Prothane 18-803 Rear Frame Shackle Bushing Kit Polyurethane Toyota 4WD

The Prothane 18-803 is a polyurethane rear frame shackle bushing kit designed as a direct replacement for worn factory rubber bushings on Toyota 4WD trucks and SUVs. Prothane's polyurethane formulation delivers significantly greater durability and resistance to oil, grease, and environmental degradation compared to OEM rubber bushings, helping to restore and maintain proper rear suspension geometry.

Key Features:

• Direct factory replacement fit — no cutting or modification required
• Manufactured from Prothane's proprietary polyurethane compound for extended service life
• Resists compression set, oil, grease, and harsh weather conditions
• Restores proper shackle alignment and rear suspension feel
• Reduces unwanted flex and slop in the rear leaf spring shackles
• Improved chassis feedback compared to worn or soft OEM rubber bushings
• Color: Red (Prothane standard)

Prothane includes all necessary hardware and pre-applied or included grease for installation. These bushings are engineered for 4WD applications where suspension durability and consistent handling are critical, making them a popular upgrade for both daily drivers and off-road use.
