Prothane 7-1004-BL Leaf Spring Eye & Shackle Bushing Kit - Black Polyurethane

Prothane's 7-1004-BL Leaf Spring Eye and Shackle Bushing Kit is engineered to restore and improve suspension performance in leaf spring-equipped vehicles. In leaf spring suspensions, extreme forces are concentrated at the pivot points and shackle mounting locations — making worn or soft OEM rubber bushings a primary cause of handling vagueness, axle wrap, and premature suspension wear.

This kit replaces the factory rubber bushings with premium-grade black polyurethane, a material that offers significantly greater durability, resistance to oil and chemicals, and superior load-bearing capability compared to stock rubber components. Polyurethane maintains its shape and firmness over time, helping to preserve proper axle alignment and improve throttle response under acceleration.

Key Features:

• Manufactured from high-quality black polyurethane for extended service life
• Resists compression, oil, ozone, and chemical degradation
• Precision-fabricated sleeves and hardware included for a perfect OEM-style fit
• Firmer bushing material reduces axle wrap and improves handling response
• Direct replacement for soft or deteriorated factory rubber bushings
• Complete kit includes all necessary bushings and related hardware

The Prothane 7-1004-BL is a straightforward upgrade for enthusiasts and daily drivers alike who demand reliable suspension geometry and long-lasting performance. All components are precision fabricated to ensure correct fitment and hassle-free installation.
