9. Install mounting brackets onto carriage bolts with the long brackets on forward bolts and short
brackets on rearward (long and short brackets can be interchanged as needed). Secure bolts through
mounting brackets with serrated washers, lock washers, and hex nuts. Secure the other four bolts
through the bed with flat washers, lock washers, and nuts.
For Installation Assistance or Technical Help, Call 1-888-521-0510
10. Drill two holes in frame for each 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), lock washers, and
hex nuts. Tighten nuts until bolt heads seat. Lubrication of knurls of all rib neck bolts is recommended.
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.
Check for obstructions before drilling. Failure to do so could result in damaged fuel or
brake lines, structural members, etc. Horizon Global America Inc. 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 nuts to 85 lb-ft
12. Pull wire provided to pull rib neck bolts through frame as needed per application
Drill locations will vary. See individual installation for location
Note: See page 18 for a list of required adapter brackets to be used along with the universal brackets.
