vehicle.
Please read all the instructions before beginning the installation. Check the kit hardware against the kit contents. Be

PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend seat belts and shoulder
harnesses should be worn at all times. Avoid situations where a side rollover may occur.
Braking performance and capabilities are decreased when significantly larger/heaver tires and wheels are used. Take
this into consideration while driving. Also, speedometer recalibration is necessary when larger tires are installed.
Do not add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height
of the Rough Country product purchased. Mixing component brands, lifts, voids all warranties. Rough Country makes
no claims regarding lifting devices and excludes any and all implied claims. We will not be responsible for any prod-
uct that is altered.
Post suspension system vehicles may experience drive line vibrations. Angles may require tuning and U-joints may
need to be replaced
The 2 1/2” long arm suspension system was developed for 33x12.50x15 tire on an after market 8” wide wheel
with 3.75” of back spacing. A 35x12.50x15 tire on an after market 8” wide wheel with 3.75” of back spacing
can be used, but only if high fender clearance kits are installed.
Due to the inconsistency of vehicles when manufactured and the various options available, the amount of
actual lift gained by this lift kit will vary. On models outfitted with extra bolt-on equipment and accessories,
Rough Country offers new coil spring isolator pads made from polyurethane to boost ride height 3/4". These
are available for the front or rear.
• With the installation of this kit and larger tires it is highly recommended that an aftermarket stabilizer(s) be added.
• Additionally, the exhaust system must be modified by an exhaust specialist to clear all components.
• On Rubicon models the air compressor for the air lockers on the frame by the rear of the skid plate will have to be
relocated. Refer to installation instructions for detail.
NOTICE TO DEALER AND VECHICLE OWNER
Any vehicle equipped with any Rough country product must have the “Warning to Driver” decal installed on the sun
visor or dash. The decal is to 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 to forward these in-
stallation instructions on to the vehicle owner for review and to be kept in the vehicle for its service life.
We hope installing your Rough Country lift kit is a positive experience. Please note that variations in con-
struction and assembly in the vehicle manufacturing process will virtually ensure that some parts may seem
difficult to install. The use of pry bars and tapered punches for alignment is considered normal and usually
does not indicate a faulty product. However, if you are uncertain about some aspect of the installation proc-
ess, please feel free to call our tech support department at 800-222-7023. We do not recommend that you
modify the Rough Country parts in any way as this will void any warranty expressed or implied.
