99-01GM Sierra / Silverado rear AirBar installation
1. Raise truck to a comfortable working height and support safely with jackstands under the frame.
Place these stands ahead of the leafspring mount and at the rear of the frame to support it when the
C notch is installed.
This is the layout for cutting the frame
for the C notch. Using a 1/2” drill to
make the corners produces a rounded
corner which is much less susceptible
to a stress crack.
2. The C notch frame section
will be installed first. Note that
the front edge of the C notch
is butted up to the round tube
crossmember. Place the C
notch against the framerail to
scribe the outline for cutting
the framerail. Be sure to
“round” the corners of the cut
to avoid any stress points.
