Do these require hardware to install, or do they just clip on?

These mount directly to factory handle points — no fasteners or adhesive needed. They're designed to slip over existing hardware and stay secure during normal door operation.

Will these fit both the inside and outside handles?

Yes, this set covers all four doors, inside and outside. Make sure to test-fit before final installation to confirm alignment with your specific truck's handle geometry.

Can I paint these, or do they come ready to install?

These arrive unfinished ABS. You can leave them raw, paint them to match your truck, or apply protective coating depending on your preference. Sand lightly and use ABS-compatible primer and paint if customizing.
