The Best "Overload " Springs - 21 Ford F-150 4x4

2021 Ford F-150, 4x4, 3.5 Twin Turbo, Ecoboost. 10,000 lb semi-trailer, tongue weight 1500 lb. I've tried airbags which worked fairly well but still resulted in a bumpy ride with and without a load. I tried the jounce style overdrive rubber blocks and they rode very hard when the truck was loaded. The RAS springs were installed in about 20 minutes per side. I made a 1.5mm gap and they work great. I am currently towing my 5th wheel on a 12,000 mile car trip. These progressive springs offer a very comfortable ride with or without a trailer. Addendum: Only driven 10,450 miles but the springs worked perfectly.

Pros
  • Excellent Performance
Cons
  • No Insurance
