Tuff Country 10795 - GM 73-87 Traction Bars - Manual (Page 3)

Traction bar installation:
1. To begin installation, block the front tires of the vehicle so
that the vehicle is stable and can’t roll forward. Safely lift the
rear 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 wheels and tires from both sides and
set aside for later re-installation.
2. Working on the rear axle, place a pair of hydraulic floor
jacks under the rear differential. Place one on the driver side
and one on the passenger side.
3. Locate the new rear traction bar brackets. Working on the
driver side, remove the u-bolt nuts and washers and save for
later re-installation. Install the new rear traction bar bracket
to the inner legs of the u-bolts. Secure using the u-bolt nuts
and washers that where removed earlier in this step. Torque
to 120 ft lbs. Repeat procedure on the passenger side.

4. Locate the new rear traction bars. Also, locate (4) PB2408
poly bushings and (2) S10082 sleeves from hardware bag
10795NB1. Install the new poly bushings and sleeves into
each end of the new rear traction bars. Special note: Make
sure to use a lithium or moly base grease prior to insert-
ing the new bushings and sleeves into the new rear trac-
tion bars. This will increase the life of the bushing as
well as prevent squeaking.
5. Working on the driver side, hold the all thread part of the
new rear traction bar up to the stock spring hanger and
scribe a mark. Special note: When doing this we want to
make sure that once the hole is drilled we have enough
material that we will not damaged the stock spring hang-
er. Carefully drill a 7/8” hole into the stock spring hang-
er. Repeat procedure on the passenger side.

6. Locate (4) new MO3808 poly bushings, (4) S10113 over
size washers and (4) 1/2” fine nuts from hardware bag
10795NB1. On both rear traction bars, install (1) new 1/2”
fine nut all the way up the all thread on the new rear traction
bar. Slide the new over size washer onto the all thread and
then install the MO3808 poly bushing. Working on the driver
side, install the new rear traction bar to the previously drilled
hole in the stock spring hanger. Secure using the new
MO3808 poly bushing, over size washer and the new 1/2”
fine nut. Do not tighten at this point. Repeat procedure on
the passenger side.

7. Locate (2) new 9/16” x 3 1/2” bolts, (4) 1/2” USS flat wash-
ers and (2) 9/16” unitorque nuts from hardware bag
10795NB1. Working on the driver side, install the rear trac-
tion bar to the previously installed rear traction bar bracket
and secure using the new 9/16” x 3 1/2” bolt and hardware.
Make sure to use thread locker or lock tite and torque to 80
ft lbs. Special note: There are (3) holes on the new rear
traction bar bracket, we want to install the traction bar to
the center hole, if this does not work on the vehicle that
you are working on, install the new rear traction bar to
the hole that best fits your vehicle. Repeat procedure on
the passenger side.

8. Carefully remove the hydraulic floor jacks from under the
rear differential.
9. Re-install the tires and wheels and carefully lower the
vehicle to the ground.
10. With the weight of the vehicle on the ground, working on
the driver side, tighten the front and rear 1/2” fine nut that
connects the rear traction bar to the stock spring hanger.

Congratulations, installation complete. If you have any
questions or concerns, please feel free to contact Tuff
Country EZ-Ride Suspension.
Tuff Country EZ-Ride Suspension recommends that a
complete re-torque is done on all bolts associated with
this suspension system. It is the customers responsibil-
ity to make sure that a re-torque is performed on all
hardware associated with this suspension system after
the first 100 miles of installation. It is also the customers
responsibility to do a complete re-torque after every
3000 miles or after every off road use. Neglect of follow-
ing these steps could cause brackets to come loose and
cause serious damage to the suspension system and to
the vehicle.
