Do these require any prep or painting before installation?

These ship ready to bolt on. If you want to paint them to match your van, sand lightly and prime before painting — standard body shop procedure.

Will these work with my factory door handles and locks?

Yes — these are covers that mount over your existing handles. Your locks and mechanics stay unchanged.

What tools do I need to install these?

Basic hand tools and a socket set. Installation takes about 30 minutes per side if you're comfortable working around door panels.
