Many times, when rebuilding parts of the gear stack, the synchro rings, synchro springs and hubs are all in good condition and the sleeve itself is what needs replacing. Go to the local Honda/Acura dealer and get ready to spend mega bucks on a full synchro-sleeve set. Here lies your answer if you are ever faced with that delimma. Another iL4 first!
Combine these with our "Carbon-Lined" brass synchro rings for a transmission that shifts like butter!
