Do I need to remove the factory fenders to install these?

No. Over fenders bolt directly over your existing fenders. Verify mounting hole locations on your vehicle match standard over fender patterns before drilling.

What prep work is required before painting?

Sand the surface with fine grit to promote paint adhesion, then wipe clean of dust. Apply your choice of base coat, primer, or color coat directly. Follow your paint manufacturer's cure and hardening times.

Will these fit without modifying the body or suspension?

Yes. Over fenders are designed to install on top of factory fender lines without cutting, welding, or suspension changes. They will increase your vehicle's overall width slightly at the fender area.
