Prothane 7-1003 Leaf Spring Eye Shackle Bushing Kit Polyurethane

Prothane's 7-1003 Leaf Spring Eye and Shackle Bushing Kit replaces worn, deteriorated OEM rubber bushings with premium-grade polyurethane components engineered to outlast and outperform the factory originals. Leaf spring suspensions place intense stress on pivot points and shackle mounts—the critical connection between your spring and chassis—making bushing quality essential to ride quality, handling, and load-carrying capacity.

Prothane's polyurethane construction resists road grime, oil, and the wear that causes rubber bushings to fail prematurely. Once OEM rubber bushings degrade, the leaf spring's effectiveness is severely compromised. These polyurethane replacements maintain proper rigidity and geometry at the mounting points, restoring suspension performance and keeping your vehicle carrying loads confidently.

Key Features:

• Premium-grade polyurethane construction for superior durability over OEM rubber
• Features 1-1/2 in. OD frame shackle bushings
• Precision fabricated components for a perfect, OEM-accurate fit
• Resistant to road grime, chemicals, and environmental degradation
• Includes Prothane Super Grease for proper lubrication during installation
• Available in red or black (same durometer/hardness — black version includes graphite additive to aid in quiet operation)
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

For best results, apply the included Super Grease generously to each bushing at installation to ensure quiet, long-lasting operation. All necessary sleeves and hardware are included for a complete, professional installation.
