When you’re towing a small camper or hauling weekend gear, sagging in the rear can throw off your stance and steering. The Hellwig EZ-990 Helper Springs add up to 2,000 lbs of load leveling capacity above your factory leaf springs to keep things even. The truck stays level and stable under light loads, so handling and braking feel confident and balanced.
Uneven pavement or shifting cargo can make your ride bounce or sway. These custom helper springs flex with your leaf springs to limit that movement, reducing sway and body roll while keeping your ride steady. By taking some strain off your factory suspension, they also help extend the life of your springs, tires, and brakes.
Every load is different—sometimes it’s evenly balanced, sometimes not. The EZ-990’s U-bolts can be adjusted to suit different weights, and each side can be tuned independently. That means you can tighten one side up for uneven loads or back it off when things are lighter. It’s a simple way to fine-tune support without tools beyond what most folks already have.
You want helper springs that hold up over time. The Hellwig EZ-990 uses durable steel construction with a silver vein hammer tone powder coat finish that resists corrosion. The easy bolt-on design installs above your factory leaf springs using included mounting hardware and a step bracket style leaf that avoids contact with factory parts, giving you solid performance over years of towing and hauling.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Hellwig EZ-90 above axle helper spring set. These custom helper springs are going to bolt on above the factory leaf springs on your vehicle. They're gonna help reduce your sway and body roll, and prevent sagging when you're hauling heavy loads. This set is confirmed, designed specifically to fit your 2015 through 2023 Ford Transit T-150, and the T-250 cargo van. It's also going to work with the 2015 through 2023 Ford Transit T-350 cargo van, cutaway, and cab and chassis.
Now these springs will flex with the factory leaf springs to help limit your bouncing while providing optimal stability. The two springs here are going to have a weight capacity of 2000 pounds. Now when you hear that, it's very tempting to think that means it's going to increase your vehicle's weight carrying capacity by 2000 pounds, and that's not the case. There's no suspension enhancement system on the market that increases your vehicle's weight carrying capacity. So think of it less like a second set of hands that's helping lift more weight.
Think of it more like a back brace. So it's there to just kind of help take some of that strain off your factory suspension, help it to operate a little bit more efficiently, extend the life of your factory suspension, your tires, and your brakes. Now these are going to be very easy to get installed. It's just a bolt-on installation, so it will bolt on above the factory leaf springs. They do include instructions to walk you through that process to make sure that you have everything installed properly.
But one note is that you do not want to install these on vehicles with composite or plastic leaf springs, as these will be more durable, and could potentially damage your factory leaf springs if they are of that composite construction. Now when you're talking about suspension enhancement, most people, first thing that comes to their mind is airbags. So when you're comparing these to airbags, there are some benefits, some downsides. With your airbags, you do have to adjust the air pressure quite a bit. So if you have a heavier load, you'll add air in, give you that firmer engagement.
If you have a lighter load, you'll let air out, get you that lighter engagement. So there is a lot of maintenance involved in that. With this, you aren't gonna have that maintenance that you have to worry about, but you also aren't gonna have the same level of adjustability. So our U-bolts here can be tightened to give you a firmer engagement, but really, that's the only way to adjust these. They're more of a set it and forget it sort of option. You can adjust the springs individually from your driver's side and passenger side to give you support, if you have a really heavy toolbox, or something on the one side of your vehicle, you can get more support on that side. So they can be adjusted side to side, but there's gonna be fine tuning that can be done, but there's not that continuous adjustment available to you. So again, for some people, they might prefer the airbags to have that control over how much engagement they're gonna have. Other people, they're gonna prefer having that kind of set it and forget it, not have to worry about adding air pressure, taking air out, that sort of thing. So kind of just depends on what you're looking for. These are made here in the USA of a very durable steel construction. It's gonna ensure a nice long-lasting performance. If I zoom in here, you can see this does have a silver vein hammer tone powder coat finish. That's gonna help prevent corrosion. Make sure that these last a nice long time for you. They do come with a lifetime warranty. So if you we're to have any issues with them, you're more than welcome to reach out to us here at etrailer.com. But overall, I think this is just gonna be a great way to add a little bit more stability, some support for your factory suspension system. And that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

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

Do you have a question about this Vehicle Suspension?

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.
