Parts fit perfectly love the subtle lift the truck should come from the factory like this. 2 downsides 1st be careful during install you have to really push down on the lower control arm which in my case pulled the cv boot off the driver side. 2 you will definitely need wheel spacers because the inside of the tire rubs the new upper control arm.

Makes my truck sit at the perfect height and will now fit 35's. Install was fairly straight forward but should have come with rounded u bolts for the rear. It should be noted as well to be extra careful with front reinstall I pulled the CV boot off while forcing the lower control arm down.
