Hello, I have a KJ 06 6speed. Just had clutch work done on it. The mechanic told me the flywheel the Liberty uses looked very different from other Jeep flywheels. It is a dual mass fly wheel which feature a space for a built-in damper designed to isolate engine torque spikes and prevent transmission damage. I heard it shouldn’t be used for performance clutches. I just put a new Luk clutch in it. My question has anyone upgraded this flywheel and if so what are the options. What are the reasons limiting this type of flywheel ? Pros or cons?
