Installation Steps Continued
4. Repeat the cross arm installation procedure for the rear cross arm making sure to position the holes in the angle iron
towards the front of the truck. After spanning the frame, slide the cross arm towards the rear of the truck.
5. Raise the center section in position between the cross arms with the ball cylinder towards the rear of the truck.
The round hitch receiver that protrudes from the top of the center section must fit through the hole in the truck bed.
Using (8) 1/2" carriage bolts and flange nuts, attach the center section to the square holes in both cross arms.
(Finger tight only.)
6. Square the center section and cross arms across the frame. Hang the side plates from the 1/2" studs extending from the
rear cross arm. Fasten them with 1/2" flange nuts finger tight only. Next, bolt the front flange of the sideplate to the front
cross arm using a 1/2" x 1 1/2" hex bolt, 1/2" washer, and 1/2" flange nut as shown in Figure 2. The two holes at the front
of the sideplates should now be aligned with two holes in the frame behind the shock and shock mount. Use the 2" U-bolt
with one flange nut placed loosely to one end of the U-bolt and place the opposite end into the smaller hole at the front of
the sideplate and twist through the frame until the threaded end is protruding out the other hole of the sideplate as shown in
Figure 1. Place the U-bolt bushing over the U-bolt and into the hole of the sideplate and frame. Make sure to penetrate the
frame with the bushing in order for the sideplate to rest flat against the frame. Now attach a 1/2" flange nut and finger tight
only.
7. With the sideplates installed on both sides, torque the U-bolt flange nuts to 110 ft-lbs. and all other 1/2" fasteners to 110
ft.-lbs
in the following order:
First: Torque the U-bolts to the sideplates and frame.
Second: Torque the (8) carriage bolts from the cross arms to the center section.
Third: Torque the side plates to the front and rear cross arms.
