The SYN-CD105 (EARLY MODELS) 5/6th carbon synchro G35/350Z/G37/370Z (R31/CD/JK) is a carbon-lined 5/6th-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
- 09/2004'-2008' 350Z
- 09/2004'-2008' G35
- 2009'-09/2012' 370Z
- 2008'- 03/2013' G37
Replaces OEM part number: D105
