The SYN14A Carbon Synchro B/D/H (50MM) is a carbon-lined synchro from Synchrotech, engineered for Honda D15 & D16, Honda H22 (Prelude/Accord), Honda/Acura B16 & B18 (cable) 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
Backed by Synchrotech quality and shipped fast from Speedzone Performance.
