Prothane 24-47126 Polyurethane Leaf Spring Eye Shackle Bushing Kit

The Prothane 24-47126 is a premium polyurethane leaf spring eye and shackle bushing kit designed to replace worn or failed OEM rubber bushings in leaf spring suspension systems. In leaf spring suspensions, the pivot points and shackle mounting locations are subjected to significant and repeated stress — making bushing condition critical to handling, ride quality, and load-carrying capability.

OEM rubber bushings deteriorate over time due to road grime, heat cycling, and mechanical wear. Once failed, a leaf spring's effectiveness is severely compromised, leading to a rough ride, reduced towing or load capacity, and diminished vehicle control. Prothane's premium-grade polyurethane material is far more resistant to these forces, delivering a longer service life and more consistent performance compared to factory rubber.

Key Features:

• Premium-grade polyurethane construction — more durable than OEM rubber and resistant to road grime, oils, and environmental wear
• Precision-fabricated sleeves and hardware included for a correct, rattle-free fit
• Restores proper leaf spring pivot and shackle function for improved ride stability and load control
• Includes Prothane Super Grease for proper lubrication at installation to prevent squeaking
• Available in red or black; both colors share the same durometer (hardness) for identical performance — black formulation includes graphite for additional squeak resistance
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship for the life of the original purchaser's vehicle

The Prothane 24-47126 bushing kit is a direct-fit replacement engineered to exacting specifications, ensuring straightforward installation without modification. Proper lubrication with the included grease at the time of install is recommended to maximize longevity and minimize noise.
