i'm not sure about a letter in the vin, but a true z-71 will have bilstein shocks, and skid plates under the engine, tranny and transfer case. not sure about the 06's, but 08 z-71's also have an automatic locking rear differential.

the Z71's also have the aluminum block HO 5.3 where the regular 1500's have the iron block.
