passenger side..
18. Locate (2) new S10051, (2) 1/2” x 6” bolts and (2) 1/2”
unitorque nuts from hardware bag 52907NB1. Also, locate
the stock oversize washers that were removed earlier in the
installation. Carefully lower down on both hydraulic floor
jacks allowing enough room for the new front differential
spacers to be installed. Working on the driver side, install the
new front differential spacer between the front differential
brackets and the stock front cross member and secure using
the new 1/2” x 6” bolt, 1/2” unitorque nut and the stock over
size washer. Do not tighten at this point. Repeat proce-
dure on the passenger side. Move back to the 1/2” x 6”
bolt on the driver and passenger side and add some
thread locker or loctite and torque to 80 ft lbs. Carefully
remove both hydraulic floor jacks front under the front differ-
ential.
19. Locate (2) S10090 sleeves, (2) 8 mm x 35 mm bolts and
(2) 8 mm” USS flat washers from hardware bag 52907NB1.
Also, locate the stock skid plate and the stock skid plate
hardware. Re-install the stock skid plate into the stock upper
location using the stock hardware. Do not tighten at this
point. Secure the lower portion of the skid plate to the stock
location using the new 8 mm x 35 mm bolts, 8 mm USS flat
washers and make sure to install the new spacer between
the stock skid plate and the stock location. Torque the new 8
mm x 35 mm bolt and stock hardware to 12 ft lbs.
20. Re-install the tires and wheels and torque the lug nuts to
the proper torque specifications. Carefully lower the vehicle
to the ground.
Front installation complete!
Rear end installation:
21. To begin installation, block the front tires of the vehicle so
that the vehicle is stable and can’t roll forward. Safely lift the
rear of the vehicle and support the frame with a pair of jack
stands. Place the jack stands on both the driver and the pas-
senger side. Make sure that the parking brake is not set.
Next, remove the tires and wheels from both sides.
22. Working on the driver side, remove the shock from the
upper and lower location. Set the shock and the stock hard-
ware aside for later re-installation. New longer rear shocks
are not required but highly recommended once part #
52907 has been installed on your vehicle and the rear
shocks need to be ordered as a separate part #. If you
have not already ordered your rear shocks, please feel
free to contact Tuff Country or your local Tuff Country
dealer and order your rear shocks. Tuff Country recom-
mends installing a 26” fully extended shock in the rear.
Repeat procedure on the passenger side.
23. Working on the driver side, remove the stock brake line
bracket from the driver side of the rear axle. The stock bolt
may be discarded.
24. Position a pair of hydraulic floor jacks under the rear dif-
ferential. Place one jack stand on the driver side and one on
the passenger side. Raise up on both hydraulic floor jacks at
the same time until they make contact with the rear differen-
tial. Working on the driver side, remove the rear u-bolts. The
rear u-bolts and the u-bolt nuts may be discarded, save the
u-bolt washers. Place the u-bolt plate and the bump stop
aside for later re-installation. Repeat procedure on the pas-
senger side.
25. Carefully lower down on both hydraulic floor jacks at the
same time until the stock rear spring assembly separates
from the rear axle to allow enough room for the new rear
add-a-leaf to be installed.
26. Working on the driver side, place a pair of “C” clamp vise
grips on each side of the centering bolt. Carefully remove the
centering bolt and nut and discard. Carefully remove the “C”
clamp vise grips that are holding the springs together.
Special note: Be careful when removing the “C” clamps,
the springs are under tension and can be dangerous.
Repeat procedure on passenger side.
27. Locate (2) new rear add-a-leafs. Locate (2) 3/8” center-
ing bolts and (2) 3/8” fine nut from hardware bag CB38.
Install the new rear add-a-leaf into the spring assembly.
Secure the new rear add-a-leaf to the spring assembly using
the new 3/8” center bolt and nut. Torque to 28 ft. lbs.
Special note: If the new add-a-leaf that you are installing
into the stock spring assembly has an offset center hole
location, place the longest side of the add-a-leaf
towards the rear of the vehicle. Also the new add-a-leaf
should be installed into the stock spring assembly in
progression in order, from longest to shortest. The new
add-a-leaf should be installed between the stock over-
load and the stock spring pack. The stock overload is
usually the un-arched spring at the bottom of the stock
leaf pack. Also, Tuff Country EZ-Ride Suspension rec-
ommends not using any air tools when installing the
new add-a-leafs into the stock spring assembly. If air
tools are used the centering bolt may strip, causing the
