Even a modest trailer or bed load can make the rear end sag and steering feel loose. These Hellwig Load Pro 15 helper springs add up to 1,500 lbs of load-leveling support to your factory leaf springs. They keep your ride height even when towing or hauling light loads and help maintain stable braking, cornering, and headlight aim.
Bumpy roads and uneven weight can make your truck bounce or sway. These helper springs flex with your existing leaf springs to limit body roll and reduce sway. The design helps smooth out the ride so you stay in control through curves, dips, and uneven roads without harshness.
No two loads are exactly the same. The adjustable U-bolt setup lets you dial in tension for different cargo weights, while the driver’s and passenger’s sides can be adjusted independently for uneven loads. That means a level stance and steady handling whether you’re carrying tools on one side or hitching up a small camper.
These helper springs are made from strong steel for long-lasting performance. The silver vein hammer tone powder coat finish resists corrosion so they hold up through weather, work, and road grime. All necessary mounting hardware is included, and the bolt-on design makes installation straightforward with basic tools.

Ratings & Reviews
Had problems but they straightened it out fast
Delivered quickly, all parts were there, installed with ease.
I was looking at the product that is rated for 6,000lbs, but I read the reviews and a guy had the same truck as mine and he said the ride was too ruff. I decided to go with this Load Pro 15 and it works great. The ride is a bit more tight and I like it...
I actually ordered these after I lowered my vehicle, I found when I have passengers in the vehicle the back tires would rub on hard turns and bumbs. So I installed these helper springs and they work great, the rear leafs dont sag now and its alot stiffer for my trailer and when I have a load in the vehicle.
Thay work great and easy to install!!!
The u-bolt plates hole where misaligned by a little over 5/8" overall, they where set apart to far. I had to use a cabinet but to slot the holes to allow the u-bolt to pass through the plates. The average person would not have the tools to do this. I don't know if they sent the wrong parts of it's a design fault. But installation went from 10 minutes to about an hour. Definitely something they might want to look into.
