The bottom line: these zinc coated square U-bolts are best for routine rear lift block or leaf spring reassembly where correct fitment for 2.5in wide springs and a measured 8.75in length matter. The reviewer found them straightforward to install, solidly threaded, and purpose-built for stock-style suspension work without extras that complicate selection.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Designed specifically for 1988-1998 Chevrolet and GMC C1500 models and 1999-2019 Silverado and Sierra 1500 trucks, ensuring a correct match when vehicle selection is verified.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Zinc coated square U-bolts resist corrosion better than bare steel, helping maintain clamp strength in typical road conditions.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e The 8.75in length and 9\/16in diameter are measured from the bottom of the bend to the thread end, giving consistent sizing for rear lift block and leaf spring reinstallation.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e The set includes four square U-bolts with mounting hardware as shown, so buyers receive a full replacement kit for one axle installation.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Suitable for 2.5in wide leaf springs and usable on left, right, front or rear placements when the vehicle requires square U-bolt geometry.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is for DIY truck owners, mechanics and hobbyists working on Chevrolet C1500 or GMC C1500 models from 1988-1998, and Silverado\/Sierra 1500 trucks from 1999-2019 who need a direct-fit set of square U-bolts for leaf spring clamping or rear lift block reassembly.
