The Prothane 14-101 is a complete Independent Rear Suspension (IRS) subframe bushing kit engineered specifically for the 1984-1989 Nissan 300ZX. This precision-manufactured kit replaces the factory rubber subframe bushings with high-performance polyurethane bushings designed to eliminate deflection and improve suspension response.

Key Features:

• Complete subframe bushing replacement kit for the 300ZX IRS assembly
• High-performance polyurethane construction for superior durability and longevity
• Significantly reduces subframe movement and wheel hop under hard acceleration
• Improves handling precision and rear suspension feedback
• Maintains proper suspension geometry under load
• Direct replacement for worn factory rubber bushings
• Resists deterioration from oil, road chemicals, and environmental conditions

Upgrading to Prothane polyurethane subframe bushings restores tight, responsive handling characteristics while providing a substantial improvement over stock rubber components. This kit is ideal for both street performance applications and track-focused builds where precise suspension control is critical.
