When you hitch up a trailer or haul a bed full of gear, the rear end shouldn’t sag. The Hellwig EZ-990 Helper Springs add up to 2,000 lbs of load leveling capacity above your factory leaf springs to prevent squat and keep your truck level. Staying level means steadier braking, more predictable steering, and headlight aim that stays where it should, even when the back is packed with weight.
Heavy loads can make your truck lean through turns or bounce over dips. These custom helper springs flex with your existing leaf springs to limit body roll and sway while keeping the ride stable. Each side can be adjusted independently to balance uneven cargo, so whether one side is heavier or not, you stay smooth and controlled on the road.
You don’t need a lift or fancy tools to get real suspension help. The EZ-990’s bolt-on design mounts above your factory leaf springs using included hardware and step-bracket style leaves that clear factory components. It’s a straightforward install that fits right into a DIY setup, letting you fine-tune support with simple U-bolt adjustments for different loads.
A helper spring only works if it lasts through years of towing and hauling. The Hellwig EZ-990 is made from durable steel with a silver vein hammer tone powder coat finish that resists corrosion and keeps it looking good after long miles in tough conditions. That strength helps extend the life of your factory suspension, tires, and brakes by sharing the load every time you hook up or haul heavy gear.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Hellwig EZ-990 above-axle helper spring set. These are custom helper springs that will bolt on above your factory leaf springs on your vehicle. They're gonna help to reduce your sway and body roll, as well as prevent sagging when you're towing or hauling your heavy loads. Now, these are designed specifically to fit your 2002 through 2008 Dodge Ram 1500. So because these are designed specifically for your RAM, it is gonna be a very simple install.
It's just gonna bolt above your factory leaf springs. All the mounting hardware is included. They also include instructions to walk you through that installation process, make sure that everything's installed properly for you. One thing to note is you do not want to install these on vehicles that have composite or plastic leaf springs as these are gonna be more durable than your composite springs so it could potentially cause damage. But these springs will flex with the factory leaf springs to help limit bouncing while also providing optimal stability.
They are going to have a weight capacity of 2,000 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 2,000 pounds. And that's not the case. It's not going to increase your weight-carrying capacity. It's really just there to help support your factory suspension system.
So think of it less like a second set of hands that's helping you lift more weight. Think of it more like a back brace. So it's there to help take some of that strain off your factory suspension, help to extend the life of your factory suspension, of your tires and your brakes, those sort of things. When you compare these to say airbags which seems to be what most people are most familiar with when you talk about suspension enhancement, airbags do a great job of giving you a lot of control. So you can add air if you need a little bit more support or you can let air out if you've got a lighter load and you need less engagement.
These aren't gonna give you a whole lot of adjustability. You can tighten down the U-bolts on the side here and that will allow you a little bit of adjustability. But really, if you are looking to have more control, I would recommend airbags for you. If you're looking for more of just a kind of install it, set it and forget it sort of set up, I think this is gonna be a better way to go for you. So you don't have to worry about how much air pressure you have in your bags, leaks and that sort of thing. And these are made here in the USA of a very durable steel construction, so they are gonna have a nice long lasting performance for you. This does have a silver vein hammer tone powder coat finish that's gonna help prevent corrosion. So again, make sure that you get a nice long lasting performance. I do wanna point out that I have these offset just so you can see this back spring better. When you actually get them installed, they will be at the same point so they're not gonna be installed offset, but I just wanted to point that out for you. These 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. We're always happy to work with our customers, make sure you're getting good quality products and having a good experience. So overall, if you're wanting to help to improve your RAM's suspension system, this is gonna be a great way to go. And that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

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.
