Replace a fatigued or rusted shackle before it becomes a safety concern with the Dorman leaf spring shackle, part number 722-122, a steel replacement for the rear, rearward position. It fits many vehicles, among them the 2011-2018 Chevrolet Silverado 2500, 2015-2018 Chevrolet Silverado 3500 and 2011-2019 Chevrolet Silverado 2500 HD. See the Buyer's Guide tab for the full list.
A leaf spring shackle connects the end of the spring to the frame and swings as the spring flexes and changes length under load. Road salt, moisture and years of flexing can weaken it, so a sound shackle matters for a solid rear suspension.
Signs a shackle may need replacing: visible rust or cracking, clunking or squeaking from the rear suspension over bumps, or a rear ride height that sits unevenly. Diagnose the cause before replacing, since other suspension parts can produce similar symptoms.
