Prothane 14-1112-BL Rear Sway Bar Bushing Kit 22mm Black Polyurethane

The Prothane 14-1112-BL is a rear stabilizer bar bushing kit designed for the 1984–1989 Nissan 300ZX. Engineered from firm polyurethane, these bushings are a direct upgrade over the factory rubber units, restoring and enhancing the performance of the OEM sway bar (also known as an anti-roll bar or stabilizer bar).

Over time, stock rubber sway bar bushings warp, crack, and lose their grip on the bar, allowing unwanted movement that diminishes the sway bar's ability to control body roll. Prothane's polyurethane compound resists road grime, weathering, and oil exposure that degrade rubber, maintaining a secure, consistent grip on the 22mm sway bar for the life of the vehicle.

Key Features:

• Fits 22mm rear stabilizer bar diameter
• Black polyurethane construction — graphite-infused formulation helps resist squeaking
• Grooved bore design retains supplied Prothane Super Grease for quiet, smooth operation
• Firmer than OEM rubber for improved chassis feedback and reduced body roll
• Resistant to degradation from oil, weather, and road contaminants
• Backed by Prothane's lifetime warranty against defects in materials and workmanship
• Includes Prothane Super Grease for proper installation lubrication

This kit delivers a noticeable improvement in handling response and suspension precision. Proper greasing of the bushing bore at installation is essential for quiet, long-lasting operation.
