Nissan Fairlady/300ZX Z32 Rear Final Drive Side Bearing Shim 2.10mm (Twin Turbo)

Terra Firma Automotive supplies genuine Nissan differential adjustment shims that allow precise control over the R200 limited-slip differential in twin-turbo Z32s. This 2.10 mm side bearing shim is the exact OEM selective spacer used to fine-tune side bearing preload and side gear clearance. Precision-ground to Nissan’s tight tolerance, it plays a vital role in achieving optimal gear alignment and smooth operation under the intense torque and horsepower delivered by the VG30DETT engine.

Correct side bearing preload is essential for a quiet, durable differential. The wrong shim thickness can lead to excessive noise, vibration, bearing overheating, or premature wear. This authentic 2.10 mm shim provides builders with one of the key options needed to dial in factory-spec tolerances during reassembly, resulting in smooth power delivery and extended component life.

At Terra Firma Automotive we stock the complete range of these selective side bearing shims because they are critical for a professional differential rebuild. Whether you are overhauling a high-horsepower twin-turbo rear end, replacing bearings and seals, or performing a full differential restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 2.10 mm side bearing shim helps achieve the precise internal setup these performance differentials demand.
