SuperPro Street Performance Rear Differential Mount Bushing Kit for 2004-2015 Mazda MX-5 Miata & RX-8 (SPF3404-70K)

Fits 2004-2015 Mazda MX-5 Miata and Mazda RX-8.

The SuperPro SPF3404-70K Street Performance Rear Differential Center Support Bushing Kit is engineered to eliminate the excessive deflection found in factory rubber mounts. By securing the differential housing, this kit reduces movement during rapid load changes—specifically when rolling on and off the throttle. This results in sharper throttle response and more direct control over the vehicle's cornering attitude, as the drivetrain reacts more quickly to driver inputs.

Built for durability and performance, these bushings offer a vastly extended service life compared to the soft OEM components. This kit is ideal for drivers seeking improved drivetrain rigidity without the extreme harshness of full motorsport bushings.
