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.
Braking performance and capabilities are decreased when significantly larger/heaver tires and wheels are used. Take
this into consideration while driving. Also, speedometer recalibration is necessary when larger tires are installed.
Do not add, alter, or fabricate any factory or after-market parts which increase vehicle height over the intended height of
the Rough Country product purchased. Mixing component brands, lifts, and/or combining body lift with suspension lifts
voids all warranties. 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.
This kit is packaged as a leveling kit. If you desire a different look or if your truck has a tool box or something else that is
going to bring the rear end down, please consult with your sales person about higher block and u-bolt options. If your
vehicle is equipped with a rear sway bar (Tahoe and Suburban standard equipment), we recommend that you
purchase longer sway bar links, part # 1038. Steering Stabilizer Part # 87369 is also available from Rough Coun-
try for use with this kit.
Important Note: 4 Door Tahoe’s and Yukon’s require part number 89501 torsion bar cross member bracket in
addition to the standard kit to complete installation, if you have not ordered/received 89501 – Torsion Bar Kit,
then please call your Rough Country distributor before you begin installation.
