When you hitch up a trailer or load the bed with gear, the rear end can sag and throw off your steering and braking. The Hellwig EZ-990 helper springs add up to 2,000 lbs of load-leveling support above your factory leaf springs to keep things even. They cut down on sway and body roll while helping your truck stay level and stable when towing or hauling light loads.
Big bumps or uneven roads can make the rear bounce and sway when loaded. These helper springs flex with your leaf pack to limit that motion while still giving firm support. The result is a steadier ride that feels more controlled without losing the give that keeps it comfortable.
Loads aren’t always even side to side. The EZ-990’s U-bolts can be adjusted independently on each spring so you can dial in the right tension for each side. Whether you’re hauling tools on one corner or a camper that leans a bit, you can fine-tune stability and ride height to match.
You don’t need a lift or special tools to add real load support. These helper springs bolt above your factory leaf springs using the included step brackets and mounting hardware. The design avoids contact with factory parts for a clean fit, and the durable steel construction with silver vein hammer-tone powder coat finish resists corrosion for long-term performance.

Hi everybody. Andy here with etrailer.com. Let's take a look at these Hellwig EZ-990 helper springs. Now these helper springs are a custom fit for your 2009 to 2014 Ford F-150 two wheel and four wheel drives. Now on custom fit parts such as these springs, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle, and our fit guide will confirm if these will work for you, or if we have something comparable that will work for you.
Now these custom helper springs, with a load leveling capacity of 2000 pounds, are going to install above your truck's rear factory leaf springs to reduce sway and body roll while preventing sagging when towing or hauling light loads. And these are going to extend the life of your factory suspension, tires and brakes. These springs will flex with your leaf springs to limit bouncing while providing optimal stability. The U-bolts can be adjusted to suit different loads and the driver's and passenger side can be adjusted independently for uneven loads. Now these springs are made here in the USA of a durable steel construction, which is going to ensure a long-lasting performance.
And they feature a Silver Vein hammertone powder coat finish that's going to resist corrosion. Now this is a bolt-on insulation, and again, as I mentioned at the beginning of our time together, these are going to install above your factory leaf springs. Mounting hardware is included, and what I've tried to do here is assemble it loosely just to give you an idea of where the U-bolts and the hardware is gonna go when you install these. And I do wanna mention that you do not want to install these on vehicles with composite or plastic leaf springs. These helper springs are so durable and strong that they could potentially crack those composite or plastic leaf springs.
So if you have that, if you have those type of springs on your vehicles, these will not work for you. Now again, these do have a weight capacity of 2000 pounds. However, these Hellwig helper springs do not increase your vehicle's weight carrying capacity. Instructions are included to guide you through the insulation process, and Hellwig does put a lifetime warranty on this. Well, that's gonna wrap up our brief look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

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.

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.
