Hi, everybody, Andy here with etrailer.com. Let's take a look at these Hellwig Load Pro 35 Heavy-Duty Helper Springs. Now, these springs have been designed to fit your 2001 to 2010 Chevrolet Silverado, and GMC Sierra 3500s, then your 2007 Silverado and Sierra, both the classic and the new body 3500s. On custom-fit parts such as these springs, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer.com. Simply input the year, make and model of your vehicle, and our Fit Guide will confirm if this will work for you or if we have something comparable that will work for you. So, these custom helper springs have a load leveling capacity of 3,500 pounds, and they're going to install above your truck's rear factory leaf springs to help reduce sway and body roll, while preventing sagging when you're towing heavy loads, and they're going to extend the life of your factory suspension, tires and brakes.
So, these springs actually flex with your leaf springs to help limit bouncing while giving you optimal stability. And this is going to be a bolt-on installation, again, above your factory leaf springs with the included custom installation kit, and as I hope you can see, I kinda have everything here loosely installed, and this is basically what it's gonna look like when you have it installed into place. Got the U-bolts and everything here, so just kind of just loosely installed just to show you what these are are going to look like. So, the driver's and the passenger's side can be adjusted independently for uneven loads. Now, a few things I wanna point out.
If your truck is equipped with a brake fluid proportioning valve, these constant rate springs are not recommended. Only progressive rate helper springs should be used in that case, and if your truck is equipped with a factory contact overload and may need to be removed before installing these new helper springs, of course, you wanna consult your installation guide, and then you don't want to install these springs on vehicles with composite or plastic leaf springs, because these springs are so robust, it could fracture or damage or break those composite or plastic leaf springs. Now, these are made here in the USA of a durable steel construction, so that's going to ensure long-lasting performance, and they do feature this silver vein hammer tone finish that's gonna help resist rust and corrosion. Again, the weight capacity is 3,500 pounds, but I do wanna make you aware of the fact that these helper springs do not actually increase your truck's weight carrying capacity, so you wanna make sure you're not exceeding your manufacturer's recommended weight limit. Instructions are also included to guide you through the installation process.
These do have a lifetime warranty from Hellwig, and I think that's gonna wrap up our look today. I do hope that it was helpful for you. When you get these installed, let us know how they're working out for you. Send us a review, drop us an email or give us a call, and we'd also like to see pictures as you're going through the installation as well, just to see how these worked out for you, and again, we'd love to hear how you have received the benefit of these and how you feel these are treating you. Well, again, my name is Andy, thank you for joining me.

Great Product
GREAT CUSTOMER SERVICE
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.
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.
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.
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.
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!
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.
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.
