Do I need fasteners to mount these, and what hardware is required?

These panels mount to your existing fender mounting points and bolt holes. Hardware is not included — verify your vehicle's fastener size and quantity by checking your OEM service manual or inspecting factory fender attachment points before ordering fasteners separately.

What prep and finishing work should I do before installation?

Sand the primer surface lightly to promote paint adhesion, then apply your chosen primer and topcoat. Installation happens after your finish is complete, so plan for painting before bolting the panels on.

Will these panels fit with aftermarket wheel fitments or extended suspension?

These are designed as direct bolt-on over-fenders using factory mounting locations. If your vehicle has significant suspension changes or wider wheel offsets, test-fit before final installation to ensure tire clearance and panel alignment with your modified geometry.
