Prothane 1-803-BL Front & Rear Frame Shackle Bushing Kit Black

The Prothane 1-803-BL is a front or rear frame shackle bushing kit engineered as a direct-fit polyurethane upgrade for the leaf spring suspension system. In a leaf spring suspension, significant forces are concentrated at the pivot points and shackles, making worn or degraded bushings a common source of sloppy handling and imprecise steering response. This kit replaces the factory rubber bushings with premium-grade polyurethane components designed for improved durability and chassis feedback.

Key Features:

• Premium polyurethane construction — firmer than OEM rubber for improved suspension response and handling precision
• Black finish — color-coded black polyurethane (1-803-BL designation)
• Direct-fit replacement — precision-fabricated sleeves ensure a correct, rattle-free installation
• Resistant to deterioration — polyurethane does not rot or degrade from oils, road salt, ozone, or chemical contaminants
• Non-greaseable design — low-maintenance operation once installed
• Includes grease — kit ships with Prothane Super Grease for proper installation lubrication
• Lifetime durability — outlasts OEM rubber bushings that soften and fail over time

This frame shackle bushing kit is applicable to both front and rear shackle positions, giving you the flexibility to address worn bushings across the suspension in one purchase. Prothane polyurethane components are precision fabricated to ensure a perfect fit with no modification required.
