INSERT CROSS ARMS BETWEEN
TRUCK BED & FRAME RAIL
FRAME RAIL
1) Install cross arms by sliding them into gap between the truck bed and frame from inside the wheel well. As shown in Figure 1.
2) For all applications, the notched side plate indicates that it is for the driver side. Hang the side plates from 5/8" studs, which
extend from the cross arms. Fasten each plate with two 5/8" flange nuts provided. Finger tight only.
3) Using the U-Bolt and U-Bolt bushing as shown in Figure 3 (Page 2), secure each side plate to existing holes in the frame rail.
Use 1/2" flange nuts to secure in place. Finger tight only.
4) Rotate the cross arms until they contact the truck bed. Center the rear cross arm studs in the side plate slots as shown in Figure 2.
Use a 15/16" wrench to tighten the 5/8" flange nuts on the rear cross arm to the side plates. Repeat for front cross arm.
(Use the tube spacer for correct spacing between the cross arms.)
(Note: Do not tighten cross arms until center section installation is complete.)
5) Be sure the cross arms are vertical to the truck bed before drilling! With cross arms secure and evenly spaced, drill a hole through
the truck bed at the center of each cross arm mounting hole.
6) From inside the truck bed, center the six pilot holes with the letter "A" on the C-52 cutting template. Fasten the template to the truck bed
with tape. Once fastened, drill four 1/8" pilot holes through section lettered "B".
(Be sure to check for brake lines and/or fuel lines before drilling.)
7) With the pilot holes drilled, use a sabre saw to cut out section "C".
8) Remove template and drill out the six pilot holes with a 21/32" drill bit. Set your C-52 folding hitch ball into place.
9) Attach the C-52 to the cross arms using six 5/8" carriage bolts and flange nuts. Torque bolts to 210 lb-ft.
(Note: Spacers must be installed at all bolt locations to prevent truck corrugations from collapsing.)
10) After the C-52 has been fastened to the cross arms. Torque all 5/8" hardware to 210 lb-ft.
11) Torque all 1/2" hardware to 110 lb-ft.
