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.
WARNING:
DO NOT lubricate threads. It may cause bolt failure.
11. Torque all nuts to 85 lb-ft
12. Pull wire provided to pull rib neck bolts through frame as needed per application
Fig. 2
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. Cequent 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.
