Do these require any prep work or painting before installation?

The silver finish is ready to bolt on as-is. If you prefer a different color or want a custom match, light sanding and your choice of automotive spray paint will work fine.

What fasteners do I need to mount these?

Hardware is not included with the bars themselves. You'll need to source bolts and fasteners that match your vehicle's factory rocker attachment points—check your service manual or test-fit first to confirm size and quantity.

Can I install these myself, or do I need a lift?

Most DIYers can handle this with basic hand tools and jack stands. Access under the rocker panels is tight but doable. A lift makes the job faster and safer if you have one available.
