This is the heart of B\u0026amp;W’s Turnoverball system, delivering serious towing strength without sacrificing your truck bed’s everyday functionality. With a 30,000 lb capacity, it's built to handle gooseneck trailers, toy haulers, livestock rigs, and more without breaking a sweat. What makes it even better is how cleanly it fits beneath the bed, giving you a flat surface when the ball is flipped over and stored. No need to remove the bed or weld anything, and the install uses factory frame holes, making the process straightforward. It’s a perfect match for 2011-2018 Silverado and Sierra 2500HD and 3500HD models with the 6.6L Duramax, so you know it’s built for the kind of trucks that actually get work done. Whether you're hauling for business or adventure, this center box makes sure your truck stays ready for both.\u003c\/p\u003e\n\u003ch4\u003eBuilt To Match Your GM Duramax Like A Glove\u003c\/h4\u003e\n\u003cp\u003eThe B\u0026amp;W GNRC912 Turnoverball Center Box is designed to work seamlessly with the GNRM1016 mounting kit, forming a complete gooseneck hitch system for GM Silverado and Sierra 2500HD and 3500HD models from 2011 through 2018 with the 6.6L Duramax engine. It installs directly beneath the bed and requires just a 4-inch hole for the ball and four small holes for the included safety chain hookups. Because it uses pre-existing holes in the truck’s frame, there’s no need for welding or additional fabrication. This not only preserves your truck’s structural integrity but also makes the install cleaner and quicker. The Turnoverball design lets you store the ball upside-down in the socket when not in use, keeping the bed level and fully usable. Made from high-strength steel and backed by B\u0026amp;W’s reputation for durability, this center box delivers dependable performance mile after mile. Whether you're building a new towing setup or upgrading an existing one, this part is built to handle real-world demands with ease.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCenter box only, mounting kit sold separately\u003c\/li\u003e\n\u003cli\u003eDesigned to work with B\u0026amp;W GNRM1016 mounting kit\u003c\/li\u003e\n\u003cli\u003eCompatible with 2011-2018 GM Silverado and Sierra 2500HD\/3500HD\u003c\/li\u003e\n\u003cli\u003eFits trucks equipped with the 6.6L Duramax diesel engine\u003c\/li\u003e\n\u003cli\u003eRequires a 4-inch hole in the truck bed for ball access\u003c\/li\u003e\n\u003cli\u003eAlso requires four small holes for safety chain hookups\u003c\/li\u003e\n\u003cli\u003eInstalls under the bed without any welding or bed removal\u003c\/li\u003e\n\u003cli\u003eUses existing frame holes, no drilling into the frame needed\u003c\/li\u003e\n\u003cli\u003eIntended for use with factory-installed truck beds only\u003c\/li\u003e\n\u003cli\u003eGooseneck ball stores inside receiver when not in use\u003c\/li\u003e\n\u003cli\u003eMade in the USA and built from heavy-duty steel\u003c\/li\u003e\n\u003cli\u003eInstallation should be done with proper tools and safety measures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"B\u0026W Hitches","offers":[{"title":"Default Title","offer_id":68060768239889,"sku":"BNW-GNRC912","price":384.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/s-l1600_f4334a09-057b-4571-bf59-4a26cb78ed28.jpg?v=1794724503","url":"https:\/\/gautoparts.com\/products\/b-w-gnrc912-turnoverball-center-box-11-18-gm-6-6l-duramax","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
