202 STARTING AND OPERATING
Weight-Distributing Hitch
A weight-distributing hitch 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 consistent steering and brake
control, thereby enhancing towing safety.
The addition of a friction/hydraulic sway control
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.
Weight distributing systems may not be

compatible with surge brake couplers.
Consult with your hitch and trailer manufac-
turer or a reputable Recreational Vehicle
dealer for additional information.
