coil-over-shock front suspension
This fully independent system is precisely tuned
for improved handling. The front shock module
has been enhanced to increase road isolation
in response to even smaller vibration inputs.
A thicker spring isolator and a higher spring
rate produce a more controlled ride. The new
34-millimeter hollow stabilizer bar reduces
weight without sacrificing vehicle stability.
electric rack-and-pinion steering The new electric variable-assist power rack-and-pinion steering system on
Sierra improves efficiency versus engine-powered systems. The variable assist is tuned to provide less assist at highway
speeds for a solid on-center feel, and more assist for less steering effort when you’re maneuvering in tight spaces.
distribution of power Quite naturally, Sierra’s increased horsepower and torque call for an
enhanced way to transmit that power to the tires. That’s why the rear axle features a larger (9.5-inch)
ring gear on the V-8s, and the redesigned rear axles are now stronger and beefier to handle the increased
power capacity. This robust axle design also provides improved durability.

A Sierra is crafted from thousands of components, yet their sheer brilliance comes from how they seamlessly work in
unison. Precision integration of tires, wheels, chassis, suspension, steering, braking and axles helps provide greater command and control of your Sierra. For the all-new
Sierra, the challenge was far from simple. Engineers were asked to reduce weight to transfer increased engine output to the road and build upon Sierra’s already impressive ride
and handling qualities, all without diminishing its legendary power, capability and durability. The successful result epitomizes the GMC philosophy that just being good
enough is never enough—there are always new goals to overachieve.

corrosion-resistant duralife™ brake
rotors To reinvent the brake rotor, GMC engineers
used Ferritic Nitro-Carburizing (FNC) technology,
which can double rotor life. FNC is a patented GM-
exclusive corrosion protection process designed
to prolong rotor life by hardening the rotor surface.
It provides protection against rust to help prevent
steering-wheel shudder when applying the brakes.
