With Hellwig’s track record of quality manufactured products being used in the most severe driving environments possible, you will have peace of mind when you install Hellwig suspension components on your vehicle knowing it will be ready to tow heavy trailers or handle the curviest roads without drama.

  • 100% manufactured in a ISO 9001 quality certified factory in USA
  • Quicker and easier installation with available step bracket versions
  • Minimizes axle wrap
  • Lessens suspension fatigue and enhances vehicle stability when loaded or towing

I have a 2000 Ford F-150 Harley-Davidson edition with a tow capacity of 4,000, by how much will the helper springs increase the tow capacity?Mariano C.Apr 07, 2022
Best Answer:Hi Carlos, I'm more than happy to help. Omar's answer is correct. Helper springs help provide greater control and stability, not increase the towing capacity. You can use the link below to order this if you are interested. Have a good one. <a href="https://www.carparts.com/helper-spring/hellwig/h63991?can=cpab2020_20220407" target="_blank">https://www.carparts.com/helper-spring/hellwig/h63991?can=cpab2020_20220407</a>

My leafs have flattened out.  Will this help with the recurving of my leafs?Todd W.Dec 11, 2022
Best Answer:Hi Todd, I'm glad to assist you. No. This helper spring adds more load capacity but it does not correct or helps to rectify your sagging leaf springs. You need to replace your factory leaf springs with brand-new ones. For us to carefully check and be accurate on the part you need, please provide the complete information of your vehicle (year, make, model, submodel, and engine size). The VIN would be much helpful. I hope this helps.

I have a 2003 toyota Tundra Limited 4 wheel drive... what is the difference between the 550 and 991? I pull a toy hauler camper that probably weighs about 5500 lbs when it is loaded with our camping stuff and a motorcycle or 4wheeler etc... sometimes I also put a 4 wheeler in the bed of my truck when towing. Which of these would work for me? thanks?Cort H.Jul 28, 2022
Best Answer:Hi Cort, I'm pleased to assist you. The 550 has a load capacity of 500 lbs and 991 at 2000 lbs. Upon checking, we currently do not have helper springs for about 5000 lbs compatible with the 2003 Toyota Tundra. You may want to consider purchasing heavy-duty industrial-strength cleaning wipes, good to have around your home and garage. Click on the link below to see and order while supplies last. You'll get a 30-day post-purchase price match guarantee with your order. I hope this helps.

Helper Spring, Set Of 2
great product
Great product easy to install I put these on a 2002 f150 fx4. Much improved when loaded or pulling trailer. Truck handles better as well with less role.

helper spring installtion
The helper springs sure increased my load capacity.Not sure why Toyota did not install at the factory.I can carry 2500lbs now with know problem.I recommend to buy new u-bolts for the existing springs.This will speed up the installation time by at least 50%.And be a much safer job when completed.
