Prothane 6-1138-BL Front Sway Bar Bushing 4WD 33mm Polyurethane Black

Upgrade your vehicle's handling and stability with the Prothane 6-1138-BL Front Sway Bar Bushing. Engineered as a direct replacement for worn, soft OEM rubber bushings, this 33mm polyurethane bushing is designed for 4WD applications and delivers a noticeable improvement in sway bar responsiveness and overall suspension performance.

Prothane's firm polyurethane construction dramatically reduces the flex and deflection associated with stock rubber bushings, allowing the stabilizer bar to transfer forces more efficiently and keep your vehicle flatter through corners. Each bushing features a precision-grooved bore designed to retain Prothane's proprietary super grease, ensuring smooth, quiet operation over the long term — eliminating the squeaks often associated with aftermarket polyurethane.

Key Features:

• 33mm inner diameter — designed for OEM and performance sway bars
• Black polyurethane construction — firmer than rubber for improved handling response
• Grooved bore retains Prothane super grease for quiet, long-lasting performance
• Direct OEM replacement — no cutting or modification required
• Resists oil, road chemicals, and weathering better than rubber
• Compatible with 4WD front stabilizer bar applications (1997–2002)
• Sold as a complete bushing kit

Whether you're restoring worn suspension components or looking to sharpen your vehicle's cornering behavior, the Prothane 6-1138-BL is a cost-effective upgrade that outperforms and outlasts factory rubber bushings.
