Product Details

The Hellwig LP-35 Load Pro Helper Spring is engineered for truck owners who regularly haul heavy loads and need reliable load support. This progressive helper spring system provides up to 3,500 pounds of constant-rate load leveling capacity, helping to reduce sag, improve handling, and maintain proper vehicle stance when towing or hauling.

Key Features:

  • 3,500 lb constant-rate load leveling capacity for heavy-duty applications
  • 2-leaf spring steel construction for durability and long service life
  • Progressive design allows adjustment of ride height and spring rate via outer U-bolts
  • Engineered for full-time use by serious haulers and towers
  • Bolt-on installation with no drilling or cutting required
  • Backed by Hellwig's lifetime warranty

Important: Mounting hardware kit sold separately. The adjustable U-bolt design allows you to fine-tune the spring rate and ride height to match your specific load requirements, making this system versatile for varying cargo weights.

It was easy to find the part for the vehicle you are shopping for, quick and simple to checkout, I will be ordering from autoplicity more often...we'll have to wait and see how long it takes to get to my residents...

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

very easy

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
