DESIGNED FOR DURABILITY
IAG’s STI 6 Speed Synchro Gear Set features dual carbon friction surfaces. This not only extends the life of the synchro sleeve and gear teeth but also allows for faster and more precise shifting. The IAG Synchros are made from Japanese brass, which is known for durability and its ability to be intricately machined. Our Carbon Faced Brass Synchro Set is precision machined, providing an enhanced shift feel and less wear between moving parts.
