JEEP JK 4” SUSPENSION KIT

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. 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 re-

sponsible for any product that is altered.

This suspension system was developed using a 35X12.50X17 tire with 4.5” to 4.75” of back spacing on aftermarket

wheels. Stock wheels can be used with this kit with up to a 35x12.5 tire, but different tire manufactures designs may re-

sult in a tire width that could result in contact with the lower control arm and/or front sway bar link in a sharp turn. Please

consult with your tire and wheel expert before purchasing. Also note that if wider tires are desired, offset wheels will be

required. If question exist we will be happy to answer any questions concerning the design, function, and correct use of

our products by calling 1-800-222-7023.

IMPORTANT NOTES : Upon completing the install of this kit the draglink must be adjusted to center the steering

wheel BEFORE

the vehicle is driven. Failure to do so will cause a computer error, odd handling, and poor per-

formance.

On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate

factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission

pan tearing the factory boot and rubbing on the shaft. Generally this occurs during heavy articulation when

front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper pro-

cedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase

clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed.

Additionally on 2012 Models, additional exhaust modification on the passenger side crossover pipe will

be required for adequate clearance on the front driveshaft.

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 operating the vehi-

cle of its unique handling characteristics.
