Prothane 26-47077 Polyurethane Leaf Spring Eye Shackle Bushing Kit

The Prothane 26-47077 is a premium-grade polyurethane leaf spring eye and shackle bushing kit designed to replace worn or deteriorated OEM rubber bushings in leaf spring suspension systems. Leaf spring pivot points and shackles are subject to extreme forces under load, making bushing condition critical to ride quality, handling, and load-carrying capability.

OEM rubber bushings mount the leaf spring to the frame, but they have a limited service life. Once rubber bushings fail from wear, road grime, or age, a leaf spring's effectiveness is severely reduced—resulting in a rougher ride, compromised load capacity, and diminished handling control. Prothane's polyurethane compound is a stronger, more resilient alternative that resists road grime and withstands the stresses of daily driving.

Key Features:

• Premium-grade polyurethane construction for superior durability over OEM rubber
• Available in red or black — both share the same durometer (hardness) for identical performance
• Black formulation includes a small amount of graphite to further reduce the potential for squeaking
• All related sleeves and hardware are precision-fabricated for a perfect, OEM-quality fit
• Includes Prothane Super Grease — proper lubrication at installation is essential to prevent squeaking
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship for the life of the original purchaser's vehicle

For best results, apply the included Super Grease liberally to all bushing surfaces during installation. Proper lubrication is the most effective way to prevent noise after installation. This kit is precision engineered to ensure correct fitment with no modifications required.
