Sectioning and Partial Part Replacement: 2017 Chevrolet Silverado - UPDATE
I-CAR · October 14, 2026 · Chevrolet
Summary
This article outlines the sectioning and partial part replacement guidelines for the 2017 Chevrolet Silverado, highlighting that while outer uniside sectioning is permitted, the front lower rail requires a specific partial replacement of both rails and the crossmember, and the rear rails cannot be sectioned at all.
What to do on the job
Perform full part replacement for the rear rails, and ensure both left and right rails plus the crossmember are replaced if performing a front lower rail partial replacement.
How to use it
Use this document to justify the necessity of full rear rail replacement and to support the inclusion of both front rails and the center crossmember on estimates when front rail damage is present, as partial sectioning of individual front or rear rails is not permitted by GM.
