Heavy trailers or bed loads can make the rear end sag and throw off handling. The Hellwig EZ-990 Helper Springs add up to 2,000 lbs of load-leveling capacity to keep your vehicle level when towing or hauling light loads. By upgrading your factory leaf springs, they help maintain a steady stance so your steering, braking, and headlight aim stay right where they should.
Every bump, curve, and crosswind puts stress on your suspension. These helper springs flex with your factory leaf springs to reduce sway and body roll while limiting bounce. The result is better ride stability and control whether you’re pulling a small trailer or carrying uneven cargo in the bed.
Loads aren’t always the same from one trip to the next. With adjustable U-bolts, you can fine-tune spring tension to match what you’re hauling. Each side can be set independently to handle uneven loads, keeping your truck balanced and confident even when gear is off center.
You don’t need a shop full of tools to get these helper springs in place. The EZ-990s use an easy bolt-on design that mounts above your factory leaf springs without interfering with existing hardware. Step-bracket style leaves clear factory components for a clean fit, and all required mounting hardware is included for straightforward installation.
From daily hauls to weekend trips, these springs are made to last. Heavy-duty steel construction paired with a silver vein hammer tone powder coat finish resists corrosion and keeps performance consistent over time. Hellwig backs it all with a lifetime warranty for lasting peace of mind.

Hi everybody, Andy here with etrailer.com. Let's take a look at these Hellwig Ez-990 Helper Springs. Now these helper springs are going to fit numerous different types of vehicles so please take 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 let you know if these will work for you or if we have something comparable that will work for you. These custom helper springs with a load leveling capacity of 2000 pounds are going to upgrade your factory leaf springs installing above your vehicle's rear factory leaf springs to reduce sway and body roll while preventing sagging when towing or hauling different loads, they're going to extend the life of your factory suspension, tires, and brakes and these springs will flex with your leaf springs to limit bouncing while providing optimal stability. Now these U-bolts can be adjusted to suit different loads.
The driver's and passenger's 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 long lasting performance. And they feature a silver vein hammer tone powder coat finish, that's going to help resist corrosion. And this is again, a bolt-on installation above your vehicle's rear factory leaf springs. The step bracket style leaf avoids contact with factory hardware and the mounting hardware is included.
And as you can see, I have assembled the U-bolts and the hardware just to kind of give you an idea of where the hardware's gonna go on the springs when you are installing these. Instructions are included to walk you through the installation process. And again, these do have a weight capacity of 2000 pounds. However, be aware that these helper springs will not actually increase your vehicle's weight carrying capacity. And also, one final note I wanna make.
These are not going to be compatible with vehicles that have composite or plastic leaf springs. Because of the durability and the robust nature of these springs, they could potentially crack or damage your composite or plastic leaf springs. So again, if your vehicle does have composite or plastic leaf springs, these helper springs are not going to be compatible. So Hellwig does put a lifetime warranty on these springs. And that's gonna wrap up our look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Worked Great! Exactly what our customer needed.
Some of the nuts were difficult to start onto the u-bolts, tried to strip the threads
Well they work great. I currently have 4 of second round of nuts that are supposed to be installed. Not catching. Which is frustrating cause I hand started all but can’t get 2 round of nuts on.
This is exactly what we needed to finish our customer's job. This shipping was so quick. Thank you all so much!!
Completely helped the squating rear on 350xl transit box truck with dual rear wheels. Improved ride and handling when loaded. Rides smooth and looks like it is supposed to.
These work great. Very easy install. I have a bed slide and a camper top, and these brought the rear back up to the proper height.
Great product. Quick shipping. Would buy here again.
Product seems good, instructions are terrible . Can't find a video with my product for install anywhere .
Easy to install, very effective and didn’t have much effect on ride quality. Mine worked on the lowest setting with a 16’ camper.
These springs eliminated the rear sag from adding a shell, rubber bed mat, and a little gear.
Easy to install as well, but recomend having a 7/16X20 tap/die to clean threads on supplied u-bolts.
Easy to install. It should help stabilize the rear springs when I tow our boat.
The product fit well and installed would have been a breeze if it wasn’t for the hardware. The u bolts are very poor quality with burrs and poorly tolerances threads. In addition only half the hardware was the correct size. One set of nuts was too big for the u bolts. The hardware was also low quality. In my opinion it should have all been grade 8 corrosion resistant hardware and it is much lower grade. I ended up having to buy all new hardware to be able to install at an additional cost. Now that it is installed the product works fantastic. Just be aware you may need to purchase extra hardware to get it installed.
Helper springs made my Ram 1500 Conversion Van have a more comfortable ride. The springs raised the profile of the back of the van by about 1-1/2", which is not noticeable and the van still looks good. My RV Travel trailer lowered the back half of the van by about 1", before I installed the helper springs. The helper springs should enhance the ride of the van.
The springs lifted my Tacoma with a cap about an inch higher. It would have been more helpful if the directions indicated that a C-Clamp would be useful to compress the spring ends to allow the u-bolts to be installed. The directions also indicated the long end of the spring should face forward. I measured the spring from the end to the hole and this was the same either way, so was confusing. I purchased longer axle u-bolts since the added thickness of this extra spring made the factory u-bolts too short IMO. I feel that should have been part of this kit. Lastly, the u-bolt on the driver's side did not need to be installed sideways per the instruction. It fit fine just as the other u-boults were installed. Maybe the instructions could be updated to be more accurate.
U bolts are to long and would not allow the prop tightening.
Hellwig customer service advices to shim with washers.
Poor recommend repair.
Easy install great fit. Readjusted for our new trailer in 10 minutes and working wonderfully.Leveled the truck and rides smooth..
I was a great addition to my RST 1500 Chevy and I transferred to my High Country 1500 Chevy and never missed a beat towing the travel trailer.
Easy to install, does not affect the ride much , worked great pulling my fish house to the lake. I showed my helper springs to one of my customers, gave him the part number for his truck and he ordered them from e-trailer today. Great product.
It worked perfectly for my needs. It helped my 2011 Silverado from sagging too much without raising the backend of the truck much (1/4 to 1/2) while empty. I can adjust this added spring to have less sag but then I raise the backend a little more. It's at a happy medium. It is easy to fine tune it if I want more or less spring support.
Loaded my tacoma with a portaboat on the ladder rack and a few hundred pounds of camping gear. The sag was gone after installing these. The ride is a little bit stiffer when empty as to be expected but not bad even on washboard dirt roads. These can be fairly easily installed and removed if desired. Hardest part is jacking up the truck to sit on the frame
Way better than expected. Huge difference in the rear suspension. It’s almost like having a sway bar.
Well made kit, easy to assemble, easy to follow instructions. Had a problem with the nuts (wrong size) but Helwig handled it promptly and courteously.
Parts ordered, shipping box was compromised, missing parts to do the install.
Now i need to fab a square u-bolt to use the product like i planed this weekend.
Ez-990 helper springs sagged with 800lb camper and bottomed while driving over speed bumps unless creeping. Unloaded there was noticeable tightness, almost binding feeling on bumps. I removed and checking options like airbags or Sumo.
