Prothane 14-1002 Rear Leaf Spring Eye and Shackle Bushing Kit 4WD

The Prothane 14-1002 is a complete rear leaf spring eye and shackle bushing kit engineered for 4WD applications. Leaf spring suspensions place significant stress on pivot points and shackle mounting locations — over time, factory rubber bushings compress, crack, and lose their ability to properly control spring movement. This kit replaces those worn OEM rubber components with precision-molded, premium-grade polyurethane bushings that restore suspension integrity and improve overall handling response.

Prothane's polyurethane compound is substantially firmer than stock rubber, providing more precise spring control under load while resisting deterioration from road grime, oils, and the elements that quickly degrade OEM bushings. All metal sleeves and hardware included in the kit are precision-fabricated to ensure a correct, rattle-free fit.

Kit Includes:

• Rear spring eye bushings
• Rear shackle bushings
• Precision metal sleeves (inner diameter and outer diameter sleeves)
• Prothane Super Grease lubricant packet

Key Features:

• Premium-grade polyurethane construction — firmer than OEM rubber for improved load handling
• Resists road grime, petroleum products, and weathering
• Precision-fabricated sleeves for exact OEM fitment
• Sold as a complete kit — everything needed for installation included
• Red polyurethane color (standard)
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship for the life of the original purchaser's vehicle

Apply the included Super Grease thoroughly to all bushing surfaces during installation to ensure smooth operation and prevent squeaking. For additional grease, Prothane Super Grease is available separately.
