Heavy trailers or bed loads can make the rear end sag and steering feel sloppy. The Hellwig EZ-990 helper springs add up to 2,000 lbs of load-leveling support above your factory leaf springs to prevent squat and keep your truck level. By sharing the weight with your stock suspension, they help maintain steady braking, smoother handling, and correct headlight aim even with campers, boats, or tools in tow.
Hauling gear shouldn’t mean fighting body roll or bounce. These custom helper springs flex right along with your factory leafs to limit movement while keeping the ride stable. They work to reduce sway and body roll so the truck feels planted through corners and crosswinds, helping you stay steady and in control on highways or mountain grades.
Every haul is different, and this system adjusts to match. The included U-bolts can be tightened or loosened to fine-tune support for light or uneven loads, letting you balance each side independently. Whether you’re carrying tools on one side of the bed or towing a camper level, you can set the tension where it works best without over-stiffening the ride when empty.
Adding helper springs doesn’t need a shop visit. The EZ-990 bolts directly above your factory leaf springs using the included mounting hardware—no complex modifications required. With clear access points and simple hand-tool installation, you can upgrade your suspension in an afternoon and get back to towing or hauling with confidence.
The heavy-duty steel build and silver vein hammer tone powder coat finish stand up to rust and corrosion from road grime and weather. Once installed, the EZ-990 keeps performing season after season, extending the life of your factory suspension, tires, and brakes while delivering steady load support every time you hitch up or haul out.

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.
