Nissan Fairlady/300ZX Z32 Rear Final Drive Side Bearing Shim 2.35mm (Twin Turbo)

Terra Firma Automotive supplies genuine Nissan differential adjustment shims that enable precise setup of the R200 limited-slip differential on twin-turbo Z32s. This 2.35 mm side bearing shim is the exact OEM selective spacer used to control side bearing preload and side gear clearance. Precision-ground to Nissan’s tight tolerance, it serves as an important mid-range option in the selective series, allowing builders to achieve the ideal internal geometry for quiet operation and maximum durability under the demanding torque loads of the VG30DETT engine.

Correct side bearing preload is critical for performance differentials. Using the wrong thickness can lead to bearing noise, vibration, overheating, or accelerated wear on the gears. This authentic 2.35 mm shim provides builders with another precise option to fine-tune the differential during reassembly for optimal gear alignment and long-term reliability.

At Terra Firma Automotive we stock the full range of these selective side bearing shims because they are vital for a professional and long-lasting differential rebuild. Whether you are overhauling a high-horsepower twin-turbo rear end, replacing bearings and seals, or performing a complete differential restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 2.35 mm side bearing shim helps achieve the precise setup these performance differentials require.
