Chevrolet Trailblazer & GMC Envoy 4.2L Engine - 2002-2005. All other parts that may be provided are "Accessories and Extra Parts.". Install and replace timing belt if necessary, if your engine has a timing chain it is set and ready for installation.
Engine arrived very clean highly impressed and so far worth the wait. Just dropped it off at the mechanic shop so waiting on the install will update review once it’s up and running.
