129. Locate the new rear shocks. Special Note: New
longer rear shocks are needed once this suspension
system has been instead and the new rear shocks
need to be ordered as a separate part #. If you have not
already ordered your new rear shock, please contact
Tuff Country or your local Tuff Country dealer and
order your new rear shocks. Tuff Country recommends
using a 26” fully extended nitrogen gas shock in the
rear of your vehicle. Locate (4) new S10107 over size
washers from hardware bag 55907NB. Also, locate (4)
PB8297 front upper shock bushings from 55907NB1. Install

of your new shocks. Special note: The new bushings
and sleeves are supplied with your new shocks. Also,
make sure to use a lithium or moly base grease prior to
inserting the new bushings and sleeves into the new
shocks. This will increase the life of the bushings and
will help prevent squeaking. Install the new shock boots
onto the new shocks. Special note: The new shock boots
are not included with this suspension system and the
new shock boots need to be ordered as a separate part
#. If you have not already ordered your new shock
