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 driver side, remove the shock from the
upper and lower location. Save the lower hardware, The
upper nuts and shock may be discarded. Repeat procedure
on the passenger side. 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 #. Tuff Country has designed after market
upper and lower shock bracket for this vehicle. 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 rec-
ommends installing a 23” fully extended nitrogen gas
loop to loop style shock in the front.
3. Remove the upper skid plate and set aside along with
the hardware.
4. Remove the lower skid plate and discard the skid plate
and hardware.
5. Working on the driver side, attach the torsion bar
removing tool to the torsion bar cross member, making sure
that the unloading bolt in the center of the torsion bar
removing tool is in the small divot of the torsion bar key.
