Hey Steve,I have the Rancho 4" lift on my truck,along with the Rancho RS9000 shocks. I like the lift kit,and the shocks are OK-I'll go with Bilstein 7100 shocks when I wear these out. I got a great deal on this kit last year with the rebate program that Rancho offered,I got a $750 rebate by buying the lift/shocks,so I really got the lift kit free,and paid for the shocks.
There were a couple hiccup's with the kit,but Rancho Customer Service was really good,and we worked through the problems fast/easy.
The Rancho lift does what I need it for,I play in the mud/river bottoms,climb hills on the deer lease,pull a trailer with a 10K GVWR. There are several companies that offer lifts for the PW that others consider better-Carli/Pure Performance/BDS/etc.,but the Rancho serves me for what I want,and didn't cost $2k-$5k.
