Your cart is empty.Hellwig's medium-duty EZ-990 Helper Springs pack a lot of capability in every box. Packaged complete with the same heavy duty powder coated and plated components, hardware and installation instructions as our heavy duty helper spring products, these kits are designed for the vehicles that need lighter assistance in carrying a load. Simple bolt on design using common hand tools provide the installer ease of installation and the vehicle owner hassle free use. Ideally suited for light towing and loads, these units are fully adjustable using the heavy duty U-bolts included in the kit using simple hand tools. If your tow and haul needs change, simply adjust the heavy duty U-bolts to suit the new load requirements. Once installed and adjusted you are free to haul or tow with greater control and stability. Manufactured with heat treated ASTM 5160 alloy spring steel in our California based facility, these units are rated up to 2,000 lb. level load carrying capacity. They are a great cost effective spring solution and can be adjusted independently for uneven side to side loads.

I liked the tech support. I installed on 1988 GMC. V1500 1/2 ton suburban 4 Wheel Drive. I had to replace the shocks because I had HD shocks with springs and the mounting bolts on the left side [ drive side] hit the shock.

Very simple to install. I bought this set mostly to take the sag out of my old half-ton springs. It easily took care of that, but hadn't had an opportunity to put a load on it until yesterday. I was intending to put 1000 lbs on it, and it ended up being 1850. My 06 Sierra 1500 sat just about as level as with no load. Very happy with the performance!

The helper springs look good and went on easily , not sure how they work yet since I haven't loaded truck up, but should do the job. The package came short a bunch of nuts,washers and bottom brackets that I had to make, after a trip to hardware I was able to complete the job in 3 hours, normally it would have been 1/2 hr. I had great product support and they did what they could to rectify -- very quick at responding to my concerns.

These fit well on my 2002 SilveradoThey seem to work OK although I haven’t put a lot of weight in the truck yetMy only complaint is that it should’ve come with Nylok nuts instead of jam nuts, and it is difficult to find nylocks because they used fine thread on everything

This product was guaranteed to fit my 1994 Chevy Suburban. It does not clear the body in front of the axle, the u bolts are too short, and it does not clear the rear a/c lines. After sending pictures and descriptions to Hellwig, they concluded that it will not fit and told me to return it to wherever I bought it. I was charged $40 to return a part that was guaranteed to fit. Still wondering why I had to literally pay for both Amazon and Hellwig's mistake. If you own a Chevy or GMC Suburban, Tahoe, Jimmy or other SUV, this will not fit your truck. Do not trust Amazon for parts unless you confirm that Prime will cover the return shipping.

Absolutely great product easy to install no need to replace your entire leaf spring set. Even the mechanic that works on my truck was impressed and said he will encourage others to use this instead of going through the costly repair of replacement of your leaf springs. Not only that customer service was excellent I made the mistake of ordering 2 thinking I needed 1 for each side and after explaining my mistake they are sending a return shipping label for the unused kit!!!!!if I could i would give them 6 stars.

Works flawlessly on 2003 F-150. Would suggest using power tools to install, as there is a substantial amount of thread to deal with during installation/adjustment. This decreased the rear end drop from the trailer tongue weight from 2" to 3/4" .

These were easy to install and seem like a high quality spring. I use my half ton truck to haul a lot of material and found the capacity was about 1500 lbs until the springs started to bottom out. Truck now rides very nice with the same weight and a bit rougher when empty. I would guess that it added about 750 pounds of carrying capacity, although you should never exceed the nameplate rating. I found that let me load it to full and still have plenty of suspension travel and a level riding truck that just seems much safer.

They are excellent quality springs, but seem to be a bit short.... they put all the stress of the load on the last 3" of the leaf spring and I have no doubt if loaded to much or ridden to hard the leaf would break. HOWEVER, on heavy leafs with a military roll, these would be the bomb. They work well on stock springs but be wary of where the load point is. I put a 3/4 strip of rubber under the shackle to spread the load out a bit. The shackle on a helper spring should rest right under the #2 leaf end, not on the #1 leaf 2-3" from the frame hanger; a bad place to put a load! For a stock set of leaf springs, they are a wee bit too long for a 3 leaf pack. Otherwise they are very well made and heavy duty and easy to install.

Works great on my suburban, solves the sagging spring issue that was prevalent for as long as chevy put SUVs on the chassis of trucks.Installation is fairly easy, ride is better, handling is better, easier towing and better capacityThe company is one of the best I have ever dealt with, my kit lacked the bolts and they overnighted a replacement set to me after a short and easy phone call.Needed a few extra long bolts because of my spring pack configuration, after an email to the company I had those within a few days, got these installed and couldn't be happier. Was worried about squeaking but have had no problem with that, all in all a great product from a great companyUpdate: 5 years later and still working great, I read some of the negative reviews and wonder what these people are doing...these are fully adjustable, so if you have the bolts only finger tight then you aren't getting much help, you can tighten the ubolts up and it will stiffen even more...these help a lot, but if you are trying to tow loads made for a 1 ton on a half ton these only go so far ... I added air struts to both my trucks and with 120-140psi plus these springs my ride is incredibly stiff
