I am very pleased with this product, installation was easier than expected.
Couple you tube videos is all you need for this leveling kit. Was very easy and looks great!!
I purchased and installed this kit on my 2013 GMC Sierra 2500HD Duramax. It helped to considerably level out the front of the truck as well as give additional clearance for larger tires. I have stock GMC 20" wheels with 275/65/R20 BF Goodrich all terrains installed. If you use a tire size calculator it is basically a 34. A lot of people run the 305/55/R20 which are a 33 and 2" wider. I prefer less width more height. No rubbing issues even with the additional weight of a 8'6" Fisher XV2 in the winter time.
I have had it for about a year, did exactly what I wanted it to do by leveling the truck. I have used READYLIFT products several times. Never disappointed yet.
