Terra Firma Automotive supplies genuine Nissan transmission shafts that maintain proper gear alignment and long-term durability in your Z32 manual gearbox. This reverse idler shaft is the exact OEM support shaft that the reverse idler gear spins on. Precision-ground to Nissan’s tight tolerances with the correct diameter, length, and surface finish, it ensures the reverse idler gear rotates smoothly and stays perfectly aligned with the main shaft and countershaft for clean reverse engagement.

A worn or damaged reverse idler shaft often causes grinding when selecting reverse, excessive noise, or difficult engagement. This authentic replacement restores the proper support and alignment the gearbox needs, eliminating play in the reverse system and reducing wear on the idler gear and synchro components.

At Terra Firma Automotive we focus on these critical but hard-to-find internal transmission parts that make a real difference during rebuilds. Whether you are fully rebuilding a noisy gearbox on your twin-turbo, replacing a damaged reverse assembly on a naturally aspirated model, or completing a thorough transmission overhaul on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this reverse idler shaft returns the reverse system to factory specifications.
