So I have 5100's on top notch and a wheelers 1.5 AAL in the rear. Been about 3 years since the AAL and seems like it has sag a bit and now it's pretty much leveled if not lower in the rear. Anyhow, so I just want to know what you people would do, drop the front to the 4th notch OR put a 1" block in the rear. Is the extra 1" block combined with the 1.5" AAL safe? Need opinions please... btw, plan on 285's in the future and would the 4th notch of the 5100's clear them? If not then my only option will be 1" block in the rear.
