Heavy trailers and packed beds can make the rear end sag and steering feel light. These Hellwig Load Pro 25 Progressive Helper Springs add 2,500 lbs of load-leveling capacity above your factory leaf springs to keep things level and controlled when towing or hauling. By reducing squat, they help keep your handling predictable and your braking smooth even with weight pushing down on the rear.
A stiff ride when unloaded isn’t fun, and these helper springs are designed to avoid that. The progressive rate springs flex with your factory leaf pack so they only engage as load increases. That means no harsh ride when empty, just the extra support when you need it most. They also limit bounce while keeping the truck stable over dips or uneven pavement.
Not every load is the same, and sometimes one side sits lower than the other. The included U-bolts on these Hellwig springs can be adjusted independently for each side, letting you fine-tune support to match uneven cargo or trailer weight. You get a level stance and consistent handling no matter how you pack the bed.
These helper springs are made from heavy-duty steel and finished with a silver vein hammer tone powder coat that resists corrosion. The custom bolt-on installation kit mounts above your factory leaf springs for a solid connection that’s easy to install and built to handle years of hauling without giving up performance.
If your vehicle is equipped with a factory contact overload it may need to be removed before installing the new helper springs. Please consult the installation guide. Do not install on vehicles with composite (plastic) leaf springs.

easy install
everything fit perfect
thank you
So far so good! purchased these for my old supercrew to locally haul my 16'trailer dbl axle utility trailer loaded with my 3540 W/cab/loader/box blade. Most of the machine weight (maybe 6K) is centered over the trailer axles, but these helper springs do a lot for keeping the sag up and balanced.
