Is GM Giving the Silverado and Sierra an Independent Suspension?

Chevrolet’s 2021 Tahoe and Suburban are slated to debut soon and both models are coming with advanced, independent rear-suspension design. The new setup enhances the overall ride quality and vehicle handling and has paved the way for a dramatic increase in the SUV’s cabin space for passengers and cargo.

And now that that’s in the bag, consumers are curious to know if General Motors is also installing the same independent rear suspension on its priced trucks, the Chevrolet Silverado and GMC Sierra.

The rear suspension in GM’s full-size SUVs is expected to be powerful enough for half-ton pickup duty and they are said to have been “incredible” for the Tahoe and Suburban, according to Tim Asoklis, chief engineer for both models.

“These vehicles wchevrill have over 4 million miles of additional road exposure compared to just doing the durability [testing],” Asoklis said. “And once we’re done, we take these vehicles and we completely dissect them. We look for any and all issues,” he added.

Asked if the independent rear-suspension design used on the SUVs is also durable enough to be used on pickup trucks and withstand extreme towing, hauling, and off-roading, Asoklis said, “Oh, absolutely.”

He, however, declined to mention whether GM is planning to add the same suspension to the Chevrolet Silverado and GMC Sierra. But he did note that if the suspension system design was to be added to the pickups, it’s likely going to require a complete re-evaluation as it will need a different application from a full-size SUV.

If the Silverado and Sierra do end up getting the independent rear suspension, complete with magnetic dampers and adjustable airbags, the two models are going to be tough competitors for other automakers. It wouldn’t even be surprising if GM ends up overtaking the Ram 1500 in the segment, considering that it still has a live rear axle despite already being fitted with an air suspension system.
