CAUTION
CAUTION
Do not loosen or remove any part of the hitch except the L‑pins and L‑pin
clips while the hitch is under load.
Always secure tow vehicle and trailer with parking brake and wheel chocks
before setting up or adjusting hitch.
Disengage weight distribution before towing or backing the trailer where
there is a signicant transition in grade which puts excessive strain on the
hitch, i.e. a at street to a steep uphill driveway.
Important Hitch Information
Weight Distribution:
Weight distribution is the ability of a hitch to transfer some of the tongue
weight of the trailer ahead to the tow vehicle axles, and backward to the
trailer axles. Without weight distribution the tow vehicle “teeter-totters” on
the rear axle of the tow vehicle, and unweights the front axle. Proper weight
distribution transfers weight back to the front steering axle, forcing it back to
the ground.
Proper weight distribution also adds performance to the built-in sway control
feature of your e2™ hitch. e e2 hitch requires a minimum tongue weight of
at least 10% of the gross trailer weight. is tongue weight gets distributed,
and helps generate the friction needed to reduce trailer sway.
Sway Control:
Sway control is a built-in, premium feature of your e2 hitch. Unlike
conventional chain style weight distribution hitches, e2 hitches have Built-in
Sway Control™ features. You do not need to purchase, install, store, or hook up
any additional hardware to get the benets of this sway control. You can back
up without disengaging the hitch. Once the spring arms are tensioned, the
Built-in Sway Control is in force.
Built-in Sway Control on the e2 hitch works through the connection
between your spring arms and L-brackets. e force required by the hitch to
distribute weight rests on the L-brackets through the spring arms. e e2 hitch
takes advantage of the steel-on-steel friction generated at these points to help
reduce trailer sway.
is added friction makes it much more dicult for the trailer to sway
side-to-side while its being towed, as sometimes happens when you encounter
things like a gust of wind or passing semi-truck. When set up well and properly
