Prothane 4-802 Rear Leaf Spring Eye & Shackle Bushing Kit

The Prothane 4-802 is a premium polyurethane rear leaf spring eye and shackle bushing kit designed as a direct upgrade over worn factory rubber bushings. In leaf spring suspensions, enormous forces are constantly focused on the pivot points and shackle mounting locations. Over time, OEM rubber bushings soften, crack, and deteriorate — leading to excessive suspension slop, poor handling, and accelerated wear on surrounding components.

Prothane's premium-grade polyurethane material is significantly more resistant to road grime, oils, and environmental deterioration than stock rubber, helping restore and maintain proper suspension geometry for years of reliable service. Each bushing is precision-fabricated for an accurate, rattle-free fit, and all necessary sleeves and hardware are included in the kit.

Key Features:

• Premium-grade polyurethane construction — far more durable than OEM rubber
• 1-inch outer diameter rear shackle bushings
• Precision-fabricated sleeves and components included for a perfect fit
• Holds grease for quiet, squeak-free operation — apply supplied pre-lube at installation
• Resistant to road grime, petroleum products, and UV degradation
• Available in red or black (black formulation includes graphite for additional noise reduction)
• Backed by Prothane's lifetime warranty

For best results, apply the supplied Prothane Super Grease thoroughly to each bushing at installation to ensure quiet, long-lasting performance. This kit is a direct bolt-on replacement requiring no permanent modifications.
