SUSPENSION
Front independent suspension
with torsion bars allows high
gross vehicle weight ratings and
superb load-carrying capability.
It also helps produce a smooth
and comfortable ride. In the
rear, semi-elliptical multileaf
springs (two-stage on 2500HD,
three-stage on 3500HD) and gas-
charged shock absorbers help
produce a smooth ride under
loaded and unloaded conditions.

Z71 OFF-ROAD SUSPENSION PACKAGE
The legendary Z71 Off-Road
Suspension Package for Sierra
HD models (available with SLE
or SLT trim, not available on Dual
Rear-Wheel models) includes
Z71 Off-Road Suspension ( with
a larger front stabilizer bar than
1500 models), the Eaton Auto-
matic Locking Rear Differential
and skid plates. (See page 09 for
more details.)
ROBUST CROSS-mEmBERS
LOCKING REAR DIFFERENTIAL
The available Eaton Automatic
Locking Rear Differential is
designed to improve traction at
lower speeds. It engages when
the speed difference between
the rear tires reaches approxi-
mately 100 rpm. Once engaged,
both rear wheels rotate at the
same speed, providing more of
the driveline's torque to the tire
with better traction.
