Prothane 1-804 Rear Frame Shackle Bushing Kit for Jeep Cherokee & Commander 84-99

The Prothane 1-804 is a premium-grade polyurethane rear frame shackle bushing kit designed as a direct upgrade over worn or deteriorated OEM rubber bushings. In leaf spring suspensions, the shackle pivot points are subject to intense and repeated forces — making bushing condition critical to ride quality, handling, and load-carrying capability.

Why Upgrade from Rubber?

OEM rubber bushings mount the leaf spring to the frame, but rubber has a limited service life. Once rubber bushings fail due to wear, road grime, or exposure to oils and chemicals, the leaf spring's ability to absorb road impacts and distribute vehicle load is significantly compromised. Prothane's polyurethane formulation resists deterioration from road grime, oils, and environmental exposure that destroys rubber over time.

Key Features:

• Premium polyurethane construction — stronger and longer-lasting than OEM rubber bushings
• Precision fabricated — includes all necessary sleeves and hardware for a correct, rattle-free fit
• Available in red or black — both colors share the same durometer (hardness) and performance characteristics; black variant contains a small amount of graphite which may help reduce squeaking
• Includes Prothane Super Grease — proper lubrication at installation is essential for squeak-free performance
• Lifetime warranty to the original purchaser against defects in materials and workmanship

Kit includes all bushings and precision-fabricated sleeves required for a complete rear shackle bushing replacement. Lubricate all bushings thoroughly with the included Super Grease during installation for best results and long service life.
