This is a commonly used and well-documented replacement for USDM 1990–1996 300ZX manual transmissions. While some suppliers label it as “late,” it is fully compatible across the entire Z32 production run and is stocked/sold specifically for USDM vehicles.
Terra Firma Automotive supplies genuine Nissan transmission gears that restore crisp, reliable shifting to your Z32. This 2nd gear assembly is the exact OEM main shaft component engineered for the 5-speed manual gearbox. Precision-machined with the correct tooth profile, synchronizer surface, and material hardness, it ensures smooth engagement into second gear while withstanding the torque demands of both naturally aspirated and twin-turbo engines.
Worn second gears are a frequent issue on Z32 manuals, often causing grinding, notchy shifts, or complete failure to engage under load. This authentic late-style assembly returns positive, quiet gear selection and proper synchro performance, making daily driving and spirited runs far more enjoyable.
At Terra Firma Automotive, we focus on delivering the correct factory transmission internals that keep these legendary gearboxes operating as intended. Whether you’re rebuilding a high-mileage unit, addressing synchro or gear wear, or performing a full refresh on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 2nd gear assembly is a key upgrade for restored shifting quality.
