IMO 33s and the Rancho 4" kit will look small. Everything I have read says the rancho kit is closer to 5" of lift after installation.
Don't be scared of a body lift. They are no different than a standard suspension lift. The main purpose of any basic suspension lift kit is to provide more ground clearance (same as a body lift). Some guys measure ground clearance from the ground to the frame. I measure it from the ground to the axles/suspension components. The only way to gain more ground clearance, as I measure it, is to run larger diameter tires. For me, I wanted to run 34s with out spending over a grand in a suspension lift and I have accomplished this task with only spending $400 on new struts and shocks. Sometime this winter, I will be installing a 2" body lift and when I am done, it will all look factory and I will still be able to tow my 4500# boat. I had a 2" body lift on a Jeep for 35,000 miles with no issues on or off road, and I have a 1" body lift on my wife's jeep (25,000 miless) with no issues on or off road. The problems I have seen with body lifts have mainly been associated with older vehicles that have weak/aged body mounts. I have also seen issues with homemade kits.
