Tuff Country 24810 - Ford 80-96 F150 4 Lift Kit - Manual (Page 11)

Rear end installation:
42. To begin installation, carefully block the front tires and
wheels so that the vehicle can not roll forward. Safely lift the
rear of the vehicle and support the vehicle with a pair of jack
stands. Place a jack stand on both the driver and the pas-
senger side. Next, remove the rear wheels and tires from
both sides.
43. Working on the driver side, remove the stock shock from
the stock location. The stock shock may be discarded but
save the stock upper and lower hardware. Repeat procedure
on the passenger side. New longer rear shocks are need-
ed after this suspension system has been installed 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
recommends installing a 26” fully extended nitrogen gas
shock in the rear.
44. Working on the driver side, remove the stock sway bar
end link from the stock sway bar. Save the stock hardware.
Repeat procedure on the passenger side.
45. Place a pair of hydraulic floor jacks under the rear differ-
ential. Carefully raise up on the hydraulic floor jacks until
they make contact with the rear differential.
46. Working on the driver side, remove the stock u-bolts from
the stock location. The stock u-bolts and hardware may be
discarded. Save the stock upper u-bolt plate. Repeat proce-
dure on the passenger side.
47. Carefully lower down on both hydraulic floor jacks at the
same time allowing enough room for the new rear add-a-
leafs to be installed. Working on the driver side, remove the
stock block from the stock location and set aside. Repeat
procedure on the passenger side.
48. 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. Repeat procedure on the passenger
side.
49. Carefully remove the stock centering bolt from the stock
location and discard. Special note: Once the stock cen-
tering bolt has been removed, the stock over load will
fall out. Save the stock over load. Repeat procedure on
the passenger side.
50. 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: Tuff Country does not recom-
mend using an 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 an air gun is used to tighten the
centering bolt all the way down, the centering bolt may
strip causing the springs to come apart. Repeat proce-
dure on the passenger side.
