Terra Firma Automotive supplies genuine Nissan selective adjustment shims that allow precise control of internal clearances during a Z32 manual transmission rebuild. This 1.28 mm counter gear bearing shim is the exact OEM spacer used to set the axial end play on the counter shaft (layshaft) rear bearing. Ground to Nissan’s exact thickness specification, it helps achieve the ideal factory clearance that keeps the counter shaft stable, quiet, and properly aligned under high torque and sustained RPM.
Achieving the correct counter shaft end play is one of the most important steps in a professional rebuild. Too much play causes gear whine and accelerated wear, while too little can lead to binding and overheating. This 1.28 mm shim provides a thicker option in Nissan’s selective range, giving builders the flexibility to dial in perfect tolerances for smooth, reliable operation.
At Terra Firma Automotive we stock the complete range of these critical shims because they are essential for a high-quality, long-lasting transmission rebuild. Whether you are overhauling a twin-turbo gearbox, replacing worn bearings on a naturally aspirated model, or performing a full restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1.28 mm counter gear bearing shim is a key piece for achieving factory-correct internal geometry and quiet performance.
