Nissan Fairlady/300ZX Z32 Rear Final Drive Side Gear Thrust Washer 0.89mm

Terra Firma Automotive supplies genuine Nissan differential adjustment components that enable precise internal setup of the R200 limited-slip differential in twin-turbo Z32s. This 0.89 mm side gear thrust washer is the exact OEM selective shim used to control side gear clearance and backlash. Precision-ground to Nissan’s tight tolerance, it is one of the thinner options in the selective range, allowing experienced builders to achieve optimal gear positioning and smooth operation under the intense torque and horsepower produced by the VG30DETT engine.

Proper side gear clearance is critical for differential performance and longevity. Incorrect clearance can cause clunking during acceleration or deceleration, uneven power delivery, or accelerated wear on the gears and bearings. This authentic 0.89 mm thrust washer provides builders with a key selective option to fine-tune the differential during reassembly for factory-correct tolerances and quiet, reliable function.

At Terra Firma Automotive we stock the complete selection 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 full restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 0.89 mm side gear thrust washer helps achieve precise setup and long-term performance.
