Do these mount at the factory headlight locations without drilling or modification?

Yes. These are designed to bolt into existing factory mounting points on your 579 or 587. No drilling, cutting, or panel work needed.

Will these headlights work with my current wiring harness?

Wiring compatibility depends on your specific truck's electrical configuration. Verify bulb type and connector style against your current setup before installation.

What's the return process if these don't fit my truck?

Review our return policy at checkout. Headlights are final sale items once installed, so test-fit and verify compatibility before committing them to the truck.
