This RH 1-1/4"-12 Hex Tube Insert is a heavy-duty, weld-in steel bung built to fit 2.00" inner diameter DOM tubing and machined with 1.25"-12 right-hand threads. The hex head design provides a flat surface for wrenching, making installation and removal easier—ideal for custom suspension, steering, and chassis systems that require strength and adjustability.
Crafted for extreme loads and off-road abuse, this bung is perfect for 1-1/4" Heim joints in demanding builds like rock crawlers, Ultra4 rigs, mud trucks, and custom tube chassis vehicles. Commonly used in oversized 4-link bars, radius arms, and drag links, it offers the strength needed for high-horsepower and heavy-weight vehicles.
