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

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.
Post suspension system vehicles may experience drive line vibrations. Angles may require tuning, slider on shaft may
require replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced
The 4” suspension system was developed for 33x12.50x15 tire on an after market wheel with 3.75” of back spacing,
on an 8” wide wheel. Due to the inconsistency of vehicles when manufactured and the various options available, the
amount of actual lift gained by this lift kit will vary. On models outfitted with extra bolt-on equipment and accessories,
Rough Country offers new coil spring isolator pads made from polyurethane to boost ride height 3/4". These are
available for the front or rear.
With the installation of this kit and larger tires it is highly recommended that an aftermarket stabilizer be added.
