Well I installed the front portion of my Rancho lift and The ride is FANTASTIC!
I bought the truck with worn out Rough Country leveling coils and they rubbed the top 2 coils so I swapped them for a set of coils from a E350 van that were the same length. These however were thicker and didn't squat as much which lifted it more and threw off the alignment. They also didn't seat in the buckets right and creaked and popped.
The Rancho coils along with the extended Radius arms make the truck ride Fantastic. The Resi Shocks I got a deal on (100 for 4 new in the box) weren't for my truck but ride great and are working very well. Thurs. I will install my Add-A-Leafs and 35's
