Prothane 6-1018 Leaf Spring Eye Shackle Bushing Kit

The Prothane 6-1018 is a complete leaf spring eye and shackle bushing kit designed to replace worn or deteriorated OEM rubber bushings in leaf spring suspension systems. In leaf spring suspensions, pivot points and shackle connections are subjected to significant lateral, vertical, and torsional forces — making bushing integrity critical to handling precision and ride consistency.

Prothane's premium-grade polyurethane compound offers superior resistance to compression set, petroleum-based fluids, and environmental degradation compared to factory rubber bushings. The result is tighter suspension geometry, reduced axle wrap, and more predictable handling characteristics without sacrificing ride quality.

Key Features:

• Premium polyurethane construction resists wear, oils, and weathering far longer than OEM rubber
• Precision-fabricated sleeves and hardware included for a direct, accurate fit
• Reduces suspension slop and improves handling response at leaf spring pivot and shackle points
• Restores proper suspension geometry by eliminating bushing deflection and compression set
• Complete kit includes all required bushings, sleeves, and related components for a full installation
• Greaseable design (where applicable) for extended service life

The Prothane 6-1018 bushing kit is an ideal upgrade for vehicles that have experienced bushing degradation, excessive suspension noise, or vague handling — delivering a long-lasting, performance-oriented replacement over standard OEM components.
