IMPORTANT INFORMATION THAT NEEDS TO BE
READ BEFORE INSTALLATION BEGINS:
Tuff Country EZ-Ride Suspension recommends using
a 4.5” back spacing on the tire and wheel
combination. The stock wheels will not work in
combination with the new spindle design.
Before installation begins, Tuff Country EZ-Ride
Suspension highly recommends that the installer
performs a test drive on the vehicle. During the test
drive, check to see if there are any uncommon
sounds or vibrations. If uncommon sounds or
vibrations occur on the test drive, uncommon
sounds or vibrations will be enhanced once the
suspension system has been installed. Tuff Country
EZ-Ride Suspension highly recommends notifying
the customer prior to installation to inform the
customer of these issues if they exist.
General Motors has introduced a new transfer case
option that uses the name “Auto Trac”. Auto Trac is a
full time 4WD system. This options pertains to the
Tahoe (2 or 4 door), Suburban and some pick up
trucks. To identify this, see the transfer case
selection panel located on the dash board. Below the
2HI button it will read “Auto 4WD” or “Auto”.
Vehicles with the “Auto Trac” transfer case may
encounter a front drive line vibration when the lift kit
is installed. After installation, if the vehicle that you
are working on encounters any front driveline
vibration, the stock driveline may need to be
replaced. If this is the case on the vehicle that you
are working on, please feel free to contact Tuff
Country or your local Tuff Country dealer and order
part # 10820 to replace your stock driveline.
Tuff Country EZ-Ride Suspension highly
recommends NOT installing part # 14810 on vehicle’s
with a two piece rear driveline. If this suspension
system is installed on vehicle’s with a two piece rear
drive line, rear drive line problems may occur and
your Tuff Country WARRANTY WILL BE VOID.
New longer front and rear shocks are needed after
this suspension system has been installed and the
front and rear shocks need to be ordered as a
separate part #. If you have not already ordered your
front and rear shocks, please feel free to contact Tuff
Country or your local Tuff Country dealer and order
your front and rear shocks.
After the completion of the installation a front end
alignment is required. Also an exhaust modification
is needed.

feel free to call one of our customer service
representatives @ (801) 280-2777.
Special Post Installation Procedure: Tuff Country EZRide Suspension highly recommends adding a
minimum of 1 pint, but no more that 1 1/2 pints, of
proper front differential fluid into the front
differential. To achieve this, you may have to fill the
differential with it on its side or you may have to
insert the fluid through the vend tube opening. On
occasion, the customer may find burping of fluid
coming out of the front vent tube.
Please Follow Instructions Carefully:
Before installation begins, measure from the center
of the hub, to the bottom of the fender well, and
record measurements below.
Pre-Installation Measurements:

Please follow instructions carefully:
Front End Installation:
1. To begin installation, block the rear tires of the vehicle
so that the vehicle is stable and can’t roll backwards.
Safely lift the front of the vehicle, and support the frame
with a pair of jack stands. Place a jack stand on both the
driver and passenger side. Next, remove the tires and
wheels from both sides.
2. Working on the driver side, remove the stock inner
rubber fender splash guard and save the stock inner
rubber fender splash guard and hardware for later reinstallation. Repeat procedure on passenger side.
3. Working on the driver side, remove the stock shock
from the stock upper and lower location and save the
stock hardware for later re-installation. Longer shocks are
needed, so the stock shocks may be discarded.
Special
Note: Shocks are not included with this suspension
system and need to be ordered as a separate part

not to rip or tear the stock outer tie rod ball joint dust
boot. Once you have broke the stock taper, remove the
nut and set a side for later re-installation. Remove the
stock outer tie rod from the stock steering knuckle and let
hang.
14. Working on the driver side, remove the (2) stock bolts
that connect the stock brake caliper to the stock rotor.
Save the stock hardware for later re-installation. Using a
