Heavy trailers or bed cargo can make the rear of your truck sag, throwing off handling and braking. Hellwig EZ-990 helper springs add up to 2,000 lbs of load-leveling support above your factory leaf springs to keep things level and stable. With the extra support in place, your suspension carries weight evenly without bottoming out or squatting under load.
A stiff rear end makes rough roads even worse when you’re towing or hauling. These helper springs flex with your factory leaf springs to control bounce and sway while keeping the ride composed. The result is better stability and less body roll when cornering, braking, or hitting uneven pavement.
Not every haul weighs the same. The EZ-990’s U-bolts can be adjusted to suit different loads, and each side can be set independently to balance uneven weight. Whether you’re carrying a heavy toolbox on one side or a camper that shifts weight rearward, you can dial in the right support for a level ride every time.
Installing load support shouldn’t require a shop visit. The EZ-990 helper springs bolt directly above your existing leaf springs with mounting hardware included. No special tools or air lines—just a straightforward setup you can tackle in the driveway with basic hand tools.
These helper springs are made from strong steel with a silver vein hammer tone powder coat finish that resists corrosion. That combination means solid performance year after year with no sagging or rust issues getting in the way of reliable towing and hauling support.

I bought another pick up, so I took these off my old one and installed on my newer truck, still works absolutely great. Highly recommend.

They work great. Truck is still at the proper height with the extra weight. There has been no loosening or adjustments needed.

Glad to hear they are helping, Thomas! Looks like you have a pretty good amount of weight back there as well, so that's quite the compliment! ^___^ What kind of bike is that? Couldn't tell from the picture.
