Terra Firma Automotive supplies genuine Nissan transmission hardware that keeps internal components securely locked in place. This retaining pin is the exact OEM roll pin used in critical areas of the Z32 manual gearbox, most commonly to secure shift forks, detent components, or rail assemblies. Manufactured to Nissan’s precise diameter, length, and hardness specifications, it provides reliable shear strength and positive locking that prevents movement or dislodging under the repeated stress of shifting and high torque loads.
These small retaining pins are vital but often overlooked until they shear, work loose, or are lost during a rebuild. A missing or damaged pin can cause sloppy shifting, missed gears, or even complete shift fork failure. This authentic replacement restores solid mechanical retention, ensuring every shift feels tight and predictable while protecting more expensive components like forks, rails, and synchros from accelerated wear.
At Terra Firma Automotive we carry these factory hardware items because they are essential for a correct and durable transmission rebuild. Whether you are deep inside a gearbox on your twin-turbo, refreshing the shift mechanism on a naturally aspirated model, or completing a full transmission overhaul on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this retaining pin helps maintain the precise factory assembly and long-term reliability these cars are known for.
