06-UP JEEP COMMANDER 2” LIFT KIT

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 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 this page. 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.

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 questions exist we will be happy to answer any questions concerning the design, function, and correct use of our prod­ucts.

This suspension system was developed using a 265/70R-17 tire with factory wheels. Note if wider tires are used, offset
wheels will be required and trimming will be required.
