U-Bolt for 3in Axle Tube

The ALLSTAR PERFORMANCE U-Bolt for 3-inch Axle Tube (ALL 68344) is a heavy-duty fastening component engineered for axle assembly and suspension mounting applications. This 1/2-20 right-hand threaded u-bolt delivers the precision fit and structural integrity required in motorsport fabrication, off-road vehicle builds, and trailer suspension systems where axle control and component alignment are mission-critical.

Built from steel with a cadmium finish, this u-bolt measures 10 inches in length with a 3-inch inner diameter, providing the exact span needed for standard axle tube mounting. The cadmium plating delivers corrosion resistance suitable for harsh environments—critical for vehicles exposed to moisture, salt air, or off-road conditions. The 1/2-20 thread specification ensures compatibility with standard fastening hardware and provides reliable load distribution across the mounting surface. Universal fitment means this component integrates into a wide range of fabrication projects without application-specific limitations.

This fastener is essential for builders and technicians working on axle assembly, suspension upgrade, or frame-mounted component installation. Whether securing an axle tube to a frame rail, mounting a differential housing, or fastening suspension components during vehicle fabrication, the u-bolt's geometric design distributes clamping force evenly to prevent binding, slippage, or stress concentration. The right-hand thread designation ensures predictable tightening behavior and compatibility with standard wrenches and torque specifications used across motorsport and fabrication shops.

ALLSTAR PERFORMANCE u-bolts are industry-standard fastening solutions in drag racing, circle track, street rod, and off-road fabrication communities. The cadmium finish and precision thread specification make this component suitable for performance applications where vibration resistance and long-term corrosion protection are non-negotiable. Individual units allow builders to purchase exactly what they need for their specific project requirements.
