Terra Firma Automotive supplies genuine Nissan transmission synchro components that restore the sharp, confident shifting feel these Z32 manuals were known for. This 1st gear baulk synchro ring is the exact OEM friction ring responsible for matching the rotational speed of the 1st gear to the main shaft during downshifts and engaging from a stop. Engineered with Nissan’s specified conical angle, friction material, and molybdenum coating, it provides the precise grabbing action needed for smooth, grind-free engagement even when the gearbox is cold or under heavy load.
First gear is often the first to show wear in Z32 transmissions because of its high torque multiplication and frequent use in stop-and-go driving or aggressive launches. A worn baulk ring leads to that unmistakable grinding, resistance when selecting 1st, or clunky shifts from 2nd to 1st. This authentic replacement brings back the quick, positive synchronization that makes rowing through the gears enjoyable again, while protecting the gear teeth and shift fork from accelerated wear.
At Terra Firma Automotive we focus on delivering the correct factory internals that turn a good transmission rebuild into an outstanding one. Whether you are refreshing the lower gears on a high-mileage twin-turbo, addressing shifting complaints on a naturally aspirated car, or performing a complete synchro overhaul on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this 1st gear baulk ring is a vital upgrade for restoring factory shift quality and durability.
