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 passenger side. Next, remove the tires and 
wheels from both sides. 
 
2. Remove the stock lower skid plate and discard the 
stock lower skid plate and hardware. 
 
3. Remove the stock front upper plate. If you are going to 
re-install the stock upper skid plate back into the stock 
location, save the (3) stock upper bolts, (2) stock lower 
bolts and the stock front upper skid plate for later re-
installation. If you are not going to re-install the stock 
front upper skid plate, save (2) stock bolts and discard all 
the other stock hardware and the stock front upper skid 
plate. 
 
4. Remove the stock front driveline from the stock 
location, and save the stock driveline and hardware for 
later re-installation. 
 
5. Working on the driver side, remove the stock shock 
from the stock location. The stock shock and hardware 
may be discarded. Special note: New longer front 
shocks are needed, if you have not already ordered 
shocks, please contact Tuff Country or your local 
Tuff Country dealer and order the proper shocks. Tuff 
Country recommends using a 23” fully extended 
nitrogen gas shock. Repeat procedure on the 
passenger side.

7. Working on the driver side, attach the torsion bar 
removing tool to the stock 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 stock 
torsion bar key. Adjust the torsion bar key up high 
enough so that the stock small metal adjusting block and 
bolt can be removed. Set the stock torsion bar block and 
hardware aside for later re-installation. Repeat procedure 
on passenger side. 
 
8. 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. Tap the stock 
torsion bars forward until the stock torsion bar cross 
member can be removed. Once you tap the stock torsion 
bar out of the stock torsion bar cross member, the stock 
torsion bar key will fall out. Set the stock torsion bar key a 
side for later re-installation. Repeat procedure on the 
passenger side. 
 
9. Working on the driver side, remove the stock hardware 
that connects the stock torsion bar cross member to the 
stock mounting point. Set the stock hardware aside for 
later re-installation. Special note: The stock mounting 
point is on the inside of the stock frame rail. Repeat 
procedure on the passenger side. Remove the stock 
torsion bar cross member from the stock location and set 
aside for later re-installation. 
 
10. Working on the driver side, slide the stock torsion bar 
out of the stock rear lower control arm and set aside for 
later re-installation. Repeat procedure on passenger side. 
 
11. Working on the driver side, remove the stock sway 
bar end link from the stock location and discard the stock 
end link and stock hardware. Special note: New end 
links and bushings are included with this suspension 
system. Repeat procedure on the passenger side. 
 
12. Working on the driver side, remove the stock nut that 
connects the stock outer tie rod ball joint to the stock 
steering knuckle. Set the stock nut aside for later re-
installation. Carefully break the stock taper on the stock 
outer tie rod ball joint and remove the stock outer tie rod 
from the stock knuckle. Special note: Take special care 
not to rip or tear the stock outer tie rod ball joint dust 
boot.
