Greatly Enhances Stability and Control for Heavy Towing and Hauling
If you're towing and hauling with your F150 on a regular basis, you've probably noticed that sag, roll, and instability comes into play long before your truck hits its GVWR or GCWR. To help you win back control of your F150, Hellwig as developed with EZ-990 Rear Helper Spring Kit. Consisting of a heavy-duty spring that installs on top of your F150's factory leaf pack and adds 2,000lbs of load capacity while giving your F150 back control and stability when you're rolling around loaded. Hellwig's EZ-990 Helper Spring Kit greatly reduces sway, body roll, and instability caused by rear-end sag all in a low-cost package that's extremely easy to install.
High-Strength Leaf Springs with Stepped, Tunable Design
Hellwig's EZ-990 F150 Helper Spring Kit is made out of heavy-duty materials and was designed to drop right onto your F150's factory leaf packs without hassles. Each EZ-990 helper spring feature's a stepped design that allows you to adjust its load-bearing and ride by adding or subtracting the included U-bolts. The springs themselves are made out of high-strength 5160 alloy spring steel and come standard with a powder coat finish to protect against corrosion. Each spring easily installs onto your F150's factory leaf packs without the need for drilling, trimming, or other permanent modifications. Hellwig includes hardware and instructions, and backs their EZ-990s with a limited lifetime warranty.

These are great for reducing "squat" under load. They stiffen up the rear suspension slightly, but the ability to haul a whole yard of gravel with a half-ton pickup is well worth it. The installation isn't bad - about 90 minutes total - and the instructions are adequate. All in all, if you're looking to increase your ability to support a load, look no further. Stage 3 motorsports is great to work with, too!

Can you put Air Lift Ride Control air bags over the top of these? Looks like the arch might prevent that.
Asked by:
Matthew
- 2/21/2022
You would not be able to. Both the mount surface and the length of the Air Lift U-bolts are problems. In general, you really should only use one or the other. Either option should take you to the limits of your GVWR/GCWR. If you need help deciding, give us a call directly at 623-434-5277 or email us at

Is this compatible with a leveling block in the rear? I also have an add a leaf kit
Asked by:
Royce
- 12/1/2021
This kit will work fine with a larger rear block. However, your add-a-leaf kit may be an issue, since there's not a ton of thread on this kit's U-bolts that hold them to the leaf pack. The kit may work, but we can't 100% guarantee it.

Does the helper springs change the ride quality with no load in the bed?
Asked by:
Shawn
- 2/20/2020
You'll likely see a bit stiffer of a ride when unloaded. Unfortunately, we have not tried these springs ourselves as of yet, so we can't get a firm answer.
