Prothane 16-1103-BL Rear Sway Bar Bushing Kit 19mm Black Polyurethane

The Prothane 16-1103-BL is a black polyurethane rear sway bar bushing kit sized for a 19mm stabilizer bar. Engineered as a direct performance upgrade over factory rubber bushings, this kit delivers improved chassis response and reduced body roll through Prothane's premium-grade polyurethane compound.

Polyurethane construction resists deterioration from oils, road salt, chemicals, and atmospheric contaminants such as ozone and smog — common causes of failure in OEM rubber bushings. The grooved bore design retains grease for smooth, quiet operation over the long term.

Key Features:

• Material: Premium-grade polyurethane — firmer and more durable than OEM rubber
• Bar Diameter: 19mm
• Color: Black (the -BL suffix denotes black; red version available as 16-1103)
• Grooved bore retains grease for quiet, long-lasting operation
• Precision-fabricated for accurate fitment and consistent performance
• Resists oils, road salt, ozone, and chemical degradation
• Sold as a pair, complete with matching heavy-duty mounting brackets

Replacing worn or soft factory sway bar bushings with the Prothane 16-1103-BL is one of the most cost-effective suspension improvements available, tightening up cornering response and reducing unwanted lateral flex in the stabilizer bar.
