Prothane 14-1003 Rear Leaf Spring Eye Shackle Polyurethane Bushing Kit

The Prothane 14-1003 is a complete rear leaf spring eye and shackle bushing kit, engineered as a direct upgrade over worn or deteriorated OEM rubber bushings. In leaf spring suspension systems, the pivot points and shackle mounting locations absorb significant forces with every mile driven — making quality bushing material critical to handling, load capacity, and long-term durability.

Prothane's premium-grade polyurethane outperforms factory rubber in every meaningful way. Unlike OEM rubber, polyurethane resists degradation from road grime, oils, road salt, ozone, and other environmental contaminants, ensuring the bushings maintain their integrity over the life of the vehicle.

Kit Contents & Features:

• Premium-grade polyurethane construction — resists oils, chemicals, road salt, and atmospheric contaminants
• Complete kit — includes all necessary bushings, precision-fabricated metal sleeves, and a tube of Prothane Super Grease for proper lubrication
• Precision fabrication for a correct, rattle-free fit
• Provides necessary rigidity at leaf spring pivot and shackle mounting points
• Available in red or black — both are the same durometer (hardness) and will perform identically
• Lifetime warranty — Prothane guarantees all suspension parts to be free of defects in materials and workmanship for as long as the original purchaser owns the vehicle

Proper lubrication at installation is essential. Apply the included Prothane Super Grease to each bushing during installation to ensure quiet, squeak-free operation. This kit includes everything needed for a complete rear leaf spring bushing refresh.
