Inline Four is proud to introduce our own 100% full carbon lined racing synchro sets. Branded under the iL4 Performance line, our synchros are OEM manufactured, carbon-lined and not coated, therefore, the carbon material will last longer. Our carbon-lined racing synchros also have all synchros from 1st to 5th lined with carbon. Other brands of synchros currently on the market still use a stock brass 1st and 2nd synchro with only 3rd, 4th and 5th having a carbon coating. Utilizing carbon as the friction material, we were able to achieve full carbon lining on all synchros. Therefore, as the carbon lining acts as a "braking material", gear selection and engagement is smooth, precise and direct. Also, the synchros are durable and able to withstand harsh racing conditions and extreme temperatures.
The iL4 Performance Carbon Lined Racing Synchros are simply awesome and a no-brainer when rebuilding your transmission.
The synchro set includes fully carbon-lined synchros from 1st to 5th. Currently, K-series application only has a 3rd/4th sleeve set that includes carbon-coated 3rd/4th synchro rings.
