The Story
The SYN-547-R ZF-S5-47 Reverse Carbon Synchro is a carbon-lined reverse-gear synchro from Synchrotech, engineered for Chevy, Ford, GMC 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.
