Prothane 1-1016-BL Greaseable Spring & Shackle Bushing Kit Black Front & Rear Main Eyes

Leaf spring suspensions place enormous stress on pivot points and shackle mounting locations. Over time, factory rubber bushings soften, crack, and fail — leading to sloppy handling, reduced load capacity, and an overall loss of suspension control. The Prothane 1-1016-BL Greaseable Spring and Shackle Bushing Kit replaces worn OEM rubber bushings with premium-grade polyurethane engineered for long-term durability and precise suspension response.

Unlike rubber, Prothane polyurethane does not rot or deteriorate when exposed to oils, road salt, chemicals, or atmospheric contaminants like ozone and smog. The result is a bushing that holds its shape and performance characteristics for the life of the vehicle. The black formulation includes a small amount of graphite blended into the polyurethane to help minimize noise and reduce the potential for squeaking.

Key Features:

• Premium-grade polyurethane construction — resists oils, road salt, ozone, and chemicals that destroy OEM rubber
• Greaseable design — serviceable after installation for long-term performance and squeak prevention
• Front and rear main spring eye coverage — addresses the highest-stress points in the leaf spring system
• Precision-fabricated metal sleeves included — ensures correct fit and proper load transfer
• Black finish with graphite additive — aids in noise reduction and lubricity
• Includes Prothane Super Grease — pre-lube supplied for proper installation lubrication
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the original purchaser's vehicle

Complete kit includes all necessary polyurethane bushings, precision metal sleeves, greaseable hardware, and a tube of Prothane synthetic Super Grease. Proper greasing at installation is essential to prevent squeaking and ensure maximum bushing life.
