So I was at the Nissan dealer earlier and saw a 2007 OR Xterra on the lot along with the 06 OR. I parked in between the 07 and 06 to compare ride height against mine, and wow big difference. My front end sits 2" higher, of course, with spacers. The rear however is about 1" lower than the 06 OR!! It sits even with the 07 tho, strange. I have AC shackles and it still sits lower than the 06, but strange how it is even with the 07. I asked a salesman why, but we all know that they dont know anything. I measured the shocks on both and they are the same length, but 1" longer as compared to my S model. My concern is, did my rear springs sag already? I hope not! I only have 17k miles on it! Any suggestions? Complaints?
