Do I need the right-side bracket too, or can I use just the left?

Both sides support the bumper cover evenly. You can install just the left bracket, but pairing it with the right bracket ensures balanced support and prevents sagging or rattle.

What fasteners or hardware do I need to install this?

Hardware not included with this bracket. You'll need to source fasteners that match your vehicle's factory rocker and frame attachment points—refer to your owner's manual or a Ford service guide for the correct bolt size and torque spec.

Does this bracket come primed, or do I need to prep it before bolting on?

This bracket ships ready to install. If you plan to paint it to match your bumper cover, sand lightly and prime before painting to prevent rust at cut edges.
