Prothane U-61075R Rear Differential Mount Bushing - Red Polyurethane

The Prothane U-61075R is a high-performance polyurethane rear differential mount bushing designed specifically for 2006-2007 Mazdaspeed 6 vehicles. This replacement bushing upgrades your stock rubber mount with superior polyurethane material that provides enhanced drivetrain stability and longevity.

Key Features:

• Constructed from durable red polyurethane that resists oil, chemicals, and environmental degradation
• Maintains shape under stress better than original rubber bushings
• Controls torque and eliminates breakage for improved drivetrain alignment
• Metal run-safe interlock feature prevents catastrophic failure
• Made in the USA with Prothane's lifetime warranty

Polyurethane bushings provide firmer support than rubber, reducing differential movement during acceleration and cornering. While slightly increasing vibration transfer compared to stock rubber, the improved throttle response and secure differential positioning make this an excellent upgrade for performance-minded drivers.
