Terra Firma Automotive supplies genuine Nissan selective adjustment shims that enable exact control of counter shaft end play during transmission assembly. This 1.36 mm counter gear bearing shim is the exact OEM spacer used to fine-tune the axial clearance on the counter shaft (layshaft) rear bearing. Precision-ground to Nissan’s tight tolerance, it is one of the thicker options in the selective range, allowing builders to achieve the factory-specified end play for optimal gear alignment and quiet operation.

Proper counter shaft end play is critical in a Z32 manual transmission. Incorrect clearance can produce gear whine, vibration under load, or premature bearing failure. This 1.36 mm shim gives you the necessary thickness to dial in perfect tolerances during a professional rebuild, resulting in smoother power delivery and extended component life.

At Terra Firma Automotive we maintain the full set of these selective shims because they are vital for achieving a factory-accurate transmission rebuild. Whether you are overhauling a high-mileage twin-turbo gearbox, replacing bearings during a refresh, or performing a complete restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1.36 mm counter gear bearing shim is an essential piece for correct internal geometry and reliable long-term performance.
