Will these panels block access to my jack points?

No. These side skirts mount at factory rocker locations and maintain clearance for OEM jack point access. Verify your vehicle's jack point geometry before final installation to confirm adequate clearance for your specific lift equipment.

What prep work do I need before painting?

Sand the surface with standard automotive sandpaper and wipe clean to remove all dust. Apply your choice of primer, base coat, and clear coat following your paint supplier's specifications for FRP substrates.

Do these add ground clearance or reduce it?

These panels follow the factory rocker line and do not materially change ground clearance. They add minimal visual extension below the door jamb without altering approach or departure angles.
