07 TOYOTA FJ CRUISER 6” SUSPENSION
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 parts list. Be
sure you have all the needed parts and understand where they go. 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 35x12.50x17 tire on an after market wheel with 4.5/8” of back spacing,
on an 8” wide wheel. Clearancing the body mount is required. Failure to clearance mount could result in tire and body
damage. See body mount section.
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
characteristics. INSTALLING DEALER—It is your responsibility to install the warning decal and to forward these inKit Contents
