Do these mount at the factory rocker points?

Yes. These bolt to the existing rocker panel mounting locations — no drilling into the body. You'll need basic hand tools and hardware appropriate for your vehicle's fastener size; refer to your service manual for torque specs.

Will these fit with a lifted suspension?

The 6-inch clearance works with most common suspension lifts. Test-fit after installation if you've added significant lift height to confirm step entry angle works for your setup.

Do I need to prime or paint these before install?

The nerf bars arrive primed and ready to bolt on. Paint them before or after installation depending on your preference — both work fine. If you install first, tape around the fastener zones to protect them from overspray.
