Prothane 6-1017-BL Leaf Spring Eye & Shackle Bushing Kit - Black Polyurethane

The Prothane 6-1017-BL is a premium black polyurethane leaf spring eye and shackle bushing kit designed to replace worn, deteriorated OEM rubber bushings. Leaf spring suspensions place significant stress on pivot points and shackles, and factory rubber bushings are prone to early failure from wear, road grime, and general use — leaving the suspension loose and imprecise.

Prothane's polyurethane compound delivers a stronger, longer-lasting alternative to OEM rubber. Unlike rubber, polyurethane is resistant to road grime, oils, and the elements, maintaining its shape and performance over time. All related hardware and sleeves are precision fabricated for a direct-fit, no-modification installation.

Key Features:

• Premium-grade black polyurethane construction for superior durability over OEM rubber
• Black color formulation includes a small amount of graphite mixed into the polyurethane, which helps reduce squeaking
• Precision-fabricated sleeves and hardware included for a perfect fit
• Kit includes all spring eye and shackle bushings needed for a complete replacement
• Includes Prothane Super Grease pre-lube — proper lubrication at installation is essential to prevent squeaking
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Prothane polyurethane leaf spring bushings restore suspension integrity and maintain a vehicle's load-carrying capability. Proper greasing of each bushing during installation is strongly recommended to ensure long-term, squeak-free performance.
