Prothane 6-1051 Leaf Spring Eye Shackle Bushing Kit Polyurethane

Prothane's 6-1051 Leaf Spring Eye and Shackle Bushing Kit delivers a significant upgrade over factory rubber bushings in leaf spring suspension systems. In leaf spring-type suspensions, substantial forces are concentrated at the pivot points and shackles — over time, OEM rubber bushings soften, deform, and blow out, leading to sloppy handling, increased body roll, and accelerated component wear.

This kit replaces worn factory bushings with premium-grade polyurethane components engineered to Prothane's exacting standards. Polyurethane resists compression, oil, and road chemicals far better than rubber, maintaining consistent geometry and firmness across a wide range of temperatures and load conditions.

Key Features:

• Premium-grade polyurethane construction for increased durability over OEM rubber
• Resists deterioration from oil, road chemicals, and extreme temperatures
• Precision-fabricated sleeves and hardware included for a perfect, rattle-free fit
• Restores proper suspension geometry and reduces axle wrap
• Improved handling response and reduced body roll compared to stock bushings
• Direct OEM replacement — no modifications required for installation
• All necessary components included for a complete bushing replacement

Prothane polyurethane suspension bushings are manufactured in the USA and are a trusted choice for performance upgrades and restoration projects alike. The 6-1051 kit includes all related sleeves and hardware precision fabricated to ensure a correct, long-lasting fit.
