Spring Shackle Steel 2pk

The Spring Shackle Steel 2pk from ALLSTAR PERFORMANCE is an essential suspension component for builders and enthusiasts upgrading leaf spring systems on classic and custom vehicles. Spring shackles serve as the pivot point that allows leaf springs to articulate and absorb road forces while maintaining frame geometry. Whether you're restoring a vintage truck, building a hot rod, or modifying a classic car chassis, quality shackle plates are critical to proper suspension alignment and longevity.

This two-pack features heavy-duty steel construction with black powder coat finish to resist corrosion and wear. Each shackle plate measures 9 inches in length, 2 inches in width, and 1/4 inch thickness—dimensions optimized for load distribution and durability under dynamic suspension articulation. The 1/2-inch drilled holes provide a secure mounting interface with standard leaf spring fasteners, ensuring a tight, rattle-free connection that maintains alignment through hard driving. The substantial 2.29 lb weight per pair reflects the robust steel stock required for reliable performance in both street and off-road applications.

These shackle plates work with most traditional leaf spring setups common to trucks, muscle cars, and custom chassis builds from the 1960s through modern reproductions. Installation is straightforward—simply bolt the shackles between the frame bracket and leaf spring eye using grade-appropriate hardware. The black finish blends seamlessly into undercarriage components while providing a protective oxide layer. Whether you're fabricating a complete rear suspension or refreshing worn pivot points on a restoration, this two-pack ensures you have a matched pair of critical structural components that will handle the demands of your project.
