Prothane 14-1116 Rear Sway Bar Bushing Kit for Nissan 350Z 21mm

The Prothane 14-1116 rear sway bar bushing kit is engineered specifically for 2003+ Nissan 350Z models equipped with 21mm rear sway bars. This performance upgrade replaces the factory rubber bushings with high-durability polyurethane bushings that significantly improve handling response and reduce body roll during cornering.

Key Features:

• Premium polyurethane construction resists crushing and deterioration unlike OEM rubber bushings
• Grooved inner bores designed to retain Prothane's specially formulated super grease for quiet, squeak-free operation
• Firmer bushing material provides enhanced sway bar effectiveness and more predictable handling characteristics
• Direct replacement for factory 21mm rear sway bar bushings—no modifications required
• Includes all necessary bushings and components for complete rear sway bar installation
• Backed by Prothane's limited lifetime warranty

Upgrading to polyurethane sway bar bushings is one of the most cost-effective suspension improvements available, delivering noticeably sharper turn-in response and reduced understeer. The Prothane 14-1116 kit is ideal for street performance, autocross, and track day applications on the Nissan 350Z platform.
