Prothane 6-1023 Rear Leaf Spring Eye & Shackle Bushing Kit - Red

The Prothane 6-1023 is a premium polyurethane rear leaf spring eye and shackle bushing kit designed to replace worn OEM rubber bushings. In leaf spring suspensions, pivot points and shackles are subject to significant stress — and soft, deteriorated factory rubber bushings allow unwanted flex that leads to poor axle alignment, steering wander, and accelerated tire wear. Prothane's premium-grade polyurethane restores suspension integrity and keeps your axle properly located.

Key Features:

• Premium-Grade Polyurethane Construction — Firmer and more durable than OEM rubber, resisting road grime, salt, and fluids that cause rubber to break down prematurely
• 3-Piece Kit — Includes spring eye and shackle bushings with all related hardware and precision-fabricated sleeves for a direct, perfect fit
• Improved Axle Alignment — Holds its shape under load where rubber would compress and distort, maintaining proper rear axle positioning
• Lifetime Warranty — Backed by Prothane's lifetime warranty against defects in materials and workmanship
• Includes Super Grease — Kit comes with Prothane Super Grease for proper lubrication during installation to ensure quiet, squeak-free operation
• Available in Red or Black — Both colors share the same durometer (hardness) rating and performance characteristics; black formulation includes a small amount of graphite for additional squeak resistance

All sleeves and components are precision-fabricated for an accurate OEM-replacement fit. Proper lubrication of each bushing during installation is essential for long-term, squeak-free performance — use the included Super Grease and apply it thoroughly before pressing bushings into place.
