Am mildly modifying my stock rig...Goodyear MT/Rs 265/75/16 and shrockworks sliders. Looking into front and rear air locker's and aftermarked shocks down the road. I am very wary of any kind of lift because I do not want to alter the structural integrity or suspension dynamics set up by nissan. I figure that stock and with the new tires I should have about 11 inches of ground clearance tops. Is this a sufficient setup for some mild to intermediate offroading...or is a lift absolutely needed? I am not looking to go insane in the mudpits and rock gardens, but I would like to hit some trails and see what my truck can do. Your opinions would be appreciated!!
