Prothane 7-804 Polyurethane Leaf Spring Eye & Shackle Bushing Kit

The Prothane 7-804 is a premium 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 stress loads — making the condition of these bushings critical to ride quality, handling, and load-carrying capability.

Prothane's polyurethane compound is a significantly stronger material than factory rubber, resisting road grime, oils, and the everyday wear that causes OEM bushings to crack, soften, and fail prematurely. When factory rubber bushings fail, suspension slop increases, ride quality degrades, and the vehicle's ability to carry or tow a load is compromised. This kit restores proper suspension geometry and firmness.

Key Features:

• Premium-grade polyurethane construction — harder and more durable than OEM rubber
• Resists deterioration from road grime, oils, and environmental exposure
• Precision-fabricated metal sleeves included for a perfect, rattle-free fit
• Includes Prothane Super Grease for proper installation lubrication
• Available in red and black (black formulation includes graphite to help minimize squeaking)
• Backed by Prothane's Lifetime Warranty for the original vehicle purchaser

For best results and to prevent squeaking, apply the included Super Grease thoroughly to all bushings during installation. This kit is a direct, bolt-in upgrade over factory rubber components with no modifications required.
