Thank you for choosing Rough Country for all your suspension needs.
PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Offset, as much as possible, what is lost in rollover resistance by increasing tire track width. In other words, go "wide" as you go "tall". Many sportsmen remove their mud tires
after hunting season and install ones more appropriate for street driving; always use as wide a tire and wh eel combination as possible to enhance vehicle stability.
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 significantly larger/heavie r 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 recom mended.
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 concerning the design, function, and correct use of our products we will be happy to answer these
questions.
