Synchronizers

Download Product Data Sheet

The Synchronizer System is a collection of highly precision engineered set of metal rings that work in tandem within a manual transmission to provide a very smooth engagement of gears as they are “shifted” from one gear to another during the driving process. As the name suggests, these rings “synchronize’ the parts that are spinning at different speeds within the transmission system

Divgi-TTS supplies complete multi-cone steel-based synchronizer systems with carbon lining – single, dual & triple cone – to several leading Indian customers. Recognizing the inherent advantages of steel as a metal for synchronizer rings over brass, Divgi-TTS pioneered the introduction of steel based synchronizer systems in India and currently is the biggest Indian steel synchronizer systems supplier.
