and sleeves into the upper eyelet of the new shocks.
Special Note: Shocks are not included with this
suspension system, shocks need to be ordered as a
separate part number, Tuff Country EZ — Ride
Suspension recommends using a 23” fully extended
nitrogen gas shock. Make sure to use a lithium or
moly base grease prior to inserting the new bushings
into the new shock. This will increase the life of the
bushing as well as prevent squeaking. Install the lower
shock bushing and the proper sleeve into the lower
eyelet of the new shock. Special Note: Make sure to
use a lithium or moly base grease prior to inserting
the new bushings into the new shock. This will
increase the life of the bushing as well as prevent
