THE STORY BEGINS AT THE END OF THE ROAD.

The best way to appreciate the engineering that went into the new

Sierra HD suspension is when the road is at its worst, or when there

is no road at all. With a redesigned fully independent torsion-bar

front suspension on every model, and a completely revised rear

suspension, Sierra HD removes the compromise between ride

comfort and load capacity, so you can trailer or haul heavy loads

with a comfortable margin of control.

All Sierra HD models have a new Independent Front Suspension

(IFS), designed for the constant punishment of heavy-duty use.

Built extra-strong from extreme-duty components, it gives both a

smoother ride than conventional beam-axle suspensions and up

to a 6000 lb front axle GAWR

that is unsurpassed by competitive

HD models.

No other competitor

in the class offers an

available fully automatic

locking rear differential,

for on- or off-road use.

When the Eaton

Locker

senses a difference in

wheel speed between left

and right rear wheels of

approximately 100 rpm,

it locks both rear wheels

to turn in unison for

added traction.

Vibrations are the enemy

of comfort. That’s why

Sierra HD Extended

and Crew Cab models

are cushioned at the

rear cab frame attach-

ments with hydraulic

body mounts.

The more load your HD takes, the more its springs step up to the

challenge. New rear leaf springs are 3 inches wide—two-stage for

2500 models, and three-stage for 3500 models.

Capacities and weight ratings are dependent upon model, engine, transmission and GVWR combinations.
