GKTech Infiniti Nissan Z33 350z/G35 Solid Diff Bushings

The GKTech Solid Differential Bushings for the 350Z and G35 are a direct replacement for the factory rubber diff bushings, eliminating unwanted flex and locking the differential solidly to the subframe. Ideal for high-performance street cars, drift builds, or circuit use, these solid bushings help reduce wheel hop, improve throttle response, and maintain consistent drivetrain alignment under load.

Machined from 6061-T6 billet aluminum, these bushings are built for durability and precision. By removing the soft OEM rubber, you ensure power is transferred directly to the wheels without delay or deflection.

Key Features:
