This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

About Product Overview

This CURT ball mount kit is built for the heavy end of towing, rated for a gross towing weight up to 20,000 lbs with a forged steel shank and 2.31" ball. The 2" drop puts your hitch at the right height for lower trailers or when your receiver sits higher than your coupler, keeping the tow bar level for safer, more stable towing.

The shank fits a 2.5" receiver, and forged steel construction with a carbide black powder coat finish means this mount is made to handle serious loads without flexing or corroding over time. It comes as a complete kit, ready to install, so there's no hunting down a separate ball or hardware. Good fit for anyone hauling heavy trailers, equipment, or livestock loads that push past what a standard 1/4-ton hitch setup can handle.

  • Drop: 2 inches, Rise: 0 inches
  • Ball size: 2.31 inches
  • Shank diameter: 2.5 inches, fits 2.5" receiver

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
