When towing or hauling light loads, rear-end sag can make the truck feel unstable and throw off your handling. The Hellwig EZ-990 helper springs add up to 2,000 lbs of extra load-leveling capacity above your factory leaf springs. By sharing the weight, they keep your ride level so steering and braking stay consistent even when the trailer or bed is loaded down.
Every load sits a little different, and these helper springs let you dial in the height you want. The U-bolts can be tightened to raise the suspension between 0 and 2 inches, letting you trim out sag or level side-to-side for uneven loads. Each side can be adjusted independently for better balance and control when one side of the truck carries more weight.
Rough roads and heavy loads can make a truck hop or sway. The EZ-990 flexes right along with the factory leaf pack to limit bouncing while keeping stability high. It helps control sway and body roll so the vehicle feels planted whether you’re pulling a camper, hauling gear, or cruising the highway.
These helper springs are made from strong steel with a silver vein hammer tone powder coat that resists corrosion. Mounting hardware is included, and the step bracket style leaf avoids contact with factory hardware for a clean, solid fit. It’s a straightforward bolt-on setup designed for dependable performance over years of towing and hauling.

Hi everybody, Andy here with etrailer.com. Let's take a look at these Hellwig EZ-990 Helper Springs. Now these are custom fit springs that are designed to fit your 2015 to 2020 Ford F-150 two-wheel and four-wheel drive. And on custom fit parts such as these, I do recommend using our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will let you know if these will work for you or if we have something comparable that will work for you. Now these custom helper springs have a load-leveling capacity of 2,000 pounds and they are going to install above your F-150's rear factory 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. And these springs will flex with your leaf springs to limit the bouncing while providing optimal stability. These u-bolts that you see here can be adjusted to suit different loads. The drivers and passenger sides can be adjusted independently for uneven loads. And 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 hammer tone powder coat finish that's going to resist corrosion. And the step bracket design of these leaf springs are going to avoid contact with your factory hardware. Now I do have these kind of set up offset just a little bit so you can get a clear view of the springs and the hardware here in the back as well. But obviously when you install these on your F-150, they are going to be level. Now this is a bolt-on installation, again, above your factory leaf springs.
Mounting hardware is included. And I do wanna make a special note that you don't want to install these springs on vehicles with a composite or a plastic leaf springs 'cause these are so durable that could damage those plastic or those composite leaf springs if you do have them. Instructions are included to walk you through the installation process, and again, these springs have a capacity, a load leveling capacity of 2,000 pounds. But just so you know, these springs are not designed to increase your vehicle's weight-carrying capacity. These are just going to help you get the maximum benefit from your suspension on your F-150.
These do have a lifetime warranty from Hellwig and that's going to wrap up our 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.
