2018 GMC Sierra 3500 Denali HD PERFORMANCE 
High-Strength Steel
Nearly two-thirds of the Sierra cab structure is made from high-strength steels. It’s a fortress of strength that contributes to the Sierra’s quiet cabin. We also use high-strength steel in our fully-boxed frame rails and major frame cross-members.
Automatic Locking Rear Differential
- When the differential senses a significant difference in wheel speed, it locks to turn both rear wheels in unison for added traction
- The Eaton® Locker senses a difference in wheel speed of approximately 100 rpm
