07-UP TAHOE/YUKON/SUB 5” KIT
Thank you for choosing Rough Country for your suspension needs. We appreciate your business!!
This kit will not fit vehicles equipped with electric steering or trucks with factory auto leveling or auto ride systems.
Important note: Please refer to the instructions on the last page for trimming the tie rods. For alignment purposes, it will be necessary to trim/shorten the tie rod end to allow the front end alignment to be set properly.
Rough Country recommends a certified technician install this system. In addition to these instructions, professional knowl­edge of disassemble/reassembly procedures as well as post installation checks must be known. Attempts to install this sys­tem without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle.
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 responsi­ble for any product that is altered. We will be happy to answer any questions concerning the design, function, and correct use of our products.
This kit is packaged as a leveling kit—raising the front 5” and the rear 4.5”.
Due to differences in manufacturing, dimension and inflated measurements, tire and wheel combinations should be test fit prior to installation. For this application we recommend a 18” or larger wheel not to exceed 9” in width. When using a 18” wheel backspacing should be maximum of 5.5” and a minimum 5.0” . With a 20” or larger wheel backspacing should be a maximum of 6.0” and a min of 5.5”. Additionally a quality tire of radial design is recommended, not exceeding 33” tall and
12.5” wide. Please note that use of a 33” x 12.5” tire may require modification to the front valance.
Optional kicker Bars Part #1262 are available for this kit. Please contact you local Rough Country Dealer for infor­mation.
INSTALLING DEALER - it is your responsibility to install the warning decal and forward these installation instructions on to the vehicle owner for review. These instructions should be kept in the vehicle for its service life.
We hope installing your Rough Country lift kit is a positive experience. Please note that variations in construction and assembly in the vehicle manufacturing process will virtually ensure that some parts may seem difficult to install. Addi­tionally, the current trend in manufacturing of vehicles re­sults in a frame that is highly flexible and may shift slightly on disassembly prior to installation. The use of pry bars and tapered punches for alignment is considered normal and usually does not indicate a faulty product. However, if you are uncertain about some aspect of the installation process, please feel free to call our tech support department at 800­222-7023. We do not recommend that you modify the Rough Country parts in any way as this will void any warranty ex­pressed or implied.
