Thank you for choosing Rough Country for all of your suspension needs.

Rough Country recommends a certified technician installs this system. In addition to these instructions, professional

knowledge of disassemble/reassembly procedures as well as post installation checks must be known. Attempts to install

this system without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle.

Please read all the instructions before beginning the installation. Check the kit hardware against the Kit Contents list on

next page. Be sure you have all the needed parts and understand where they go. Also please review the tools needed

list to be certain that you have the tools necessary to complete the installation.

PRODUCT USE INFORMATION

As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend, because of rollover possibility, that

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/heavier tires and wheels are used. Take this into

consideration while driving. Also, speedometer recalibration is necessary when larger tires are installed.

Do no 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, with this suspension lifts voids all warranties.

Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re-

sponsible for any product that is altered.

Due to differences in manufacturing, dimension and inflated measurements, tire and wheel combinations should be test

fit prior to installation. For this application we recommend a wheel not to exceed 9” in width with 4.5 “ of backspacing..

Additionally a quality tire of radial design is recommended, not exceeding 35” tall and 12.5” wide. If this vehicle was

equipped from the factory with 17” wheels and if purchasing new wheels, the wheel size must not be below 17” but can

be larger than 17” due to the vehicle being equipped with larger calipers /rotor.

NOTICE TO DEALER AND VEHICLE 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 character-

istics. INSTALLING DEALER—It is your responsibility to install the warning decal and to forward these installation in-

structions on too 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 construc-

tion and assembly in the vehicle manufacturing process will virtually ensure that some parts may seem difficult

to install. Additionally, the current trend in manufacturing of vehicles results in a frame that is highly flexible

and may shift slightly on disassembly prior to installation. The use of pry bars and tapered punches for align-

ment is considered normal and usually does not indicate a faulty product. However, if you are uncertain about

some aspect of the installation process, 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 ex-

pressed or implied.

Thank you for choosing Rough Country for all of your suspension needs.
