This is one set of 3 billet keys (as pictured). Each of the synchro assemblies requires one set (3) of keys. These keys will fit the 3-4, 5-6 OR Reverse synchro assemblies. Springs are included, which is why we need to know which synchro assy are purchasing the keys for.
Keys can be used in the 3-4 synchro assembly in T45, T56 & T5 transmissions. Also for the T56 5-6 & Reverse synchro assembly.
Billet keys are a necessary upgrade for high performance and race applications. Replace the weak stamped steel keys with a superior billet material.
