Thank you for choosing Rough Country for your suspension needs.
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.
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".
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 or 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 product that
is altered. Braking performance and capability are decreased when significantly larger/heavier tires and wheels are used.
Take this into consideration while driving.
The required installation time for this system is approximately 2 hours. This suspension system was developed using a
30” X 9.50 or equivalent tire on an 16” wheel. Before installing other combinations, please consult your local tire and
wheel specialist.
If questions exist on the design, function, and correct use of our products please contact us at 800-222-7023.
NOTICE TO DEALER AND VEHICLE OWNER
Any vehicle equipped with any Rough Country product should have a “Warning to Driver” decal installed on the inside of
