Nissan Fairlady/300ZX Z32 Rear Final Drive Side Bearing Shim 2.15mm (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 2.15 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 exact thickness tolerance, it helps achieve the ideal internal geometry required for smooth, quiet operation and maximum durability under the high torque and horsepower of the VG30DETT engine.

Proper side bearing preload is one of the most important factors when rebuilding a performance differential. The wrong shim thickness can cause bearing noise, vibration under load, overheating, or accelerated wear. This authentic 2.15 mm washer provides builders with another critical option in Nissan’s selective range, allowing fine adjustments to reach factory-spec tolerances during reassembly.

At Terra Firma Automotive we stock the full selection of these 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 2.15 mm side bearing shim helps achieve optimal gear alignment and reliable performance.
