Product Description

The Superpro SPF3849K Rear Differential Mount Bush Kit upgrades the rear differential to subframe connection on a range of Nissan Z and Infiniti vehicles. OEM rubber bushings can wear prematurely, leading to excess movement under acceleration and braking. This kit replaces those soft components with engineered polyurethane bushings that deliver improved drivetrain stability, better throttle response, and reduced wheel hop for spirited driving or everyday use.

Designed specifically for RWD 350Z, 370Z, and Infiniti G‑series coupes (G25/G35/G37), the SPF3849K maintains optimal differential alignment while still providing vibration cushioning. Installation typically involves replacing the rear differential mount bushings with the included components and should be followed by a brief road test to confirm performance gains. Fitment is confirmed through model year 2020. Coverage for 2021-2025 is unconfirmed at time of listing and may vary by chassis or trim; always verify with your VIN or manufacturer fitment guide before installation.

*Parts are for USA spec vehicles, please contact us to verify fitment on JDM & international models.
