Heavy trailers or bed loads can make the rear end sag and steering feel sloppy. The Hellwig EZ-990 helper springs add up to 2,000 lbs of load-leveling support above your factory leaf springs to prevent squat and keep your truck level. By sharing the weight with your stock suspension, they help maintain steady braking, smoother handling, and correct headlight aim even with campers, boats, or tools in tow.
Hauling gear shouldn’t mean fighting body roll or bounce. These custom helper springs flex right along with your factory leafs to limit movement while keeping the ride stable. They work to reduce sway and body roll so the truck feels planted through corners and crosswinds, helping you stay steady and in control on highways or mountain grades.
Every haul is different, and this system adjusts to match. The included U-bolts can be tightened or loosened to fine-tune support for light or uneven loads, letting you balance each side independently. Whether you’re carrying tools on one side of the bed or towing a camper level, you can set the tension where it works best without over-stiffening the ride when empty.
Adding helper springs doesn’t need a shop visit. The EZ-990 bolts directly above your factory leaf springs using the included mounting hardware—no complex modifications required. With clear access points and simple hand-tool installation, you can upgrade your suspension in an afternoon and get back to towing or hauling with confidence.
The heavy-duty steel build and silver vein hammer tone powder coat finish stand up to rust and corrosion from road grime and weather. Once installed, the EZ-990 keeps performing season after season, extending the life of your factory suspension, tires, and brakes while delivering steady load support every time you hitch up or haul out.

Ratings & Reviews
They were very easy to install and I like the added stiffness it gave to my suspension. I have yet to hook up to my camper but I am looking forward to it.
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.
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.
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.
Easy to install and works great so far.
