all the brake line and ABS points, make sure not to over
extend or kink any brake lines or ABS lines.
97. Working on the driver side and using a pair of “C” chan-
nel vise grips, clamp the stock rear springs together. Place
one towards the front of the stock centering bolt and one
towards the rear. Special note: Make sure not to clamp
the stock over load.
98. Carefully remove the stock centering bolt from the stock
location and discard. There is a dahl that is holding the stock
over load to the stock spring pack. This dahl needs to be
removed. To do this, remove the stock over load from the
stock spring pack and remove the dahl. The dahl maybe dis-
carded. Set the stock over load aside.
99. Locate the new rear add-a-leafs. Also, locate the new
3/8” centering bolts and nuts from hardware bag CB38.
Working on the driver side, install the new add-a-leaf
between the stock spring and the stock overload. Secure
using the new 3/8” centering bolt and nuts. Tighten the new
centering bolt until all the springs come together and torque
to 40 ft lbs. Special note: Make sure that the hole where
the dahl was located is installed towards the rear of the
vehicle. Also, Tuff Country does not recommend using a
high speed air gun to tighten the nut all the way down.
Once the springs are starting to come together, Tuff
Country recommends using a hand wrench to finish
tightening the nut. If a high speed air gun is used to
tighten the centering bolt all the way down, the center-
ing bolt may strip causing the springs to come apart. By
installing some anti-cease lubricant on the new center-
ing bolt will also help during the installation of the new
rear add-a-leaf. Remove the “C” channel vise grips that are
holding the stock spring together.
100. Working on the driver side and using a die grinder, care-
fully cut off the excess thread from the new centering bolt.
101. Locate (1) new rear block. Working on the driver side,
install the new block between the modified stock spring pack
and the stock axle. Special note: There is an arrow
stamped in the new block, make sure that this arrow is
pointing towards the front of the vehicle. Also, make
sure that we install the block into the center hole in the
stock spring perch. Carefully raise up on the hydraulic floor
jack until the new block seats properly with the modified
stock spring pack.
102. Locate the (2) new 9/16” x 2 9/16” x 11 5/8” square u-
bolts. Locate (4) 9/16” u-bolt high nuts and (4) 9/16” u-bolt
washers from hardware bag 916NW. Also, locate the stock
upper bump stop plate and stock lower u-bolt plate. Working
on the driver side, install the new u-bolts into the stock loca-
tion and secure using the new the new hardware. For now,
just get the new hardware started on each leg of the new u-
bolts.
103. Repeat step # 96 - 102 on the passenger side.
104. Move back to the driver and passenger side and torque
the new u-bolts to 115 ft lbs.
105. Locate (2) rear brake line relocation bracket from hard-
ware bag 56070NB1. Also, locate the stock e-brake cable
hardware that was removed earlier. Working on the driver
side, install the new brake line relocation bracket to the stock
rear axle using the stock hardware. Do not tighten at this
point. Repat procedure on the passenger side.
106. Locate (2) 5/16” x 1” bolt, (4) 1/4” USS flat washers and
(2) 5/16” unitorque nuts from hardware bag # 1 from hard-
ware box 56070NB. Working on the driver side, install the
stock e-brake cable bracket to the newly installed brake line
relocation bracket and secure using the new 5/16” x 1” bolts
and hardware. Make sure to use thread locker or loctite and
torque to 12 ft lbs. Now move back to the stock lower e-
brake mounting hardware and add some thread locker or
loctite and torque to 10 ft lbs. Repeat procedure on the pas-
senger side.
107. Locate the new rear shocks. Special note: New longer
rear shocks are needed, if you have not already ordered
your new shocks, please contact Tuff Country or your
local Tuff Country dealer and order the proper shocks.
Tuff Country recommends using a 30” fully extended
nitrogen gas shock. Insert the proper crush sleeve from
your shock sleeve bag into the eyelet of the new shocks.
Special note: make sure to use a lithium or moly base
grease to apply on the sleeve before it is installed into
the new shock. Now install new shocks into the stock loca-
tion using the stock hardware for the lower mount and the
new upper bushing, washers, and nut on the upper mount.
Make sure to add thread locker or loctite and torque the bot-
tom hardware to 65 ft lbs. and the upper to 18 ft lbs.
