The record

The Z71 RPO code named the GMT400’s off-road chassis package in 1988 and became a trim badge on the Silverado of 1999 and the Tahoe and Suburban of 2001; it sits below the Trail Boss and ZR2 today.

Research status: draft — identification, dates or figures could not all be pinned down; the summary says what is unresolved.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
