. The problem is that there isn’t enough stability to support the load, resulting in poor handling characteristics. Here’s just a few you may have experienced:
Due to varying suspension options not all vehicle models come equipped with factory overloads.
Before ordering your StableLoad®, please first verify that your vehicle came equipped with factory overloads, and what type of overload (upper overload or lower overload) your vehicle is equipped with.
