Rough-country 622N2 User Manual download pdf

Thank you for choosing Rough Country for all your suspension needs.

Rough Country recommends a certified technician install this system. In addition to these instructions, professional

knowledge of disassembly and 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 vehi-

cle.

Please read the instructions before beginning the installation. Check the kit hardware against the Kit Contents shown on

page 2. Be sure you have all needed parts and know where they go. If there are any questions about the installation or

installation steps call our tech line at 800-222-7023.

With the installation of all lift kits and larger tires it is important to check the condition of your steering stabilizer. If the

stabilizer is worn or is leaking it should be replaced. Steering stabilizers are designed to restrain “bump steer” and front-

end vibration, giving added life to tires, ball joints, and other steering components. A large bore off-road stabilizer kit is

highly recommended for vehicles equipped with larger tires, please contact your Rough Country distributor for details on

purchasing this Part #87317.

PRODUCT USE INFORMATION

As a general rule, the taller a vehicle is, the easier it will roll. Offset, as much as possible, what is lost in rollover resis-

tance by increasing tire track width. In other words, go "wide" as you go "tall". Many sportsmen remove their mud tires

after hunting season and install ones more appropriate for street driving; always use as wide a tire and wheel combina-

tion as possible to enhance vehicle stability.

Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur. Gener-

ally, braking performance and capability are decreased when significantly 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 al-

tered.

This suspension system was developed using a 35 x12.5 tire on a 15” x 8” wheel with 3.75” of backspacing.

If you have any questions concerning the design, function, and/or correct use of our products please contact one of our

customer service representatives us at 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 oper-

ating the vehicle 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.

IMPORTANT PRE—INSTALLATION INSTRUCTIONS

Prior to beginning this installation it is always good to use a penetrating oil and spray all fasteners that will be removed.

Typically the spring eye bolts and the pitman arm are difficult to remove without having done this step. Rough Country

does offer a replacement spring bolt kit to replace all leaf spring mounting bolts, Part #1184 that is highly recommended

and something that should be considered before proceeding.
