These new Carbon Fiber Lined Billet Steel synchronizer rings are the ultimate in performance and durability for your G50 / G64 type transmission. This synchro ring replaces original p/n: 928.304.211.23 (which is bronze with a molybdenum friction lining). It has two distinct key advantages. First of all, the hardened billet steel body and teeth of our synchro are over twice as strong as the o.e. cast bronze part. Broken teeth and damaged stop cams are a thing of the past. Secondly, our carbon fiber lining, developed in conjunction with a leading o.e.m. supplier, is a much more modern friction material with many advantages over the original moly materials.
Our carbon fiber lining improves the feel and speed of selecting gears, especially at higher RPM where higher braking forces are required for quicker speed-matching. It has high energy capability, high tolerance to abuse and extremely low wear. These fit 3rd – 6th gears in 6 speed transmissions. They will not fit 5 speed transmissions. For 5 speed transmissions see our p/n: 514.210 or 514.215. See Tech Doc. 0916.1 below for further information.
