8. With the 5 th wheel assembly in the bed of the truck, position the rear rail as directed in figure 2 on the previous page.
9. Drill an 1/8” hole through the bed in the inside hole locations of the front rail as shown in figure 1. This should be
approximately in the middle of the bed hat channel. Drill down through the bottom of the bed hat channel with the 1/8”
drill.
10. Place the front frame brackets under the bed to verify that the 1/8” holes align with the slots in the frame brackets. The
frame brackets should be against the rear side of the hat channel. Drill the holes in the bed to 1-
1/4” with the hole saw.
Drill the hole in the bottom of the hat channel to 5/8”. See figure 1.
11. Insert 5/8” x 6” carriage bolts down through the rail. Insert the 1-1/4” tube spacer under the rail with the 5/16” thick
spacer plate. Put the 2-
7/16” long spacer down into the hat channel with the 5/16” thick plate on top of it. The 5/16”
thick plate needs to be between the bed corrugations and the rails so that there is no gap under the rails. Install
serrated washers and nuts on the bolts. Hand tighten.
12. Using the holes in the frame brackets as a guide, drill 17/32” holes into the frame. Use the pull wire and an access hole
in the frame to pull rib neck bolts into the frame. Install serrated washers and nuts on the bolts. Snug up the nuts.
13. With the 5 th wheel hitch in the rails, mark the hole location of the rear rail bolt locations using the inside bolt locations.
See figure 1.
14.
Drill a 5/8” hole through the bed. Place a 5/16” thick spacer over the hole and the 1-1/4” tube spacer above the 5/16”
spacer. Place the rail over the spacers and insert the 5/8” x 3-1/2” carriage bolts. See figure 1.
15. Place the rear frame brackets over the 5/8” bolts. Left rear and right rear brackets can be interchanged if it makes
installation easier. Install 5/8” serrated washers and nuts on the bolts.
16. Follow step 12 to install 4 rib neck bolts into the rear frame brackets.
17. Torque all ½” nuts to 85 ft.\ lb. and all 5/8” nuts to 150 ft / lb.
CAUTION:
It is important that 17/32" drill be used for holes in chassis frame as rib neck bolts
may break if too small a hole is used and neck may not grip if too large a hole is used.
CAUTION:
Check for obstructions before drilling. Failure to do so could result in damaged fuel or brake lines,
structural members, etc. TOWING PRODUCTS does its best to communicate tow vehicle
manufacturer changes; however, it is ultimately the responsibility of the installer to prevent damage
due to installation.
WARNING:
DO NOT lubricate threads. It may cause bolt failure.
