Rough Country 7500 - Manual

Page 1
Rough Country recommends a certified technician install 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 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 consider the installation of a steering stabilizer. Steering
stabilizers are designed to restrain “bump steering” and front end vibration, giving added life to tires, ball joints, and other
steering components.
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".
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.

unique handling characteristics.
INSTALLING DEALER - it is your responsibility to install the warning decal and forward these installation instructions on to the
