Compliant suspension
Front suspension is a coil-over-
shock design that has less mass
than the typical torsion-bar system.
Reducing mass improves ride
quality and handling everywhere
from rough roads to smooth high-
ways. The rear leaf-spring design
combines a smooth ride with out-
standing load-carrying capability.

The StabiliTrak stability control system and traction control are standard
on all 1500 models and select 2500HD models. The system has sensors
that read the position of your steering wheel, vehicle speed, brake pressure,
lateral acceleration and turning rate, then feed the data to an onboard
computer. If your Sierra is not responding adequately to your steering input,
the computer adjusts engine speed and applies brake pressure to any
individual wheel to help keep you on track. Its rollover-avoidance feature
can help mitigate roll forces. Its sensors are programmed to proactively
predict and help counteract vehicle "tip-up" on a flat road surface.

brakes and steering
For confident stopping in a wide
variety of conditions, a four-wheel
Antilock Brake System (ABS) is
standard. Rack-and-pinion steer-
ing provides precise performance
and an on-center feel. It also
offers low-speed assist for easier
maneuvering in tight spots. The
result is confident handling,
remarkable payload capabilities

and smooth, quiet performance
on the highway.
