The SG-B136-GS3 GSR 1.36 Ratio Pro Series 3rd Gear Set is a carbon-lined 3rd-gear synchro from Synchrotech, engineered for Honda/Acura B18C GSR & Type R 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.
