Synchrotech Carbon Synchros

UPDATED 3rd gear INNER RING!!! 2-5-2026 We received a new inner ring which fixes the issues with 3rd. If you purchased from us we will send this updated inner ring at no charge. Send us a email with your order number to receive the updated inner ring.

This is hands down one of our favorite upgrades available for the R31/CD/JK transmissions. Carbon synchros dramatically improve shifting response and feel. It greatly reduces the amount of effort needed to row the gears while eliminating the dreaded "lock out" issue, and grinding that is present 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.
