Rough Country recommends a certified technician installs this system. In addition to these instructions, profes-
sional knowledge of disassemble/reassembly procedures as well as post installation checks must be known. At-
tempts to install this system without this knowledge and expertise may jeopardize the integrity and/or operating
safety of the vehicle.

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 possi-
bility, 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 in-
stalled.
Do not 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.
This kit is packaged as a leveling kit—raising the front 4” and the back 2” or raising the front 6” and the back 4”. If
you desire a different look or if your truck has a tool box or something else that is going to bring the rear end
down, please consult with your sales repetitive about option higher block and u-bolt options or the use of an add-
a-leaf.
The 4” suspension system was developed for 35x12.50x17 tire on an after market wheel with 4.5” of back spac-
ing. The 6” suspension system was developed for 37x13.50x17 tire on an after market wheel with 4.5” of back
spacing.
