These were on a 2004 Suburban 1500 4x4 that I recently purchased and have no need for them. Compared to standard shocks they had 3 to 4" of extra lift without a load on. The book says only Suburbans Tahoes and Yukons is what they will fit from 2000 to 2006. New ones at Napa or Oreillys are $250 for a pair. Texting and emails will be ignored. Call me and leave a message. KGB near Settlers Bay Lodge.
