The SYN-CD01B 4th gear dual-cone carbon synchro G35/350Z/G37/370Z (R31/CD/JK) is a carbon-lined 4th-gear synchro from Synchrotech, engineered for Nissan transmissions. Carbon friction material grips faster and wears longer than factory brass, delivering smoother, more consistent shifts under hard use — on the street, strip, or track.
Why upgrade to carbon synchros:
- Faster, smoother engagement and reduced grind
- Superior heat and wear resistance vs. OEM brass
- Ideal for high-horsepower, high-RPM and track use
- Direct-fit replacement — no transmission modification required
Fitment:
- R31/CD/JK Nissan transmissions
Replaces OEM part number: 32620-CD01B
