8. Mark 4 holes on the truck bed, using whichever one of the three 5/8” slots at each end if the rail that line up best with the frame
mounting brackets below. (Hole location will vary for individual vehicle applications.) Drill all holes with 3/16" drill and enlarge them with
a 21/32" drill. Always use sharp drill bits. A 3/16" pilot hole will greatly speed drilling larger holes. Install tube spacer between rail and
bed, install 5/8” carriage bolts into holes. Install filler spacer above or below bed to fill corrugations in bed floor. Install serrated washers
and nuts.
9. Install mounting brackets onto carriage bolts. Use the left and right angled frame brackets at locations where frame obstruction will not
allow the frame brackets to be positioned. Secure bolts through mounting brackets with serrated washers, hex nuts. (SEE FIG. 4)
10. Drill two 17/32” holes in truck frame for each frame bracket. Select the holes which will give the greatest spread between bolts.
Install eight 1/2”-13x1-3/8” ribbed neck bolts, (threads pointing out), serrated washers, and hex nuts. Tighten nuts until bolt heads seat.
Lubrication of knurls of all rib neck bolts is recommended.
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.
Note: On vehicles with heavy duty suspensions, check for interference with bolts where brackets are mounted to
frame. If interference with suspension spring results, cut bolt flush to nut outboard of frame or use weld option.
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.
11. Torque all 1/2” nuts to 85 lb-ft and all 5/8” nuts to 120 lb-ft.
12. Pull wire provided to pull rib neck bolts through frame as needed per application.
WARNING:
DO NOT lubricate threads. It may cause bolt failure.
