When a trailer or bed load pushes your rear suspension down, the Hellwig Load Pro 35 helper springs deliver 3,500 lbs of extra support. They bolt above your factory leaf springs to prevent sagging when towing or hauling heavy loads. With the added support, your truck stays level so steering, braking, and headlight aim stay consistent under stress.
Weight shifts or uneven roads can make a loaded vehicle sway or bounce. These heavy-duty helper springs flex with your factory leaf springs to limit body roll while providing optimal stability. The result is a smoother ride that feels more controlled through corners, highway dips, and uneven terrain.
Sometimes one side of the load is heavier than the other. The Load Pro 35 lets you adjust the driver’s and passenger’s sides independently to balance uneven loads. You can fine-tune tension on each spring so your truck rides level no matter how cargo weight is distributed.
The durable steel design and silver vein hammer tone powder coat finish resist corrosion and hold up through constant use. The bolt-on installation kit is included for a straightforward setup above your existing leaf springs. Once installed, you’ve got reliable load support that extends the life of your suspension, tires, and brakes without changing your truck’s weight-carrying capacity.

Ratings & Reviews
Great Product
RV was soft in the rear. These where not so bad to install. And make a big differance in stance abd ride. I think they are a must have.
GREAT CUSTOMER SERVICE
Great service,people are great to work with, they back every they sell.
I've used E-Trailer for years
The product is great and installed fairly easy. The only issue I had was the box was not secure upon arrival and we had to make two plates that were missing. The box needs to be heavier.
Customer service person Jill is a diamond in the rough, a consummate professional diservant of a pay raise. The Pro 35 helper springs exceeds my expectations.
Easy installation,
etrailer customer support was great! Shipment to AK got damaged first time and they responded very quickly and sent me all the replacement parts I needed. The product is great and would definitely buy again if I swap out to a new truck!
I was very disappointed. etrailer only sent 1 of the two packages that was part of the complete item, shipped in two separate packages. I contacted them and they side it would be 45 days before they would receive the complete item.
I decided to return the first package and will try to find this item where I can get it sooner.
I have ordered other things from etrailer and have not had any problems.
The motorhome we own is famous for a droopy rear end, scraped bottom on any slope. We spent 2 months in Alaska including a trip to the Arctic Circle. The The Hellwig helper springs made a world of difference,no bottoming of the rear end.I have purchased a lot of products from etrailer and always found the to be; price competitive, good quality, fit accurate, in stock, fast shipping and provide before & after sales suppore.
Springs fit well. Seem to help with squat. Wish you did will call instead of shipping.
Hard to review a product the day after it arrives sometimes. I did however mock the overloads up on the truck to make sure everything was going to fit. I need these to help with tongue weight on a bigger fifth wheel rv I tow. I like the fact that I can adjust preload tension. I also have timbrens under the truck but need to correct some sway under windy conditions. Time will tell.
