99-05 Chevy Silverado AirBar ABAR11007 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.
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 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.
3. Using a saw or a cutoff wheel, trim the framerail on the marked lines.
4. Install the c notch onto the framerail. The C notch fits between the tube style crossmembers located in front of and behind the axle, so there is only one way they will fit. [NOTE: on 1999 and 2000 model trucks the framerail is approx. ž” shorter in height than the later models. A spacer plate is provided to adapt our notches to these applications. It is installed between the bottom of the frame and the C notch.] Using the holes in the C notch as a template, drill through the framerail and attach using the included hardware.
