Inside most modern gearboxes, the synchros actually have friction material on multiple surfaces inside the gear assembly. They are like this to give the syncro more "stopping power" or in other words, make the gear set stop better for less grinding in between gear shifts.
Hope this helps!
Hello everyone,
Just picked up my first ever Jeep. Its a 2004 KJ 3.7 4x4 sport.
Hoping that I can provide information on fixes/ modifications that I do to the KJ!
