This is our Billet Steel version of the outer toothed synchro ring for the 1st and 2nd gear “double cone” synchronizer mechanism used in many 911 transmissions 1995-2011 (not 996, Boxster S 1999-2005). It has (6) groups of (6) teeth. It is interchangeable with 950.304.611.20. This is an unlined synchro for use with our double Carbon Fiber-lined Cone Ring (p/n: 534.632.SCF) or the original 950.304.613.20 sintered bronze cone ring. Original part is PM. This is a hardened Steel Billet ring which is much stronger than the original.
