Page 1
Rough Country recommends this system be installed by a certified technician. 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 instructions before beginning installation. Check the kit hardware against the parts list. Be sure you
have all needed parts and know where they go.
With the installation of all lift kits and larger tires it is important to check the condition of your steering stabilizer. If
the stabilizer is worn or is leaking it should be replaced. Steering stabilizers are designed to restrain “bump
steering” and front end vibration, giving added life to tires, ball joints, and other steering components. A multiple
stabilizer kit is recommended for vehicles equipped with a snow plow, winch, or larger tires
PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Offset, as much as possible, what is lost in rollover
resistance by increasing tire track width. In other words, go "wide" as you go "tall". Many sportsmen remove their
mud tires after hunting season and install ones more appropriate for street driving; always use as wide a tire and
wheel combination as possible to enhance vehicle stability.
We strongly recommend, because of rollover possibility, that the vehicle be equipped with a functional roll-bar and
cage system. 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 significantly 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 question exist we will be happy to answer any questions concerning the design, function, and correct use of our
products.
