Nissan Fairlady/300ZX Z32 Rear Final Drive Side Bearing Shim 2.45mm (Twin Turbo)

Terra Firma Automotive supplies genuine Nissan differential adjustment shims that allow precise setup of the R200 limited-slip differential on twin-turbo Z32s. This 2.45 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 exact thickness tolerance, it is one of the thicker options in the selective range, helping achieve the ideal internal geometry for smooth, quiet operation and maximum durability under the high torque and horsepower of the VG30DETT engine.

Correct side bearing preload is critical for performance differentials. The wrong shim thickness can cause bearing whine, vibration under load, overheating, or premature wear. This authentic 2.45 mm shim gives builders another essential option to dial in factory-spec tolerances during reassembly, resulting in optimal gear alignment and long-term reliability.

At Terra Firma Automotive we stock the complete selection of these selective side bearing shims because they are vital 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 2.45 mm side bearing shim helps achieve the precise setup these performance differentials demand.
