I-CAR · May 23, 2018 · Chevrolet, GMC
Summary
The 2019 Chevrolet Silverado features a significant weight reduction of 449 pounds through the increased use of high-strength steels and aluminum. A major structural change from previous models is the transition of the front structure from a bolted-on design to a welded assembly to improve corrosion protection and reduce weight.
What to do on the job
Identify and verify the welded front structure design on 2019 and newer Silverado models, ensuring proper welding and corrosion protection procedures are followed rather than attempting to bolt on replacement components.
How to use it
Use this document to justify the transition from bolted to welded repair procedures on the front structure of 2019+ Silverado models, and to support the necessity of comprehensive corrosion protection measures required for welded steel and aluminum assemblies.
