Synchrotech Carbon Synchros EARLY 5/6gear SET

New product for the R31/CD/JK Nissan transmission!

Carbon synchros dramatically improve shifting performance and feel. They replace the weak factory synchros, which are notorious for causing grinding and lock out during high rpm shifting.

These carbon synchros replace the following OEM synchros. It is recommended to check part numbers in order to confirm fitment. Early R31 transmissions will utilize part number 32604-CD105 for 5th/6th gear synchros. Later transmissions will use part number 32604-5X00A for 5th/6th gear synchros.

  • OEM 1st gear synchro: 32620-CD401 (Triple cone)
  • OEM 2nd gear synchro: 32620-CD008 (Triple cone)
  • OEM 3rd gear synchro: 32620-CD405 (Triple cone)
  • OEM 4th gear synchro: 32620-CD01B (Double cone)
  • Early OEM 5th/6th gear synchro- 32604-CD105 (Single cone)
  • Late OEM 5th/6th gear synchro- 32604-5X00A (Single cone)

    !!We are working on a full application list but you can also use the OEM part numbers to check fitment on your vehicle. Just use a oem Nissan parts website where you can enter your VIN. Then enter each part number in to check fitment. !!
