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.

HELLWIG HELPER SPRINGS
Good springs, and great customer service. Came with messed up ubolts, called customer service, immediately sent new u bolts.

Great product, poor instructions.
Product works as intended, installation was made more difficult due to incomplete or poorly thought out instructions. Before assembling, thread all nuts off and onto u-bolts to "chase" u-bolt threads. Some threads likely damaged a bit during the electroplating process. The springs themselves are high quality and give the desired result, but you need to figure out proper installation including which bolts go where as you go. Not hard but could be made to be much easier by decent instructions.

Be aware of hardware issues
The springs themselves seem to work as intended, but the u bolts and hardware provided is junk. You would think with all the other reviews with same issues the company would have their QC do something with providing a better product

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

Hardware is almost unusable!
The leaf spring itself seems pretty descent, but the hardware is absolute junk. The u-bolts use some non standard thread pitch that looks like someone had made with a bench top lathe. The threads aren't really thick enough to really hold any descent amount of torque. Just be careful when mounting the hardware they will strip. Probably better off investing in some other u-bolts if you decide to go with this kit.
