Prothane 6-1147BL Rear Sway Bar Bushing 25mm Polyurethane Thunderbird 1989-1997

The Prothane 6-1147BL is a premium black polyurethane rear stabilizer bar bushing designed as a direct upgrade over the factory rubber bushing. Engineered for the Ford Thunderbird, this 25mm bushing delivers improved handling precision and chassis rigidity that OEM rubber components simply cannot match over time.

Prothane's polyurethane formulation resists compression, deterioration, and deformation far better than stock rubber, helping to reduce body roll, improve cornering stability, and restore tight, responsive suspension feel. The black polyurethane compound is precision-molded for an exact OEM-style fit with no trimming or modification required.

Key Features:

• 25mm inner diameter — precisely sized to fit the factory rear sway bar
• Premium grade polyurethane construction — resists oil, ozone, and road chemicals
• Infused grease ports — retain super grease for quiet, squeak-free operation
• Provides necessary rigidity — reduces body roll and improves handling response
• Precision fabricated — ensures perfect fit for direct OEM replacement
• Black (BL) finish — maintains a clean, factory-correct underbody appearance

Prothane polyurethane suspension components are a trusted performance upgrade for enthusiasts looking to restore or enhance the handling dynamics of their vehicle. This bushing is a straightforward replacement that can be installed with basic hand tools.
