Product Details

Frame Notching Plates - C-Notch - 3/16 in Thick - Bolt-On - Steel - Black Powder Coat - GM Fullsize Truck 1973-87 - Kit

UMI's bolt-in frame notch kit enhances axle clearance for lowered trucks, essential for drops over 6 inches. The kit features robust 3/16' laser-cut steel, top-quality hardware, and poly bump stops. While factory frame notching is necessary, UMI's design eliminates the need to cut the valuable bed reinforcement rails. The exclusive inner support plate serves as a convenient template, and a gloss black powder coat finish protects your investment.

UMI’s bolt-in frame notch kit increases axle clearance for lowered trucks over 6. Made from 3/16 laser-cut steel with poly bump stops and top hardware, it preserves bed reinforcement rails. Gloss black powder coat finish included.
