Extreme Max 5001.6521 Weld-On Receiver Tube – 2" I.D. x 18" – Heavy-Duty Raw Steel Hitch Tube with Pre-Drilled Pin Hole & 1/2" Reinforced Collar – for Custom Trailer, Truck & Equipment Fabrication

The Extreme Max 5001.6521 Weld-On Receiver Tube is built for fabricators, trailer builders and equipment upfitters who demand strength, precision and simplicity in every weld. Featuring a true 2" x 2" receiver opening, this tube is compatible with virtually any standard hitch accessory—ball mounts, winch carriers, cargo carriers, bike racks and more—making it an extremely versatile base component for custom towing and utility applications. Constructed from heavy-duty raw steel, the tube arrives with a clean, weld-ready surface so you can go straight to fitting and welding without spending extra time grinding or sanding. This saves both labor and consumables in busy fabrication environments or DIY projects. To speed installation even further, the tube includes a pre-drilled hitch pin hole, allowing you to secure accessories immediately after welding without additional drilling or layout. At the business end, a 1/2" reinforced collar surrounds the receiver opening. This added material helps prevent the mouth of the tube from spreading, mushrooming, or deforming over time, even under repeated loading, dynamic forces, or off-road use. With an overall length of 18", the receiver tube provides generous weld area and layout flexibility. It can be integrated into trailer tongues, truck bumpers, flatbed frames, agricultural implements, shop tools, or custom racks and carriers—anywhere you need a robust, 2" receiver point. Whether you’re building a new trailer from scratch, upgrading a work truck, or fabricating specialized equipment, the Extreme Max 5001.6521 Weld-On Receiver Tube delivers the durability, compatibility and clean design you need for professional, long-lasting results.
