Prothane 6-1145-BL Rear Stabilizer Bar Bushing Kit 21mm 2WD Polyurethane Black

The Prothane 6-1145-BL is a rear stabilizer bar bushing kit designed for 2WD applications, featuring a 21mm bore and manufactured from Prothane's high-performance black polyurethane compound. These bushings are a direct upgrade over the factory rubber bushings that come stock on most vehicles, restoring — and even improving — the effectiveness of your OEM or aftermarket stabilizer (anti-roll/sway) bar.

Key Features:

• Polyurethane construction — significantly firmer than OEM rubber for improved handling response and reduced body roll
• 21mm bore diameter — fits standard rear stabilizer bars on compatible 2WD vehicles
• Grooved inner bore — designed to retain Prothane Super Grease for smooth, quiet, squeak-free operation
• Black (BL) finish — color-coded for easy identification and a clean under-vehicle appearance
• Direct OEM replacement — bolt-in fitment with no modifications required
• Compatible with larger-diameter high-performance aftermarket sway bars as noted by application

Prothane polyurethane bushings resist deterioration from road oils, solvents, and UV exposure far better than stock rubber, ensuring long-lasting performance. Whether you're restoring a worn suspension or building a performance-oriented setup, the 6-1145-BL delivers tighter, more predictable handling without sacrificing daily drivability.
