Description
Part #: 6415
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.
