CAUTION!
Read pages 2-3 of these instructions before starting installation. Failure to do so could result in significant vehicle damage!
IMPORTANT NOTES FOR THIS INSTALLATION:
1. On short bed vehicles, attach Driver’s Side forward bracket on Row 2 to avoid interference with fuel lines.
2. On vehicles with overload springs, switch position of long and short brackets.
3. You may need to move the mounting rail location +/- ½” to ensure frame brackets do not interfere with bed sills.
CAUTION!
Check for obstructions before drilling. Failure to do so could result in damaged fuel or brake lines, structural members, etc.
CURT MANUFACTURING does its best to communicate tow vehicle manufacturer changes; however, it is ultimately the
responsibility of the installer to prevent damage due to installation.

Each mounting rail
must have a bolt in
either of the marked
center holes. Check
for obstructions
before drilling.
NOTE: Some later models will
require exchanging forward long
brackets from front to rear and
or repositioning forward brackets
to ROW 2. This is to avoid
overload springs and brake cable
hangers. Exchanging brackets is
shown here by dashed lines.
