I have a set of rear QA1's model number MU7855P with about 2,000 miles on them. I bought them because they are shorter than the bilsteins and my truck was lowered 3.5 inches. I recently raised it back up and put the bilsteins back on so I have no need for these. I bought them brand new from Paradise Racing a couple months ago and they were taken off today. There are no problems at all with them. Asking $210 shipped plus paypal fee.
SOLD!!!!
