Do I need any special fasteners to install this?

It mounts directly at your factory attachment points. Bring a basic socket set and your vehicle's service manual to confirm the correct hardware and torque specs for your specific model year.

Will this bracket work if my bumper has been replaced?

As long as your replacement bumper has the same factory mounting points as the original CC bumper, you're good. If the mounting location has shifted, test-fit the bracket before committing to fasteners.

Does the black finish need any prep or sealing?

The finish is ready to install as-is. No painting or prep needed. If you want extra durability against UV or road salt, a clear coat is optional.
