Do I need to source mounting hardware separately?

Yes. The bar itself comes assembly-ready, but you'll need to source bolts and fasteners for your vehicle's factory rocker points. Check your truck's service manual for the correct grade and torque spec.

Can I paint this before installation?

You can, but most installers bolt it up first, then mask and paint on the truck. That way seams around mounting points stay clean and factory-looking. If you paint before install, be ready to touch up around fastener holes.

Will this fit if I've added a suspension lift or lowering kit?

Mounting method is designed around factory rocker geometry. If your truck's ride height has changed significantly, test-fit before committing fasteners. Major suspension changes can shift the angle and contact points.
