Thank you for choosing Rough Country for your suspension needs.
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 on the rear cover of these instructions. 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 responsible for any product that is
altered. If question exist we will be happy to answer any questions concerning
the design, function, and correct use of our products.
The electric power steering must be unplugged before any of the steering
components are removed. Failure to do so may cause damage to the electric
power steering.
Trucks equipped with a mass damper on the front diff, the damper will have to
be removed.
This kit is packaged as a leveling kit—raising the front 3.5” and the back
2.5”. If you desire a different look or if the vehicle has a tool box or added
weight in the rear, please consult with your sales representative about other
block and u -bolt options.
This suspension system was developed using a 295/60R20 tire on the factory 20”
wheel. If wider tires are used trimming may be required. Due to manufacturing,
dimension variances, and inflation, all tire and wheel combinations should be
tested prior to installation on all oversized / wider then stock tires and
wheels.
Fits crew cab short bed models only. Will not fit models with adaptive ride
control and will not fit GMC AT4 or Chevy Trail Boss models.
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
vehicle.

POST INSTALLATION INSTRUCTIONS
-
Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed, and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring har- ness. Check steering gear for clearance. Test and inspect brake system.
-
Perform steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile or heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/ replacement may result in component failure.
-
On some vehicles the front lower skirting will need to be trimmed if using certain wheel /tire combinations and with heavy offset wheels. Trim only as needed.
-
Activate four wheel drive system and check front hubs for engagement.

Toe In in degrees 0.1 +-.2 -
Perform head light check and adjustment to proper settings.
