Prothane 14-1106-BL Polyurethane Front Sway Bar Bushing Kit 20mm Black

The Prothane 14-1106-BL is a front stabilizer bar bushing kit engineered for Nissan 4WD Hardbody (D21) trucks with a 20mm (0.787") sway bar. Molded from premium-grade black polyurethane, these bushings deliver a significant handling upgrade over soft, worn OEM rubber components that flex and deform under load.

Key Features:

• 20mm bore diameter — precision-fit for factory Nissan D21 4WD front stabilizer bars
• Black polyurethane construction — resists deterioration from road grime, oils, and weather far better than rubber; includes a small amount of graphite to further reduce the potential for squeaking
• Grooved inner bore — engineered to retain Prothane Super Grease for smooth, quiet operation over the life of the bushing
• Includes Prothane Super Grease — apply during installation to lubricate the bore and prevent noise
• Lifetime warranty — Prothane guarantees these bushings against defects in materials and workmanship for as long as the original purchaser owns the vehicle

Upgrading to polyurethane sway bar bushings restores and improves the effectiveness of the factory anti-roll bar by eliminating the flex and slop associated with aged rubber. The result is reduced body roll, improved cornering stability, and a more responsive feel — comparable to fitting a larger diameter sway bar at a fraction of the cost. These bushings are a direct-fit replacement and are also compatible with larger-diameter high-performance aftermarket sway bars.
