Just wanted to give a heads up. Purchased some 9000xl's for my '03 Avalanche today and found them for under $90 apiece at Rockauto. There's also a 5% discount code at http://www.retailmenot.com/view/rockauto.com and Rancho is doing their rebates again. I am not affiliated with Rancho or Rockauto but wanted to pass the info that I found. I spent just under $325 for 4 shocks and they should qualify for a $100 Visa card.
