Prothane 12-1601 Rear Differential Housing Mount Bushing Kit for 1990-1997 Mazda Miata

Restore proper rear differential support with the Prothane 12-1601 Differential Housing Mount Bushing Kit, designed for 1990-1997 Mazda Miata applications. This replacement bushing kit uses durable polyurethane construction with steel components to help reduce unwanted differential movement while maintaining reliable driveline alignment. The red polyurethane and cadmium finish provide a distinctive appearance and dependable service for street-driven or performance-oriented vehicles.
Prothane polyurethane bushings are engineered to offer improved resistance to wear, oil, and road-related deterioration compared with many conventional rubber bushings. By helping control differential housing movement under acceleration, deceleration, and shifting, this kit can contribute to more consistent power delivery and reduced driveline flex. It is a practical upgrade for Miata owners seeking sharper drivetrain response without replacing the complete differential housing assembly.
The Prothane 12-1601 kit is intended for direct replacement of the rear differential housing mounts on compatible first-generation Mazda Miata models. Verify vehicle year and application before ordering, as fitment may vary by drivetrain configuration or prior modifications. Professional installation is recommended, and all mounting surfaces and related hardware should be inspected during installation to ensure proper fit and long-term performance.
