Prothane 8-1143-BL Polyurethane Sway Bar Bushing - Kit Black

The Prothane 8-1143-BL is a front and rear polyurethane sway bar bushing kit in black, engineered as a firm, long-lasting upgrade over soft OEM rubber bushings. Polyurethane resists breakdown from road grime, weathering, and oils that degrade stock rubber over time, ensuring a consistent, secure grip on the stabilizer bar throughout the life of the vehicle.

Unlike rubber bushings that deflect under cornering loads and contribute to unwanted suspension geometry changes, Prothane's polyurethane construction maintains its shape under stress. This delivers more accurate steering response, improved body control, and a more communicative road feel — effectively maximizing the performance of your existing OEM sway bar or a larger aftermarket replacement bar.

Key Features:

• Premium-grade polyurethane construction — significantly more durable than OEM rubber
• Grooved bore design holds Prothane Super Grease for quiet, squeak-free operation
• Graphite-infused black polyurethane formulation for additional noise reduction
• Precision-fabricated for exact OEM fitment — no modifications required
• Compatible with larger-diameter high-performance aftermarket sway bars
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Includes Prothane Super Grease for proper lubrication during installation. For best results, apply grease thoroughly to the bushing bore at the time of install.
