Do What They're Designed To Do

First off, the biggest thing is to read the installation instructions. The springs are directional, and the U-bolts are different sizes depending on where they go.That being said the installation is fairly straightforward, there are some YouTube videos that will help. Adjustment is kind of trial and error, I highly suggest going to your local dealer and doing some unloaded measurements on new trucks to get the ride height correct. Our use was on an F150 police package, which carries about 600 pounds of gear in it. It wasn't sagging badly, but even the dealer was a bit freaked out at the amount of sway in the rear suspension. We installed these springs, got the ride height to where it would be unloaded, and installed the Hellwig sway bar. The difference is night and day, the ride is much better and the truck handles better than it did before the equipment was installed.

Does the job

The installation is real simple and straight forward. I wasn’t looking to raise the rear of the truck at all or affect the current, unloaded, ride and that is exactly what these do. What I wanted was to help balance the load when I have my travel trailer attached and it works perfect for that. Truck loaded, trailer attached and no helper spring hitch height is 15.5 inches. Add the helper spring same setup the hitch height is now at 17.5 inches. The unexpected benefit was it transferred a little more weight to the front of the truck which now makes it feel more stable. The only down side is when unloaded the attachment hardware has a tendency to rattle when going over bigger bumps. To counteract that I installed some rubber washer under the metal washer, then added some rubber tubing over the sides of the U-bolts. Rattle is gone!

Quality Constuction

This item says made in USA and it shows . Well made and easy to install . It fit perfectly . I adjusted the springs up to almost maximum and the ride doesn't seem to be affected on my 2016 f-150 crew cab . There is no rattle noise from the springs while driving around empty . I haven't actually loaded it yet which I bought it for hauling my camper , but I think it would sure help support the 400lb tongue weight .

Disappointed!

Had these installed about three years ago.I still get much sag when I hook my 800lbtongue weight trailer to the truck.It is no different than without them.

Read the directions first . Also use a thread locker

Follow the directions the kit has different size u-bolts and need to be placed accordingly. Also while you are setting preload put some thread locker on the threads on the front and rear u-bolts otherwise they will loosen up

Missing 4 of the u-bolts, but came with all other hardware for them.

Seemed to be a return that was sent

Items werent all in plastic packages and one u-bolt was stripped, I had to go buy a new one so I incurred another $20 bucks expense, was easy to install but disappointed that I had to buy additional u-bolt, the one sent to me was obviously used….

Easy to install

Installed on my 2016 F150 and now with a heavy trailer that used to lower my truck a lot it lowers it only 1 1/2 " and stopped the bouncing up and down completely super happy

Poor quality from hellwig

One U-bolt missing and the other one is not brand new. The seller provide me another set with free shipping.

A better daily ride

Looks the simplicity of mounting and the fact that they don't engage until needed - hence. A better daily ride.
