PRODUCT USE INFORMATION
⚠ WARNING 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. This suspension system was developed using a 285/65/R18, tire with factory 18″ wheels. Note: If wider tires are used, offset wheels will be required and trimming will be required.
⚠ NOTICE If equipped 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. If you have any questions concerning the design, function, and correct use of our products please contact us at 800-2227023.

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 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.
