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.

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.
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 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 3” suspension system was developed for 35x12.50x17 tire on an 8” wheel.
This 3” system comes standard with a 2” block and u-bolt set-up for the rear to give the truck a level look. Personal pref-
erence, OE options, and aftermarket add-ons may require additional lifting options. One option on the SD is factory
contact overload springs (a set of springs that sit above the leaf springs and that under load come in contact
with two stops off of the frame) Vehicles equipped with factory contact overloads require the longer u-bolt also
included in this kit. On vehicles with dual rear wheels the use of blocks and longer u-bolts is not recommended
and should not be installed.

INSTALLING DEALER—It is your responsibility to install the warning decal and to forward these installation
instructions on too the vehicle owner for review and to be kept in the vehicle for its service life.
