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 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 33x11.50-R20 tire on 20x8.5” wheels with 5.75” backspacing. Note if wider tires are used, offset wheels will be required and trimming will be required.
