This GM 226 HD transfer case is rebuilt with new bearings and updates to prevent future problems. It comes with shift motor/ encoder motor. It is from a 2004 Trailblazer. I purchased a vehicle that this came with, the transfer case ended up not being needed to repair the vehicle and I am selling this separately. It fits 2002-2008 Trailblazers, Envoys, Raineer, bravada, and some isuzu's. Phone calls only please text messages and emails will be ignored. 9zero73zero115zero6
