Nissan Fairlady/300ZX Z32 Rear Final Drive Side Gear Thrust Washer 1.28mm

Terra Firma Automotive supplies genuine Nissan differential adjustment components essential for accurate R200 limited-slip differential setup on twin-turbo Z32s. This 1.28 mm side gear thrust washer is the exact OEM selective shim used to fine-tune side gear clearance and backlash. Precision-ground to Nissan’s tight tolerance, it allows builders to achieve the ideal internal geometry required for smooth operation and maximum durability under the high torque and horsepower output of the VG30DETT engine.

Proper side gear clearance is critical in a performance differential. The wrong thickness can cause clunking during load changes, uneven power delivery, or accelerated wear on the gears and bearings. This authentic 1.28 mm thrust washer provides another key selective option in Nissan’s range, helping achieve factory-specified tolerances during reassembly for quiet and reliable function.

At Terra Firma Automotive we stock the full selection of these selective side gear thrust washers because they are vital for a professional differential rebuild. Whether you are overhauling a high-horsepower twin-turbo rear end, refreshing the internals, or performing a complete differential restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1.28 mm side gear thrust washer helps ensure precise setup and long-term performance.
