GOOSENECK CENTER SECTION INSTALLATION
Note - This step may require an extra set of hands, as the gooseneck center section is very heavy and it will
be hard to hold the part in place as you attach the washers and nuts to secure the center section in position.
1.
Step 1, Figure 3. From underneath the vehicle, raise the gooseneck center section (#1) up to the bottom side of the
rails as shown and route the carriage bolts previously installed in the rails (page 3 fig. 2) through the 4 outside holes
in the center section, and secure using (4) 5/8" dia. conical washer (#2) and (4) 5/8-11 Gr. 8 hex nut (#3).
2.
Step 2, Figure 4. Install the (7) 5/8-11 X 2.00 Gr. 8 hex bolts (#1) , (7) 5/8" dia. flat washers (#2), (7) 5/8" dia.
conical washers (#3) & (7) 5/8-11 Gr. 8 hex nuts (#4) as shown through the rails and the center section. It may be
necessary to utilize the tapered alignment pin (not included) in order to properly align the holes and slots to be able
to securely fasten these parts with the fasteners.
