Prothane 4-1016 Leaf Spring Eye Shackle Bushing Kit

The Prothane 4-1016 Leaf Spring Eye and Shackle Bushing Kit replaces worn or degraded OEM rubber bushings in leaf spring suspension systems with premium-grade polyurethane components. Leaf spring suspensions place significant stress on pivot points and shackle connection points — making bushing condition critical to ride quality, handling, and alignment stability.

Prothane's polyurethane formulation resists compression, oil, and road chemicals far better than factory rubber, restoring proper suspension geometry and reducing unwanted flex. All included sleeves and hardware are precision-machined for a direct, exact fit with no modification required.

Key Features:

• Premium-grade polyurethane construction for long-lasting durability
• Resists oil, grease, road salt, and environmental degradation
• Firmer than OEM rubber for improved handling and reduced body roll
• Precision-fabricated sleeves and hardware included for a perfect fit
• Direct replacement for soft or blown-out factory rubber bushings
• Restores proper suspension pivot geometry and reduces spring wander
• Complete kit includes all necessary bushings and sleeves

Prothane polyurethane suspension components are a trusted upgrade for enthusiasts and daily drivers alike, offering a noticeable improvement in suspension response and component longevity over standard OEM rubber parts.
