Prothane 7-1008-BL Leaf Spring Eye & Shackle Bushing Kit Black 1.75 in.

The Prothane 7-1008-BL is a premium polyurethane leaf spring eye and shackle bushing kit designed as a direct upgrade over worn OEM rubber bushings. Leaf spring suspensions generate significant forces at pivot points and shackles, and factory rubber bushings are prone to deteriorating over time — leading to sloppy handling, excessive body roll, and unpredictable suspension behavior.

Key Features:

• Premium-grade polyurethane construction — significantly more durable than OEM rubber, resisting compression set, rot, and deterioration
• 1.75-inch bushing outside diameter — engineered for proper fit at the spring eye and shackle mounting points
• Precision-fabricated metal sleeves — included to ensure correct alignment and a perfect, rattle-free fit
• Black finish — clean, understated appearance that blends with factory suspension components
• Includes Prothane Super Grease — specially formulated for use with polyurethane bushings to ensure quiet, smooth operation
• Resists oils, road salt, chemicals, and atmospheric contaminants — including ozone and smog that degrade standard rubber
• Made in the USA — manufactured to tight tolerances for application-specific performance

Unlike soft OEM rubber bushings that deflect under load and cause imprecise suspension geometry, Prothane polyurethane bushings maintain consistent alignment for improved handling response and long-term durability. All hardware and grease needed for installation are included in the kit.
