Spring Shackle Alum 2pk

The Spring Shackle Alum 2pk from ALLSTAR PERFORMANCE is a precision-engineered pair of aluminum leaf spring shackle plates designed for builders and enthusiasts who demand reliable suspension geometry and repeatable ride characteristics. Spring shackles are critical mounting points that allow leaf springs to articulate smoothly while maintaining alignment under load, making them essential for any vehicle running a traditional leaf spring setup—whether you're building a classic muscle car, a street rod, or refreshing a truck's rear end. This pair delivers the lightweight advantage of aluminum construction without sacrificing the structural integrity required for road or track use.

Machined from durable aluminum and finished in black anodized coating for corrosion resistance, each shackle plate measures 9 inches in length, 2 inches in width, and 3/8 inch thick—dimensions that provide excellent strength-to-weight balance for medium-duty applications. The 1/2 inch mounting holes accommodate standard fasteners and align with factory or aftermarket spring perches, enabling straightforward bolt-on installation. Black anodizing protects against oxidation and UV degradation, ensuring the shackles maintain appearance and function through years of exposure to road salt, moisture, and seasonal temperature swings. The two-piece set allows you to replace both sides simultaneously, guaranteeing matched geometry and consistent suspension behavior on both sides of the vehicle.

Builders tackling leaf spring restorations, lowering kits, or custom suspension geometry will find the Spring Shackle Alum 2pk ideal for reducing unsprung weight while improving ride quality and handling response. The aluminum construction is particularly valued in performance applications where minimizing mass at the wheel and suspension points reduces inertia and improves acceleration, braking, and cornering performance. Installation requires basic hand tools and alignment verification to ensure leaf springs sit square to the axle centerline; work with a qualified suspension shop if your build involves geometry changes or requires frame modifications for proper fitment.
