Terra Firma Automotive supplies genuine Nissan selective-fit transmission retaining rings that allow precise adjustment of input shaft end play during assembly. This 2.03 mm main drive snap ring is the exact OEM part used to securely lock the front input shaft pilot bearing in the transmission case. Nissan provides multiple thicknesses so builders can achieve the factory-specified clearance and preload for optimal bearing life and smooth operation.
Choosing the correct thickness is critical during transmission rebuilds — the 2.03 mm ring is one of the thicker options commonly needed when measuring end play on higher-mileage or freshly rebuilt gearboxes. It prevents excessive shaft movement that can cause bearing whine, noise, or premature failure while maintaining proper alignment between the engine and transmission.
At Terra Firma Automotive, we stock the full range of these factory selective snap rings so you can complete your Z32 manual transmission work with exact tolerances. Whether you are replacing the input shaft bearing, performing a full gearbox rebuild, or doing a clutch service on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 2.03 mm snap ring ensures everything stays precisely where Nissan intended.
