A heavy trailer or bed load can make the back end sag and throw off your handling. 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. By reducing sway and body roll, they help your truck stay level and controlled when towing or hauling light loads. Steering and braking feel more confident because your suspension stays balanced instead of dipping under weight.
Not every load sits perfectly balanced. With the EZ-990 Helper Springs, you can adjust the U-bolts on the driver’s and passenger’s sides independently to handle uneven cargo. This lets you fine-tune support where it’s needed most, keeping the truck level even when tools, campers, or equipment weigh one side down. The springs flex with your factory leaf pack, so you get stability without a harsh ride.
Installing extra load support doesn’t have to be a big project. These helper springs mount above your factory leaf springs using a simple bolt-on design and include the necessary mounting hardware. There’s no need for complicated modifications—just solid parts that fit cleanly on top of your existing suspension so you can get back to hauling faster.
Work trucks and tow rigs see tough conditions, so lasting strength matters. The EZ-990 Helper Springs are made from durable steel and finished with a silver vein hammer-tone powder coat that resists corrosion. That means long-term performance you can count on even when the miles and weight start to add up.
By sharing the load with your factory springs, these helpers take strain off your original suspension, tires, and brakes. Less sagging and bottoming out means fewer worn components over time. The result is steadier handling today and a suspension system that keeps performing trip after trip.
Do not install on vehicles with composite (plastic) leaf springs.

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at these Hellwig EZ-990 Above Axle Helper Springs for small trucks. Now, this is a custom fit part. It is designed to fit the 1990 to 2012 Ford Ranger trucks, and also the 1994 to 2010 Mazda B Series trucks. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model of vehicle, and it'll show if this will work through application.
Now, these are custom helper springs. These will upgrade your factory these springs to reduce sway and body roll. These will prevent sagging when you're towing or hauling light loads, and they'll even help extend the life of your factory suspension, your tires, and your brakes. These do flex with your leaf brakes to limit any bouncing, while providing optimal stability. And these can be adjusted, just want to zoom in and show you.
On each end, they have these U-bolts right here, and you can see these U-bolts by how you tighten them. You can put so much tension on the spring. It can be adjusted to suit the different loads you're carrying. And what's nice is the drivers and the passenger sides can be adjusted independently for uneven loads. It is an easy install.
These will bolt above your factory lease springs. The mounting hardware's all included, comes even with a nice set of instructions. Now, these are a durable steel construction. They ensure long lasting performance, and also wanted to zoom in and show you the finish they put on these. It's a very, nice silver vein hammer toned powder coat finish.
helps resist corrosion, and gives it a good look. Now, these parts are made in the USA. Weight capacity is 2000 pounds. One note I do wanna mention is these Hellwig Helper Springs will not increase your vehicle's weight carrying capacity. But that should do it for the review on the Hellwig EZ-990 Above Axle Helper Springs for your small trucks.
Ratings & Reviews
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!!
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.
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.
It added lift to the truck and helps greatly when towing our 23 foot Travel Trailer.
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.
Product seems good, instructions are terrible . Can't find a video with my product for install anywhere .
Great product. Quick shipping. Would buy here again.
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.
U bolts are to long and would not allow the prop tightening.
Hellwig customer service advices to shim with washers.
Poor recommend repair.
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.
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.
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.
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.
