The MK-SYN111B-D15 Brass Master Kit (35mm) D15 L3 S20 (89-95) is a carbon-lined synchro from Synchrotech, engineered for Honda D15 & D16 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.
