GKTech Infiniti Nissan Z34 370z/G37 Solid Diff Bushings

The GKTech Solid Differential Bushings are a high-performance upgrade for the Nissan 370Z and Infiniti G37, replacing the soft factory rubber bushings with CNC-machined 6061-T6 billet aluminum units. These bushings eliminate unwanted differential movement under load, resulting in improved throttle response, reduced wheel hop, and better power transfer to the rear wheels.

Ideal for high-horsepower or motorsport builds, these bushings keep the diff firmly planted in the subframe—even under aggressive driving, drifting, or track conditions. They’re a direct fit replacement that ensures maximum drivetrain stability with no guesswork.

Key Features:

• Eliminates Diff Flex: Maintains consistent drivetrain geometry under load
