Nissan Fairlady /300ZX Z32 Manual Transmission Synchro Ring Baulk 2nd (Early)

Terra Firma Automotive supplies genuine Nissan transmission synchro rings that restore smooth and positive gear changes in your Z32 manual gearbox. This 2nd gear baulk synchro ring is the exact OEM friction cone designed to synchronize shaft speeds when shifting into or out of second gear. It features Nissan’s factory-specified conical angle and friction surface for strong yet controlled grabbing action that prevents grinding and allows clean engagement.

2nd gear synchros in the Z32 see heavy use during acceleration and downshifts. When the original ring wears, you’ll notice resistance, grinding, or a notchy feel. This authentic replacement returns crisp, reliable shifts while protecting the gear teeth, hub, and shift fork from accelerated damage. Its precise dimensions ensure it works perfectly with the matching synchronizer hub and keys.

At Terra Firma Automotive we carry these critical synchro components because they make a noticeable difference in how a rebuilt or refreshed transmission feels on the road. Whether you’re doing a full gearbox rebuild on your twin-turbo, addressing shifting issues, or refreshing the internals on a naturally aspirated model, this 2nd gear baulk ring helps bring back the factory shift quality that makes these cars so engaging to drive.
