The Story
The SF-05-006 Speed Factory B / H / F Series HD Detent Spring Kit is a carbon-lined synchro from Synchrotech, engineered for Honda H22 (Prelude/Accord), Honda/Acura B16 & B18 (cable), Honda/Acura B16A (hydro), Honda/Acura B18B LS, 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.
