Prothane 4-1012-BL Leaf Spring Eye & Shackle Bushing Kit - Black Polyurethane

Prothane's 4-1012-BL Leaf Spring Eye and Shackle Bushing Kit upgrades your leaf spring suspension with premium black polyurethane bushings designed to outlast and outperform the factory rubber components. In leaf spring-type suspensions, the pivot points and shackle attachment locations endure constant and significant forces — making worn or soft OEM rubber bushings a direct contributor to sloppy handling, excessive body roll, and poor suspension response.

Prothane polyurethane bushings resist compression, deterioration, and deformation far better than stock rubber, restoring tight suspension geometry and improving overall ride control. All hardware, sleeves, and related components included in this kit are precision fabricated for a direct-fit, no-modification installation.

Key Features:

• Premium black polyurethane construction for superior durability over OEM rubber
• Replaces worn, soft, or blown-out factory leaf spring eye and shackle bushings
• Precision-fabricated sleeves and hardware included for a perfect fit
• Resists oils, road chemicals, and extreme temperature fluctuations
• Restores suspension tightness and improves handling response
• Direct OEM replacement — no cutting or modification required

This complete kit includes all necessary bushings, sleeves, and related components for a full installation. Prothane polyurethane suspension components are a trusted upgrade for street performance, towing, and off-road applications where suspension integrity is critical.
