We just picked up our new 2012 Laramie today and I had the dealer install a set of Timbren rubber springs on the rear. I know the Timbren website recommends a gap of approx. 1" between the Timbren and the axle in an unloaded state. My truck has a gap of 2" or maybe a bit more. I'm wondering if this gap will close up a bit as the rear springs break in or should I do something to narrow the gap such as putting in an additional spacer? I'm hoping someone on the forum is familiar with this issue and can advise me. Thanks .
