Thank you for choosing Rough Country for 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. Be
sure you have all the needed parts and understand where they go. If questions exist please call 1-800-222-7023. Also
please review the tools needed list and make sure you have needed tools.
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
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.
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 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, and/or combining body lift with suspension 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.
The 6” suspension system was developed for Maximum tire size of 35x12.50x17 on an after market wheel with 4.5/8” of
back spacing and 8” wide wheel. Clearancing the body mount is required. Failure to clearance mount could result in
tire and body damage. See body mount section.
A helpful tip is to leave all fasteners loose until the installation of all components is completed. This will allow the brack-
ets to line up without using force. At that time tighten all fasteners to specs.
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 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.
