JEEP JK 6” LONGARM
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. Also please review 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. 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 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 re-
sponsible for any product that is altered.
This suspension system was developed using a 37X12.50X17 tire with 4.5” to 4.75” of back spacing on aftermarket
wheels. Stock wheels can be used with this kit with up to a 35x12.5 tire, but different tire manufactures designs may re-
sult in a tire width that could result in contact with the lower control arm and/or front sway bar link in a sharp turn. Please
consult with your tire and wheel expert before purchasing. Also note that if wider tires are desired, offset wheels will be
required.
IMPORTANT NOTE : Upon completing the install of this kit the draglink must be adjusted to center the steer-
ing wheel BEFORE the vehicle is driven. Failure to do so will cause a computer error, odd handling, and
poor performance.
Driveshafts are available from Rough Country. The stock driveshafts do not have enough range of motion,
thus the shaft joints bottom out and damage will occur. It is highly recommended that the stock shafts not
be used and new yoke style shafts are installed.
2012 and newer JK will need exhaust modifications. An aftermarket 180 degree exhaust pipe is required.
If question exist we will be happy to answer any questions concerning the design, function, and correct use of our prod-
ucts by calling 1-800-222-7023
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
the windshield or on the vehicle’s dash. The decal should act as a constant reminder for whoever is operating the vehi-
cle of its unique handling characteristics.
INSTALLING DEALER - it is your responsibility to install the warning decal and forward these installation instructions on
to the vehicle owner for review. These instructions should be kept in the vehicle for its service life.
