PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Seat
belts and shoulder harnesses should be worn at all times. Avoid situations
where a side rollover may occur.
Generally, braking performance and capability are decreased when
larger/heavier tires and wheels are used. Take this into consideration while
driving. Do not add, alter, or fabricate any factory or after-market parts to
increase vehicle height over the intended height of the Rough Country product
purchased. Mixing component brands is not recommended. Rough Country makes no
claims regarding lifting devices and excludes any and all implied claims. We
will not be responsible for any product that is altered. If questions exist we
will be happy to answer any questions concerning the de-sign, function, and
correct use of our products.
This suspension system was developed using a 34” or 295/70R18-295/60R20, tire
on 9” wheels with a +12 offset. Factory wheels and tires can be used. If using
a larger tire on the factory wheel, wheel spacers are required. Note if wider
tires are used, offset wheels will be required and trimming will be required.
This vehicle will require the EPAS (Electronic Power Assist Steering) plugs to
be disconnected prior to beginning installation of this kit. See installation
instructions. Failure to disconnect these plugs may result in damage to the
EPAS module resulting in an error message being displayed, which will require
replacement of the EPAS module.
DEALER AND VEHICLE OWNER
Any vehicle equipped with any Rough Country product should have a “Warning to
Driver” decal installed on the inside of the windshield or on the vehicle’s
dash. The decal should act as a constant reminder for whoever is operating the
vehicle of its unique handling characteristics.
INSTALLING DEALER – it is your responsibility to install the warning decal and forward these installation instructions on to the vehicle owner for review. These instructions should be kept in the vehicle for its service life.
Note to installer : Before installation begins we recommend that a test drive be performed. While driving check for uncommon sounds and/or vibrations . What you feel and hear during the test drive will only magnify once lift kit is installed. Advise you to discuss possible issues identified from drive with customer before proceeding to install this kit.
