Nissan Fairlady/300ZX Z32 Rear Final Drive Side Bearing Shim 2.00mm (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 2.00 mm side bearing shim is the exact OEM selective spacer used to control the preload and position of the differential side bearings. Precision-ground to Nissan’s exact thickness tolerance, it helps achieve the ideal side gear clearance and bearing preload required for smooth, quiet operation and maximum durability under the high torque output of the VG30DETT engine.

Proper side bearing preload and clearance are critical in a performance differential. Incorrect shim thickness can cause excessive noise, vibration, bearing overheating, or accelerated wear. This authentic 2.00 mm shim provides one of the key options in Nissan’s selective range, giving builders the ability to fine-tune the differential for optimal gear mesh and long-term reliability.

At Terra Firma Automotive we stock the full range of these selective side bearing shims because they are essential 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 2.00 mm side bearing shim is a vital piece for achieving factory-correct setup and smooth power delivery.
