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 the
passenger side. Next, remove the front wheels and tires
from both sides.
2. Working on the front of the vehicle, remove the stock
upper front skid plate from the stock location. Save the
stock upper skid plate and the hardware for later re-instal-
lation.
3. Place the stock upper front skid plate on a work bench
with the “H3” logo facing upwards. Working on the driver
side lower corner, measure 1 1/2” from the side edge of the
skid plate towards the center and scribe a mark. Next,
measure 2 1/4” from the bottom edge of the skid plate
towards the center and scribe a mark.
4. Working on the passenger side lower corner, measure 1
1/2” from the side edge of the skid plate towards the center
and scribe a mark. Next, measure 3 1/4” from the bottom
edge of the skid plate towards the center and scribe a
mark.
5. Using a die grinder, carefully cut out each corner of the
stock skid plate where the marks were scribed in steps 3

7. Working on the driver side, remove the stock shock from
the stock location. The stock shock and stock upper mount-
ing hardware may be discarded. Save the stock lower
mounting hardware for later re-installation. Special note:
New longer front shocks are needed after this
suspension system has been installed and the front
shocks need to be ordered as a separate part #. If you
have not already ordered your front shocks, please feel
free to contact Tuff Country or your local Tuff Country
dealer and order your front shocks. Tuff Country
recommends installing a 20” fully extended nitrogen
gas shock in the front. Repeat procedure on the
passenger side.
8. Working on the driver side, remove the torsion bar
adjusting bolt and torsion bar key and set aside for later
re-installation. Special note: Mark both torsion bars
before removal so that they can be re-installed back
into the same location. Example: Driver vs. Passenger
and front vs. rear. Remove the stock torsion bar from the
stock location and set aside for later re-installation. Repeat
procedure on the passenger side.
9. Working on the driver side, remove the stock front sway
bar end link from the stock location. The stock sway bar
end link may be discarded. Repeat procedure on the
passenger side.

outer tie rod ball joint and remove the stock outer tie rod
from the stock knuckle. Special note: Take special care
not to rip of tear the stock outer tie rod ball joint dust
boot.

quick disconnect located above the stock upper control
arm. Disconnect the ABS lines from each other. Also,
disconnect the stock ABS line from any other mounting
points. Also, at this time, remove the stock brake line
bracket that attaches to the stock upper control arm. Save
the stock hardware for later re-installation.
12. Working on the driver side, remove the (2) stock bolts
that connect the stock brake caliper to the stock knuckle.
