Prothane 1-1111-BL Front Sway Bar Bushing Kit 30.5mm Black Polyurethane

Upgrade your Jeep TJ's front suspension performance with the Prothane 1-1111-BL Front Sway Bar Bushing Kit. These 30.5mm black polyurethane bushings are a direct replacement for the factory rubber sway bar bushings, delivering noticeably firmer response, improved handling, and longer service life.

OEM rubber stabilizer bar bushings deteriorate over time, becoming soft and compliant — leading to excessive body roll and sloppy cornering feel. Prothane's polyurethane compound resists compression set, oil, and weathering, keeping your sway bar (also called an anti-roll bar or stabilizer bar) firmly located for consistent, predictable performance on and off road.

Key Features:

• 30.5mm bore diameter — precise fitment for factory front sway bar diameter
• Grooved bore design — engineered to retain Prothane Super Grease for smooth, quiet operation
• Black polyurethane construction — superior durability and resistance to oils, solvents, and UV compared to OEM rubber
• Firm, performance-oriented compound — reduces body roll and improves steering response
• Direct OEM replacement — no modifications required for installation
• Also compatible with larger-diameter high-performance aftermarket sway bars

Each kit includes the polyurethane bushings and is designed for straightforward installation using standard hand tools. For best results and quietest operation, apply the included or recommended Prothane Super Grease to the grooved bore before installation.
