When you’re towing a trailer or hauling tools and gear, the rear end can sag and throw off balance. The Hellwig EZ-990 Helper Springs add up to 2,000 lbs of load leveling capacity above your factory leaf springs to stop that squat before it starts. They upgrade your suspension so your rig stays level, steering feels steady, and braking stays consistent even when the bed is full or a trailer is hitched up.

Heavy loads can make a truck sway or roll more through corners. These custom helper springs work with your factory leaf springs to reduce body roll and sway so the truck feels more planted on the road. You can adjust the U-bolts to tune the spring tension for different loads, keeping handling stable whether you’re heading down a mountain grade or pulling into a campsite.
Uneven cargo doesn’t have to mean a crooked ride. Each side of the EZ-990s can be adjusted separately so you can dial in support for an off-center camper or tools stacked on one side of the bed. The springs flex with your leaf packs to smooth out bounce while keeping everything balanced and level.
These helper springs are made from durable steel with a silver vein hammer tone powder coat finish that resists corrosion. The easy bolt-on design mounts directly above your factory leaf springs using the included hardware, so you get long-lasting performance without complicated setup. It’s a simple, strong way to extend the life of your factory suspension, tires, and brakes while keeping your truck stable when it’s working hard.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at these Hellwig EZ-990 Above Axle Helper Springs. These are custom helper springs that will install above the factory leaf springs on your vehicle. They're gonna help to reduce your sway and body roll and prevent sagging when you're towing or hauling loads. These are designed specifically to fit your 2014 and newer Toyota Tacoma. So it is gonna be a very simple installation being that it's designed specifically for your Tacoma.
These springs will flex with your factory leaf springs to help limit bouncing while providing optimal stability. These will 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. There's no helper suspension system on the market that's gonna increase your vehicle's weight carrying capacity. 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 your factory suspension take some of that strain off of it, help to extend the life of your factory suspension, your tires, and your brakes. Like I said, these are gonna be very easy to get installed. It's just gonna bolt above your factory leaf springs. All the mounting hardware that you're gonna need is included.
It is important to note that you should not install these on vehicles with composite or plastic leaf springs as these durable metal springs could potentially damage the plastic springs. So when you talk about suspension enhancement most people are familiar with airbags. That's what seems to be the most popular. So if you're comparing these to airbags, airbags are gonna give you more adjustability. So if you're hauling a really heavy load, you can add air to it, give you more support.
If you unload, you've got an empty bed or very light load, you can let air out airbags and just have a a light support. These are gonna be more of a set it and forget it kind of set up. You can adjust the U-bolts to accommodate, to alter a little bit, but not nearly as much as you would get with the airbag set up. But the benefit of these is that you don't have to adjust them. So if you are the kind of person that doesn't wanna have to worry about how much pressure is in your bags, you just wanna be able to get your stuff loaded up, these are gonna be a great way to go. So like, again, a little bit less adjustability but you can adjust the driver's side and passenger side independently. So if you have an uneven load, a really heavy toolbox on one side of your Tacoma or if, you know, if you're needing to give that extra support on one side if you can't adjust one and not the other.=, so it's gonna give you more even balance overall. So very beneficial here, even though you don't get as much adjustability as you would with airbags. These are made here in the USA of a very durable steel construction, so that's gonna ensure a nice long lasting performance. These do have a silver vein hammer tone, powder coat finish. That's gonna prevent corrosion, make sure that these are lasting you a nice long time. They do come with a limited 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 always like working with our customers to make sure you're getting good quality products and finding the right solution for your problems. But I really don't think you're gonna have any issues with these. I think they're gonna do a good job for you. Again, very simple to get installed and give you that low maintenance support that you're really looking for. So 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.

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.

I am sorry to hear about the U-bolts. Are they wearing quicker than normal? Or not tightening or sitting correctly?
