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 .

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.

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!

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.

Tried to put these on my 2019 F150 to help with some larger than expected loading. They barely lifted the truck at all. Probably got about 5/8" of lift, and that may be a bit generous. Not enough for this situation. They did make the truck feel a bit more secure with the load, but not nearly as much as I wanted. I also noticed that the added spring (tightened to the maximum allowable amount) hit the shock mount when passing over a moderate road bump. Adjusting the position of the added spring forward or aft would not have changed much in regard to interference with the shock mount. We had to remove these springs, and are returning them. The seller, 'southerncarparts', has approved the return, and they should be commended for that. Thank you to them.

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

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