Prothane 4-1114 Front Sway Bar Bushing Kit 1-1/16" Polyurethane

The Prothane 4-1114 front stabilizer bar bushing kit upgrades the factory rubber bushings on compatible 1976–1989 vehicles with high-performance polyurethane. Polyurethane is significantly firmer than OEM rubber, reducing bushing deflection and improving the responsiveness of the factory anti-roll (sway) bar for better cornering stability and handling precision.

Key Features:

• 1-1/16" bore diameter — fits the factory stabilizer bar diameter on applicable applications
• Grooved bore design — channels are machined into the bore to retain Prothane Super Grease, ensuring quiet, squeak-free operation over the long term
• Polyurethane construction — resists compression, heat, and automotive fluids far better than OEM rubber bushings
• Direct OEM replacement — installs using factory hardware and mounting locations; no modifications required
• Reduces body roll — firmer bushing material allows the sway bar to work more efficiently, minimizing chassis flex under cornering loads
• Long service life — polyurethane maintains its mechanical properties far longer than stock rubber, reducing the frequency of replacement

The Prothane 4-1114 kit is part of Prothane's comprehensive polyurethane suspension line and includes all bushings needed for a complete front stabilizer bar bushing replacement. Compatible with vehicles requiring a 1-1/16" diameter front sway bar bushing from 1976 to 1989. Prothane Super Grease is recommended for installation to ensure optimal performance and quiet operation.
