The Story
The SYN-IB6-1 Carbon Synchro 1st or 2nd inner ring Fiesta ST IB6 (14-18) is a carbon-lined 1st-gear synchro from Synchrotech, engineered for Ford 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.
