If you prefer to handle the finish yourself, we offer a fully welded raw steel version ready for your custom paint or coating.
Finally, for the custom fabricator, our raw component kit provides a "blank canvas" of individual parts, allowing you to weld the assembly to your trailer’s exact specifications. Precision remains at the heart of this adapter’s design, allowing for custom drilling on the sides and top to ensure a seamless fit for your specific frame dimensions.
Whether you are a trailer manufacturer or an owner seeking more versatility, this mount is built to handle heavy-duty tasks with ease. Keep in mind that your total towing capacity is always limited by the lowest-rated component in your assembly; therefore, professional installation and high-quality hardware are essential for a safe, high-performance setup.
