Nissan Fairlady/300ZX Z32 Rear Final Drive Side Gear Thrust Washer 1.40mm

Terra Firma Automotive supplies genuine Nissan differential adjustment components that allow precise setup of the R200 limited-slip differential on twin-turbo Z32s. This 1.40 mm side gear thrust washer is the exact OEM selective shim used to control side gear clearance and backlash. Precision-ground to Nissan’s exact thickness tolerance, it is one of the thicker options in the selective range, helping achieve optimal gear positioning and smooth power distribution under the high torque demands of the VG30DETT engine.

Proper side gear clearance is critical for differential performance. Incorrect clearance can cause clunking during acceleration or deceleration, uneven torque split, or accelerated wear on the gears and bearings. This authentic 1.40 mm thrust washer provides builders with another important selective option to fine-tune the differential during reassembly for factory-correct tolerances and reliable long-term operation.

At Terra Firma Automotive we stock the full range of these selective side gear thrust washers because they are essential for a professional and durable differential rebuild. Whether you are overhauling a high-horsepower twin-turbo rear end, refreshing the differential internals, or performing a complete restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1.40 mm side gear thrust washer helps ensure precise setup and smooth performance.
