Terra Firma Automotive provides genuine Nissan transmission synchro rings engineered to bring back the crisp, positive shifting feel your Z32 manual gearbox was designed for. This late-style 3rd gear baulk synchro ring is the exact OEM friction cone used on later production Z32s. It features Nissan’s updated friction material and cone geometry to quickly match shaft speeds when shifting into or out of third gear, delivering smooth and confident engagement even during aggressive driving or cold starts.
Third gear is one of the most frequently used gears in the Z32, and its synchro ring often wears first, causing grinding, hesitation, or notchy shifts. This authentic late-version replacement restores the factory synchronization performance, reduces noise and wear on the gear teeth and hub, and returns the satisfying mechanical feel that makes these transmissions so enjoyable to operate.
At Terra Firma Automotive we specialize in the correct factory internals that turn a rebuilt transmission into one that feels factory-fresh again. Whether you’re performing a full gearbox rebuild on your twin-turbo, refreshing worn synchros on a naturally aspirated model, or doing a thorough transmission service on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this late-style 3rd gear baulk ring is an essential upgrade for restoring precise shift quality and long-term durability.
