HD-X is accurate naming
These running boards are not flashy, They are strong and somewhat, low profile. Stout and rugged, Made in USA and superior in quality and craftsmanship. No drill application for my 2015 GMC HD2500 gas. My truck is white and the powder coat paint on the running boards is flawless diamond plate. 30-45 minute install. Front mud guards not are not an issue for this model truck. Excellent product. Recommend to all who want quality with this application description.
