Z71 is an off-road trim package that is available on some Chevrolet Suburbans, Tahoes and pickup trucks. While the exact features of a Z71 trim package can vary from one model to another and one year to another, the package generally includes wider tires and a limited slip differential.
The interior of the Z71 trim package is a little different from other Chevy trim packages, such as the LT and LTZ. The first Z71 trim package debuted in 1988. The details of the 2015 Z71 trim for the Tahoe and Suburban are set to be announced when the vehicles debut in fall of 2014.
