This is our Billet Steel version of the outer toothed synchro ring for the 1st and 2nd gear “double cone” synchronizer mechanism used in 911 (996) and Boxster S transmissions 1999-2005. It has (6) groups of (7) teeth. It is interchangeable with 996.304.611.00. This is an unlined synchro for use with our double Carbon Fiber-lined Cone Ring (p/n: 534.632.SCF) or the original 950.304.613.21 sintered bronze cone ring. Original part is PM. This is a hardened Steel Billet ring which is much stronger than the original.
