Prothane 4-1010-BL Leaf Spring Eye & Shackle Bushing Kit - Black Polyurethane

Prothane's 4-1010-BL Leaf Spring Eye and Shackle Bushing Kit delivers a significant upgrade over factory rubber bushings in leaf spring suspension systems. Leaf spring pivot points and shackles are subjected to intense forces during acceleration, braking, and cornering — making the condition of these bushings critical to handling precision and suspension longevity. Prothane's premium-grade black polyurethane formulation resists compression set, tearing, and deterioration far better than the soft OEM rubber it replaces.

Key Features:

• Made from premium-grade polyurethane for superior durability over OEM rubber
• Resists oil, grease, road chemicals, and environmental degradation
• Reduces suspension slop and improves steering response and axle tracking
• Precision-fabricated sleeves and hardware included for a perfect, rattle-free fit
• Black (BL) color finish for a clean, finished appearance
• Direct OEM replacement — no modifications required for installation
• Complete kit includes all bushings, sleeves, and related components

Prothane polyurethane bushings are engineered to restore and improve upon the original suspension geometry, providing tighter handling, improved load capacity, and a longer service life compared to factory rubber components. An ideal solution for worn, cracked, or collapsed leaf spring bushings.
