Prothane 14-1101-BL Front Sway Bar Bushing Kit 21mm Black Polyurethane

The Prothane 14-1101-BL is a front sway bar bushing kit engineered to replace the factory rubber stabilizer bar bushings with high-performance polyurethane. Crafted from Prothane's proprietary polyurethane compound, these bushings deliver a firmer, more precise connection between the sway bar and chassis frame — significantly outperforming soft, degradation-prone OEM rubber units.

Key Features:

• Polyurethane construction — resists compression, deformation, and deterioration far longer than OEM rubber
• Grooved bore design — inner grooves are engineered to retain Prothane Super Grease for smooth, quiet, rattle-free operation
• 21mm bar diameter — precisely sized for factory front sway bars on applicable Nissan/Datsun 720 trucks (2WD and 4WD) and Hardbody models from 1980–1986
• Black finish — sleek, low-visibility appearance under the vehicle
• Sold as a pair — includes both driver and passenger side bushings
• Made in the USA — manufactured by Prothane, a division of DEE Engineering Inc.

Upgrading to Prothane polyurethane sway bar bushings reduces body roll, improves cornering traction, and restores steering precision that worn rubber bushings can no longer provide. The result is more confident, responsive handling without sacrificing daily drivability. Installation is straightforward and uses the existing factory mounting hardware.
