Features to know about

Stay Level While You Tow: 3,500-lb Heavy-Duty Load Support

When you hitch up a big trailer or fill the bed with heavy gear, rear sag can throw off your steering and braking. The Hellwig Load Pro 35 helper springs add 3,500 lbs of support above your factory leaf springs to keep the rear end level and stable under weight. They prevent squat when towing or hauling heavy loads, so your ride height and control stay steady even when the truck is working hard.

Cut Down on Sway and Bounce: Constant Load Stability

Heavy loads can make your truck sway or bounce down the highway. These custom helper springs flex with your existing leaf springs to reduce body roll and absorb movement while keeping the chassis firm and planted. The result is steadier handling through curves, smoother ride control, and better road feel whether you’re pulling a trailer or carrying a full bed of gear.

Handle Uneven Loads with Confidence: Independent Adjustment

Not every load sits evenly in the bed. The Load Pro 35 lets you adjust the driver’s and passenger’s sides separately so each corner supports its share of the weight. That balance keeps your truck level side to side, reducing uneven tire wear and keeping braking and handling more consistent when one side is heavier than the other.

Install It Once and Get to Work: Bolt-On Kit with Durable Construction

The custom mounting kit bolts right above your factory leaf springs for an easy, secure fit—no complicated setup required. Each spring set is built from heavy-duty steel with a silver vein hammer tone powder coat finish that resists corrosion for long-term use. Once installed, you’ve got dependable suspension support that stands up to constant hauling season after season.

Video Transcript for Checking Out the Hellwig Load Pro 35 Heavy Duty Helper Springs with Custom Mounting Kit

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the Hellwig Load Pro 35 heavy duty helper springs with the custom mounting kit. Now, this is a custom fit part. It is designed to fit the 1994 to 2002 Dodge Ram 1500 and 2500 and 3500 trucks. Also fits the 1977 to 1991 Ford F-100, F-150 trucks, and the 1977 to 1997 Ford F-250, F-350 trucks.

Now, on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle and it'll show if this will work for your application. Now, this Load Pro 35 spring set features a nice full-time spring rate design, which is ideal for vehicles or fleet applications that consistently carry a heavy load day in and day out. These offer a full-time spring rate, which will adjust to the load on your vehicle for an improved ride, won't affect a ride while it's unloaded. The custom helper springs upgrade your factory leaf springs to reduce sway and body roll. These will prevent sagging when you're towing or hauling heavy loads.

It'll help extend the life of your factory suspension, your tires, and your brakes. Now, these four helper leaf springs will flex with the factory leaf springs to limit bouncing, while providing optimal stability, and they're pretty easy installation. Basically, they'll just bolt above your factory leaf springs. The drivers and passenger sides can be adjusted independently for uneven loads. These are a custom installation kit.

As you can see, this comes with the included zinc plated hardware for installation. One note I do wanna mention if your vehicle's equipped with a factory contact overload, it may need to be removed before installing these new helper springs. What I would recommend is to consult your installation guide. These parts are durable steel construction. They ensure a nice long lasting performance.

And what I wanted to point out, let's zoom in here, the finish on it, they use a unique silver vein hammer tone powder coat finish. This will resist corrosion. Basically you can see the mounting plates and the springs all have this silver vein hammer tone finish on it, protects them and makes them also look good. These parts are made in the USA. Few specs, the weight capacity is 3,500 pounds. One note I do wanna mention is these Hellwig helper springs will not increase your vehicle's weight carrying capacity. But that should do it for the review on the Hellwig Load Pro 35 heavy duty helper springs with the custom mounting kit.

GREAT CUSTOMER SERVICE



by:

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.



by:

Great service,people are great to work with, they back every they sell.
I've used E-Trailer for years



by:

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.



by:

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.



by:

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.



by:

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!



by:

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.

  • Hellwig Helper Springs for 2013 GMC 2500 2WD
    Thanks for letting us help Daniel. We carry two sets of Hellwig helper springs that are compatible with your 2013 GMC Sierra 2500 2WD. The main difference between them is their load support capacity and intended use. The Hellwig Load Pro 25 Progressive Helper Springs # HE73XR provide up to 2,500 lbs of load support. These are considered more of a general-duty option and are commonly used on 1/2-ton trucks or applications where only moderate additional suspension support is needed. For...
