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.
If questions exist we will be happy to answer any questions concerning the design, function, and correct use of our prod-
ucts.
This suspension system was developed using a Maximum tire size of 33 X 12.5 tires with an 17 x 8 wide aftermarket
wheel with 4 5/8” backspacing.
