PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. We strongly recommend, because of rollover possibility that
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 them concerning the design, func-
tion, and correct use of our products.
This suspension system was developed using a 35X12.50/17, tire on aftermarket 17” wheels with 4 1/2-5” backspace.
The lift was designed to lift the front 6” and the rear 5-5 1/2” to level the vehicle. Due to manufacturing, dimension vari-
ances, and inflation all tire and wheel combinations should be tested prior to installation on all oversized / wider then
stock tires We recommend a wheel not exceeding 8" in width be used with a minimum backspacing of 4.5" to a maxi-
mum of 5".
Rough Country recommends not operating the vehicle in 4 wheel drive above 40 mph. Doing so may result in a
low frequency front driveshaft vibration. See Driveshaft Re-clocking Instructions.
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.
