Prothane 4-1015-BL Leaf Spring Eye and Shackle Bushing Kit Black

The Prothane 4-1015-BL is a black polyurethane leaf spring eye and shackle bushing kit designed to replace worn or deteriorated OEM rubber bushings in leaf spring suspension systems. In leaf spring suspensions, the spring eye pivot points and shackle mounts are subjected to significant and repeated forces — making bushing condition critical to proper handling, axle alignment, and ride quality.

Stock rubber bushings hollow out and degrade over time, allowing the leaf spring to shift and affecting the vehicle's thrust angle and directional stability. Prothane's premium-grade polyurethane material resists compression, road grime, salt, and the elements that break down rubber, delivering a longer-lasting and more precise replacement.

Key Features:

• Premium-grade polyurethane construction — more durable than OEM rubber
• Precision-fabricated for a correct, consistent fit
• Formulated to hold grease for quiet, squeak-free operation
• Provides necessary rigidity at leaf spring pivot points and shackle mounts
• Black finish with graphite-infused polyurethane blend
• All required sleeves and hardware included for complete installation
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

The kit includes all bushings needed for both the spring eye and shackle positions. Apply the included grease or a compatible polyurethane lubricant during installation to ensure quiet long-term performance. Made in the USA.
