This extra-long square U-bolt kit is designed for heavy-duty leaf spring suspension applications requiring increased clearance and secure clamping force. Manufactured from high-strength 40Cr alloy steel, these U-bolts are built for durability, strength, and reliable performance in demanding conditions.The U-bolts feature M14 x 1.5 metric threads, which are approximately equivalent in diameter to 9/16" hardware but are not compatible with standard 9/16"-18 UNC nuts. Matching metric nuts and washers are included to ensure proper installation and secure fastening.With an inside width of approximately 2.68 inches, these U-bolts are designed to fit 2.5-inch wide leaf springs while allowing proper clearance. The approximate 15.5-inch inside length makes them ideal for lifted suspensions, axle conversions, or custom suspension builds requiring extra thread engagement.The square bend design provides a secure fit on square or semi-flat axle housings commonly found in truck, trailer, and off-road suspension systems.
