Thread: RPO codes?

  1. #1

    Default RPO codes?

    I looked in my glove box in my truck today, and theres a z71, and a z82 code in there. So does that mean its a z71 orrrr? Thanks!

    Z82 is heavy duty trailering equipment and when a truck also has z71 it has nothing to do with the suspension.

    ***ZW7....CHASSIS PACKAGE PREMIUM SMOOTH RIDE.....This Suspension uses a Conventional Suspension in the front, but the rear uses a self contained, self leveling Nivomat shock in the rear. ZW7 equipped trucks come with a softer spring in the rear since the Nivomat self leveling system does some of the work or holding the truck up.

    ***Z55....CHASSIS/SUSPENSION AUTORIDE PACKAGE.....This suspension system uses electronic shocks in the front that automatically adjusts to road conditions, becoming stiffer or softer as necessary. The rear will use an electronically controlled self leveling air shock that is monitored by ride height sensors and inflated remotely from an on-board air compressor.
