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:

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:

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



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:

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:

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.

They have a 3,500 lb capacity and come with a lifetime warranty.

  • Slide-Out Support Recommendations for a 2022 Thor Chateau 24F
    Hey Hoang, thanks for reaching out! The Hellwig Load Pro 35 Heavy Duty Helper Springs # HE72XR is for a handful of vehicles older than 2000 so it won't fit your Thor motorhome with a 2022 Ford E-Series Cutaway chassis. If you're needing more support than what the SumoSprings are offering then I recommend swapping those out with the Timbren Rear Suspension Enhancement System # TFERSD which has more rigidity. There are some of the leaf-spring style options that could fit on your motorhome,...

  • How to Pick Out the Correct Leaf Springs for a 1997 Ford E-350
    The amount of leaves on a spring is not really the important bit when you go to replace your leaf springs. Instead, you'd want to go by capacity and the spring measurement. So for instance, if you needed a leaf spring with an 8,000 lb capacity and measured 24 7/8" long then the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles # DX74XR. Let me know below what you're looking for below and I'd be happy to help you.
