WARNING
Read pages 2 - 4 of this installation manual before beginning the
installation. Failure to do so could result in significant vehicle damage.
Check for obstructions prior to drilling. Failure to do so could result in
damaged fuel or brake lines, structural members, etc.
CURT does its best to communicate tow vehicle manufacturer
changes. However, it is ultimately the responsibility of the installer
to prevent damage due to installation.
IMPORTANT NOTES
Use the #16304 add-on kit with the #16100 universal kit.
The mounting holes for row 3 go through the inside of the bed sill.
Make sure it lines up correctly. Drill through the bed and the top of
the frame on both sides. For the row 4 passenger-side attachment,
drill through the bed and top of the frame as well.

Additional Notes
The rear rail on the passenger
side is secured directly to the
frame with 3" carriage bolts
provided in the #16304 kit.
For the row 3 attachment, a tube
spacer should be placed inside the
bed sill on top of the frame and
under the bottom of the bed. Line
up the spacer with the drilled hole
before inserting the carriage bolt.
Repeat for both sides. See figure 1.
For the row 4 passenger-side
attachment, stack two 1/2"
spacers and a beveled washer,
provided in the #16304 kit, to
fill the gap between the bed and
the frame. Use another beveled
washer, conical toothed washer,
and hex nut to fasten the 3"
carriage bolt in place. See figure 1.
Install the long brackets on the
front base rail and the short
bracket on the rear driver-side
base rail using the 1-3/4" carriage
bolts provided in the #16304 kit.
All other attachments to the bed
use 2" carriage bolts from the
#16100 base rail kit.
