The only thing a Z71 package has that the other trucks can't be optioned out for is Rancho shocks. The Z71 package comes with skid plates and a high capacity air cleaner, but you can get those options on any GM full-size truck. It's only the shocks that cannot be optioned out on there own.
The biggest difference now, is that when you order a Z71 you need to get an LT truck with a 5.3 or 6.2, which makes the package a $6-8k (cdn) upgrade. You use to be able to get the Z71 package on base model trucks, with a 4.8 and floor shift 4x4.
