How much tire clearance do these add?

These are cap-style flares that follow the factory fender line—they do not add significant wheel well depth. Verify your current tire and wheel fitment before installation to ensure existing clearance is adequate for your setup.

Do these require drilling or modification to the factory fender?

These caps are designed to work with existing factory mounting points. No cutting or drilling of the fender structure is required—installation relies on the OEM attachment system.

What prep work is needed before painting?

Sand the surface with appropriate grit and apply a base coat of your chosen color, followed by clear coat. Standard automotive paint prep procedures will ensure even coverage and adhesion.
