The ST-MTF-4 Synchrotech MTF 4 liter pack is a carbon-lined synchro from Synchrotech, precision-engineered for high-performance 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
