Terra Firma Automotive supplies genuine Nissan selective adjustment shims that allow precise control of counter shaft end play during transmission assembly. This 1.04 mm counter gear bearing shim is the exact OEM spacer used to fine-tune the axial clearance on the counter shaft (layshaft) rear bearing. Manufactured to Nissan’s strict thickness tolerance, it helps achieve the ideal factory-specified end play for smooth, quiet operation and maximum bearing life under the demands of both naturally aspirated and twin-turbo engines.
Proper counter shaft end play is vital in a Z32 manual transmission. Incorrect clearance can cause gear whine, vibration, premature bearing failure, or excessive noise under load. This 1.04 mm shim provides one of the key thickness options needed during a professional rebuild to dial in perfect tolerances and ensure long-term reliability.
At Terra Firma Automotive we stock the full range of these selective shims because they are critical for a high-quality transmission rebuild. Whether you are overhauling a high-mileage twin-turbo gearbox, replacing bearings on a naturally aspirated model, or performing a complete restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1.04 mm shim is an essential piece for achieving factory-correct internal geometry.
