Installing the Bar
The new KC bar will attach to the outside of each frame rail using the two bumper bolts and
one of the tow hook bolts.
1. Remove the nuts from the passenger side bumper bolts and the tow hook bolt on the outside of
the frame. Push the bolts in until the ends are
flush with the outside of the frame.
2. Remove the nuts and bolts from the drivers
side bumper bracket and tow hook. Insert the
bumper mounting bolts from the inside of the
frame so they are a mirror image of the
passenger side bumper mounting bolts.
3. Position the light bar bracket marked DRIVERS
SIDE so that the two upper mounting holes of
the bracket align with the bumper mounting
bolts and the lower mounting hole with the tow
hook bolt.
4. Insert the bumper mounting bolts through the
light bar and start the nuts.
5. Insert the supplied spacer between the frame
and light bar and insert the tow hook bolt.
Loosely tighten hardware allowing for
adjustment.

bracket.
7. Mount the light bar between the two brackets
using the supplied hardware. Loosely tighten
nuts and bolts allowing for adjustment.
