SuperPro Rear Differential-to-Subframe Mount Bushing Kit for 2003-2020 Nissan 350Z/370Z and Infiniti G35/G37 (SPF3856K)

Fits select 2003-2020 Nissan 350Z, 370Z and Infiniti G35, G37 models.

The SuperPro SPF3856K Rear Differential-to-Subframe Mount Bushing Kit is engineered to replace the soft factory rubber units that connect the differential to the rear subframe. In Z and G chassis vehicles, OEM bushings are a known failure point; they soften and tear over time, leading to excessive differential movement, drivetrain slop, and audible clunking during gear changes or aggressive throttle application.

This kit restores drivetrain precision by more accurately locating the differential under load. Unlike generic polyurethane upgrades that can introduce harshness, SuperPro's proprietary material is designed to maintain factory-level NVH (Noise, Vibration, and Harshness) isolation, ensuring cabin comfort remains at OEM levels while performance is significantly enhanced. These bushings are resistant to oils, chemicals, and thermal degradation, providing a service life that far outlasts natural rubber components.
