Prothane 6-1017 Leaf Spring Eye Shackle Bushing Kit Polyurethane

The Prothane 6-1017 is a premium polyurethane leaf spring eye and shackle bushing kit designed to replace worn, soft, or deteriorated OEM rubber bushings in leaf spring suspension systems. Leaf spring suspensions generate substantial forces at pivot points and shackle locations, making high-quality bushing material critical for maintaining proper handling, alignment, and ride quality.

Prothane's premium-grade polyurethane compound delivers superior resistance to compression, tearing, and environmental degradation compared to factory rubber bushings. The result is improved suspension response, reduced flex, and longer service life—even under demanding towing, hauling, or off-road conditions.

Key Features:

• Manufactured from Prothane's premium-grade polyurethane for enhanced durability over OEM rubber
• Replaces soft, blown-out factory rubber bushings at leaf spring eye and shackle pivot points
• Precision-fabricated sleeves and hardware included for a correct, rattle-free fit
• Resists oil, grease, road salt, and other environmental contaminants
• Helps restore proper suspension geometry and reduce unwanted axle movement
• Direct OEM replacement design—no drilling or modification required

All necessary hardware, including precision-fabricated sleeves, is included in the kit to ensure a complete and accurate installation. The Prothane 6-1017 is an ideal upgrade for vehicles experiencing sloppy handling, clunking noises, or visible bushing wear in the leaf spring assembly.
