Will this bolt directly to the factory mounting points?

Yes — this step bar is designed to use the factory rocker points on crew cab trucks. No drilling or frame modification needed for installation.

Do I need to prep or paint this before installing?

The assembly ships ready to install as-is. If you prefer a custom finish, you can sand and paint before mounting — just test-fit first to make sure everything aligns correctly.

What's the weight capacity on the step surface?

Weight capacity is not specified in the product data. Contact support with your specific truck details if load limits are critical for your use case.
