Prothane 7-1056-BL Spring Eye & HD Shackle Bushing Kit Black

The Prothane 7-1056-BL is a complete spring eye and heavy-duty shackle bushing kit engineered to replace worn, deteriorated OEM rubber bushings in leaf spring suspensions. Leaf spring suspension pivot points and shackles endure intense, concentrated forces during normal driving — making the condition of these bushings critical to ride quality and handling precision.

Prothane's premium-grade polyurethane compound outperforms factory rubber in every measurable way. Unlike OEM rubber, polyurethane resists breakdown from oils, road salt, ozone, and other environmental contaminants that cause rubber to soften and fail prematurely. The result is a bushing that maintains its shape and firmness over the long term, delivering consistent, predictable suspension response.

Key Features:

• Premium-grade polyurethane construction — resists oils, chemicals, ozone, and road salt
• Heavy-duty (HD) shackle bushings for enhanced strength at high-stress pivot points
• Precision-fabricated components and metal sleeves for an exact, rattle-free fit
• Includes Prothane Super Grease for quiet operation and extended bushing life
• Black color finish
• Available as a complete kit with all necessary hardware included

This kit is the direct polyurethane upgrade over soft, blown-out OEM rubber bushings, restoring proper suspension geometry and improving overall handling feel. All sleeves and hardware are precision fabricated for a correct, confidence-inspiring installation.
