Welcome to GM Upfitter Integration - Technical Bulletins

Technical Bulletins provide up-to-date information on issues that come up during the model year. These issues require a more immediate distribution of technical information than the annual Body Builder Manuals can provide. The need for a technical bulletin may be driven by one of the following:

  • Mid-year design change to the vehicle that affects upfitter modifications
  • Information from a GM Service Bulletin that specifically affects upfitter modifications
  • Frequent submissions involving one particular issue that many upfitters encounter

To find applicable bulletins select the appropriate information from the pull down menus for a specific search.
