10) VACUUM HOSE AND ELECTRICAL PLUG RELOCATION…
[DIAGRAM 3] Locate the metal vacuum line that runs along the passenger side frame rail.
This line is attached to a rubber hose that connects to the vacuum actuator valve on the
differential. Remove the metal line’s retaining screws and attach one end of the furnished
vacuum line drop bracket (#55-09-4530) to the frame rail using one of the original screws.
Carefully reform the metal line as necessary and attach it to the lower end of the “09” bracket
using the supplied 1/4” x 1” bolt, washer, and nyloc nut (8).
Unplug the electrical line at the vacuum
actuator valve and release the line’s
plastic retaining clip on the valve
bracket. Reconnect the electrical line to
the valve.
NOTE: If additional slack is needed for
the electrical line when the installation is
complete, remove the line from the top
of the crossmember and relocate it to
the bottom of the crossmember. The
line’s retaining clips can be reused.
11) TRACK BAR BRACKET…
[DIAGRAM 4] Prior to installing the
track bar bracket, remove the bolt clamp
that holds a steel brake line from the
crossmember. Carefully push the line
up and out of the way approximately 2
inches.
[DIAGRAM 5] Position the track
bar drop bracket (#55-22-4530)
against the factory track bar
mount to get an idea where the
drop bracket will make contact
with the original mount. Closely
examine the factory mount to be
sure its surface is smooth where it
makes contact with the Superlift
bracket. Some heavy-duty
models have a reinforcement
plate welded to the mount that
MUST be ground smooth. Also
check the fit of the gusset on the
“22” bracket that contacts the
bottom of the frame for later
welding (see diagram 7 for
reference). In some cases it may
be necessary to trim the gusset
slightly so that the bracket fits flush with the factory track bar mount. Grind as necessary,
then check-fit the “22” bracket once again to ensure it fully contacts the factory mount.
