no im not saying you dont need a lift, im saying it doesnt much matter what kind, like if u get RC as opposed to RE or BB and BL as opposed to LA, its mostly about onroad comfort untill you get into intense rock stuff, or like 6+ in of lift
I'd go with some wide Boggers and 6" of lift (4 suspension and 2" bl)
In my opinion for sand Boggers is the biggest choice of sizes i've ever seen and they vary from pizza cutters to like 16-17" wide (not tall)...
With the right air pressure a 2WD will go just about as many places as a 4WD in beach sand. You don't want get boggers for the beach though. Mud tires just dig down in the sand, an all terrain tire will do much better.
