iiLentes rear leaf spring hanger bracket and shackle kit replaces worn mounts and shackles on 1999–2013 Chevy Silverado 1500 and GMC Sierra 1500 trucks for restored suspension alignment and improved load support.

If your truck rides unevenly, makes creaks over bumps, or shows visible wear around the leaf spring mounting points, this complete iiLentes hanger and shackle kit is designed as a direct-fit replacement for factory parts. The kit contains the two hanger brackets, two shackles, and all necessary hardware so you can swap out tired components and return your rear suspension to proper geometry without fabricating or modifying parts.

How will this kit affect ride quality and spring longevity?

Replacing fatigued hangers and shackles restores the correct alignment and support for the leaf springs, which reduces unwanted movement and metal-on-metal contact. That stability lowers stress on the springs and mounting bolts, helping the suspension perform more consistently under load.

• Reduces lateral and fore-aft play in the spring mounts
• Minimizes noise from worn pivot points
• Helps distribute load evenly across spring leaves
