Belltech rear C-notch kit for 2015-2026 Ford F-150 2WD and 4WD short-bed trucks, all cab styles. The kit uses outer C-notch shells and inner support plates at both frame rails.
 
The notch gives the rear axle more upward travel on a lowered truck. Outer shells and inner plates clamp around the cut frame area to reinforce it, while the supplied template locates the cuts. A relocation bracket moves the driver-side brake-line bracket clear of the notch.
 
Includes left and right outer C-notches, left and right inner support plates, brake-line relocation bracket, cutting template, two bump stops, mounting hardware, and instructions. Part 6647.
