SynchroTech Pro-Series Carbon Synchros
New carbon fiber lining - A Full carbon lining instead of just a coating.
These new synchros have been completely redesigned with a full carbon lining instead of just a coating. We've test several different versions and went back to the drawing board numerous times to make sure we've created the best possible synchro on the market!
This new material is the result of over a year of testing! In fact, during a two month testing period, the prototype synchros were subjected to countless passes with shifts over 10,000 rpms and showed minimal wear and were reinstalled after inspection for continued testing.
Stronger Brass Body - The brass body has been upgraded to a stronger Japanese brass composition.
Improved lock angle - The lock angle was changed from 120 degrees to 110 degrees to aid in higher RPM shifts.
More surface contact - The inner carbon ridges have twice the surface contact (like putting bigger brakes on the gears).
