Will these fit over my factory handles without any modification?

Yes. These are engineered for direct fit on factory handle geometry. They mount using the existing fastening points — no drilling, grinding, or adapter plates needed.

Do these covers come pre-painted, or do I need to finish them?

They come finished in smooth black. If you want a different color or texture, they accept standard automotive paint after light surface prep.

What fasteners do I need to install these?

Fastener specs aren't detailed in the product data — check your vehicle's service manual or test-fit the covers before purchasing adhesive or hardware to confirm your mounting method.
