If equipped, the electronic TSC recognizes a swaying
trailer and automatically applies individual wheel
brakes and/or reduces engine power to attempt to
eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball
or some other connecting point of the vehicle. These
kinds of hitches are commonly used to tow small and
medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the
tow vehicle's front axle and the trailer axle(s). When
used in accordance with the manufacturer's directions,
it provides for a more level ride, offering more consis-
tent steering and brake control, thereby enhancing tow-
ing safety. The addition of a friction/hydraulic sway con-
trol also dampens sway caused by traffic and
crosswinds and contributes positively to tow vehicle and
trailer stability. Trailer Sway Control (TSC) and a weight-
distributing (load equalizing) hitch are recommended
for heavier Tongue Weights (TW) and may be required
depending on vehicle and trailer configuration/loading
to comply with GAWR requirements.
WARNING!
•
An improperly adjusted weight-distributing hitch
system may reduce handling, stability and braking
performance and could result in a collision.

WARNING!
•
Weight-distributing systems may not be compatible
with surge brake couplers. Consult with your hitch
and trailer manufacturer or a reputable Recre-
ational Vehicle dealer for additional information.

ADJUSTMENT
Towing With 2500/3500 Air Suspension
1. Position the truck to be ready to connect to the
trailer (do not connect the trailer).
NOTE:
Standard Ride Height (SRH) or Alternate Trailer
Height (ATH) can be used. The vehicle must remain
in the engine running position while attaching a
trailer for proper leveling of the air suspension sys-
tem. It may not be possible to enter Alternate Trailer
Height (ATH) while lightly loaded.
2.
Measure the height from the top of the front wheel
opening on the fender to the ground, this is height H1.
