The SYN-NSG-R NSG370 Reverse Brass Synchro is a carbon-lined reverse-gear 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
Fitment:
- 2007-2016 Jeep Wrangler JK
- 2007-2016 Jeep Wrangler Unlimited JK
- 2005-2006 Jeep Wrangler TJ
- 2005-2006 Jeep Wrangler Unlimited TJL
- 2005-2007 Jeep Liberty KJ
- 2008-2009 Jeep Liberty KK
