I have a 5" Rough country lift, and I was wondering if i could put a 1", a 1.5", or a 2" spacer on it and still be ok without pulling my axle back too far. I'm running 36's right now and have PLENTY of clearance and I want to run 38's. I have enough clearance now, I just like my clearance and want to keep it when I put 38s on it. any help would be great thanks!!
