Prothane 7-1003-BL Leaf Spring Eye and Shackle Bushing Kit Black

The Prothane 7-1003-BL is a complete leaf spring eye and shackle bushing kit engineered to replace worn or deteriorated OEM rubber bushings with premium-grade polyurethane components. In leaf spring suspensions, the pivot points and shackle locations absorb tremendous forces during acceleration, braking, and cornering — making bushing condition critical to handling precision and ride consistency.

Prothane polyurethane outperforms factory rubber by resisting breakdown from oil, road salt, and chemical exposure that cause rubber bushings to soften and deform over time. The result is a firmer, more predictable suspension response and reduced axle wrap under load.

Kit Features:

• Premium-grade polyurethane construction — resists oils, road salt, ozone, and atmospheric contaminants that degrade rubber
• Precision-fabricated metal sleeves — included for a perfect, rattle-free fit
• 1-1/2 inch OD frame shackle bushings — correct sizing for proper spring geometry
• Super Grease included — specially formulated lubricant for quiet, squeak-free operation
• Increased rigidity — improves handling response and reduces axle wrap compared to stock rubber
• Black finish — low-visibility appearance suited for underbody applications

This kit includes all necessary bushings, precision metal sleeves, and Super Grease to complete the installation. All components are precision fabricated for a direct, no-modification fit.
