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.
Due to inconsistency of vehicles when manufactures and various options available, the amount of actual lift gained by
this lift kit could vary.
This suspension system was developed using a 31 x 10.50 x 15 tire with factory wheels. After market wheel will fit with 3
5/8” back spacing. Larger tire and wheel combinations may increase leverage on suspension, steering and related com-
ponents. Consider the additional stress you could be adding on the OE components, when selecting combinations larger
than OE.
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.
