Sierra Denali features an exclusive Adaptive Ride Control suspension system designed to provide premium driving refinement with exceptional responsiveness. It employs sophisticated sensors to monitor road conditions and chassis responses in real time, enabling adjustments to active dampers every 2 milliseconds.

The next generation 2019 Sierra debuts a GMC exclusive, industry-first MultiPro Tailgate that is the segment’s most innovative tailgate ever. Standard on SLT and Denali, the MultiPro Tailgate features six unique functions and positions, offering enhanced second-tier loading and load-stop solutions, a standing workstation mode and easier access to items in the box.
The MultiPro Tailgate also incorporates a step entry and egress mode that, when paired with the assist handle, offers both step and seated functionality, with a maximum weight capacity of 375 pounds (170 kg). Ease of use is enhanced with two buttons on the tailgate handle that allow convenient inner gate release.
This multifunctional tailgate offers proven strength and durability, having undergone more testing and validation than any tailgate in GM’s history. Sierra is the first and only truck to offer the MultiPro Tailgate, providing premium truck customers the ultimate flexibility. MultiPro Tailgate will be standard on Denali and SLT.
The cargo boxes also offer best-in-class cargo volume — 63 cubic feet (1,784 liters) on the short box, as well as additional tie-downs and a new, available 110-volt power outlet. The bed continues to be made of roll-formed, high-strength steel, yet a revised alloy offers 50 percent more strength than the current model.
The 2019 Sierra Denali will offer, later in the model year, an available GMC exclusive and industry-first carbon fiber box — the CarbonPro — developed to increase durability, efficiency and functionality of the truck. It replaces the standard steel inner panels and floor with a lightweight, purpose-designed carbon fiber composite that offers best-in-class dent, scratch and corrosion resistance.
