The StableLoad® suspension enhancement manufactured out of stainless steel 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.
The lower quick-disconnect StableLoad® is now available in stainless steel! The new stainless steel StableLoad® are built for tough conditions. Our engineers developed these ultra high performance suspension enhancements to handle the toughest climates and terrain.

How does the stainless steel lower StableLoad® work? 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:
