Prothane 7-1006-BL Black Rear Leaf Spring Eye and Shackle Bushing Kit

The Prothane 7-1006-BL is a complete black polyurethane leaf spring eye and shackle bushing kit designed to replace worn, deteriorated OEM rubber bushings at every pivot point and shackle location in the suspension. In leaf spring suspensions, significant forces are concentrated at these pivot points, making bushing condition critical to handling precision and ride consistency.

Prothane's premium-grade polyurethane outperforms factory rubber bushings by resisting compression, deterioration, and deformation under load. Unlike OEM rubber, polyurethane does not rot or break down when exposed to oils, road salt, chemicals, ozone, or other environmental contaminants — delivering long-lasting performance that rubber simply cannot match.

Key Features:

• Premium-grade polyurethane construction — resists oil, road salt, chemicals, ozone, and UV exposure
• 1-3/8 inch OD frame shackle bushings for precise fitment
• Precision-fabricated metal sleeves included to ensure a perfect, rattle-free fit
• Loaded with super grease to reduce noise and ensure quiet, smooth operation
• Provides necessary rigidity at pivot points to eliminate the vague, mushy response caused by blown-out rubber bushings
• Black finish for a clean, factory-compatible appearance
• Complete kit — includes all bushings, sleeves, and grease needed for installation

Upgrading to Prothane polyurethane bushings restores suspension integrity and improves steering response and handling confidence. All hardware is precision fabricated for a direct-fit installation with no modification required.
