Prothane 17-1001-BL Leaf Spring Eye & Shackle Bushing Kit Black (OEM Shackles)

The Prothane 17-1001-BL is a premium-grade polyurethane leaf spring eye and shackle bushing kit designed as a direct upgrade over worn OEM rubber bushings. Engineered for use with OEM shackles, this kit addresses one of the most stress-intensive areas of a leaf spring suspension system — the pivot points and shackle mounting locations.

OEM rubber bushings are prone to deterioration from road grime, heavy loads, and general wear. Once they fail, suspension effectiveness is severely reduced, resulting in a rough ride, diminished load-carrying ability, and decreased handling control. Prothane's polyurethane material provides far greater resistance to these conditions, delivering lasting performance where factory rubber falls short.

Key Features:

• Premium polyurethane construction — resists road grime, oil, and wear far better than OEM rubber
• Black color with graphite additive — the graphite-infused formulation helps reduce the potential for squeaking
• Same durometer as red Prothane bushings — identical hardness and performance characteristics
• Precision-fabricated sleeves included — all related hardware is machined to exact tolerances for a correct fit
• Includes Prothane Super Grease — supplied lubricant is essential for proper installation and squeak-free operation
• Designed for OEM shackles — compatible with stock factory shackle hardware
• Lifetime warranty — backed by Prothane's warranty against defects in materials and workmanship for the life of the vehicle with the original purchaser

Proper lubrication of each bushing with the included Super Grease during installation is critical to ensure quiet, long-lasting operation. For best results, apply grease thoroughly to all bushing surfaces before pressing into place.
