From its frame to its sheetmetal, the 2019 Chevrolet Silverado 1500 is all-new from the ground up. Also new is the truck’s suspension system – which in some models features unique carbon composite rear springs. Here’s a closer look at the 2019 Silverado suspension.
It all starts at the frame: the 2019 Silverado features a stronger and lighter frame that allowed engineers to create an all-new chassis, delivering improved ride, handling and reduced mass.
At the front, the independent short-long arm suspension now features new forged aluminum upper control arms that provide better wheel alignment and weigh less than the stamped components that they replace. At the rear, the 2019 Silverado suspension continues with a live rear axle setup, but it has been reengineered. Even more importantly, some models will be equipped with carbon composite second-stage springs, which are similar to the technology that is used in the Corvette.
Carbon Composite Springs
A carbon composite spring deliver two primary advantages over a traditional metal spring: they are lighter and they can be tuned to perform better.
In the case of the 2019 Silverado, the carbon composite springs save 12 pounds of weight per side, or 24 pounds per vehicle. That contributes to the significant decrease in curb weight of the 2019 Silverado, which is up to 450 pounds lighter over the previous K2 platform model.
What’s more, the carbon composite springs allow engineers to tune and optimize the dynamic properties more precisely over a traditional metal spring. And though anyone outside GM/Chevy engineers have yet to drive the trucks and experience the 2019 Silverado suspension system, GM product chief Mark Reuss has stated that it will be “a lot of fun to drive”.
It’s currently unclear which 2019 Silverado models will feature the carbon composite springs. We expect to find out much more about the new Silverado, including the 2019 Silverado suspension, after GMC announces its all-new 2019 Sierra on March 1. Until then, stay tuned to GM Authority for around-the-clock Silverado news coverage.
