Will this fit my bumper beam and sensor holes?

This is a direct replacement bumper cover. Before install, verify that your existing bumper beam, mounting points, and any OEM sensor cutouts align with the K-2 design. You may need to drill or enlarge sensor holes depending on your vehicle's existing wiring and hardware setup.

Do I need to remove the lower valance or air dam?

That depends on your vehicle's configuration. The K-2 profile sits at the front end, so inspect how your factory air dam and lower trim pieces interact with the new bumper cover's shape. You may need to modify or refit those panels for clean lines. Measure twice before cutting or drilling anything.

What should I do to prep this before paint?

Sand and prep the surface before applying your chosen primer and color. FRP accepts polyester and urethane finishes well. Ensure all mounting points are clean and dry, and seal any gaps between the bumper cover and adjacent body panels with appropriate trim or sealant once painted and installed.
