Thank you for choosing Rough Country for all your suspension needs.

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.
Please read instructions before beginning installation. Check the kit hardware against the product layout and kit contents
information on these instructions. Be sure you have all needed parts and know where they go. Also please review tools
needed list and make sure you have needed tools.

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. If question exist we will be happy to answer any questions concerning the de­sign, function, and correct use of our products.

This suspension system was developed using a 31x10.5x15,
tire with factory wheels. If wider tires are used, offset wheels
and trimming will be required. This kit was developed to obtain
a front ride height of 21” on newer body style and 22” older
body style as measured from the center of the front wheel to
the bottom of the fender well. See Photo. It was also intended
to be a leveling kit—taking out the stock factory rake by raising
the rear only 1’ and raising the front 2-3”. If additional rear lift
is desired please contact your Rough Country Distributor.

INSTALLATION INSTRUCTIONS

1. Chock rear wheels where the truck will not roll. Place vehicle in neutral.

2. Raise the front with a floor jack, positioned underneath the front axle cross member. Place jack stands under the

frame rails, behind the front wheel wells and lower frame onto jack stands. Remove the front tires.

3. Mark cam bolts. See Photo 1.

4. The torsion bar keys are removed next and requires the use of a torsion bar tool. Torsion bar tool Part #1067 is

available from Rough Country.

5. Place the torsion bar tool on the cross member and tighten using a 1 1/16 socket until the stock torsion bar threaded
block is free. Make sure the torsion bar tool is properly placed on the torsion bar key to prevent the tool from slipping
and causing possible damage. Be extremely careful when loading or unloading the torsion bars: there is a tremen­dous amount of stored energy in the bars. Be sure to keep your hands and body clear of the adjuster arm assembly
and puller tool in case anything slips or breaks.

6. Remove the stock torsion bar bolt using a 18mm socket and remove the threaded bock. See Photo 2.
