Prothane 18-1103-BL Sway Bar Bushing Polyurethane Black - 19mm

The Prothane 18-1103-BL is a polyurethane stabilizer bar bushing set designed as a direct replacement for worn or soft OEM rubber bushings. Engineered for 19mm sway bars on 1979–1988 Toyota 4WD and 4Runner applications, these bushings restore and improve suspension performance by eliminating the flex and deflection common with stock rubber components.

Prothane's polyurethane compound is significantly firmer than OEM rubber, resulting in more precise handling, reduced body roll, and a more responsive feel. Each bushing features a grooved inner bore designed to retain Prothane's included super grease, ensuring quiet, squeak-free operation over the long term.

Key Features:

• 19mm inner bore diameter — direct fit for OEM-sized stabilizer bars
• Grooved bore retains grease for reduced friction and quiet operation
• Firm polyurethane construction reduces body roll and improves handling
• Resistant to oils, solvents, and weathering — outlasts OEM rubber bushings
• Black finish; includes Prothane super grease
• Also compatible with larger-diameter high-performance aftermarket sway bars (where applicable)

Prothane polyurethane suspension bushings are a popular upgrade for off-road and street-driven Toyotas, delivering improved stability and durability over the factory rubber bushings they replace. Compatible with OEM part cross-references for the applicable Toyota 4WD/4Runner platform.
