I am running the luk replacement right now and it has been slipping for over a year. Nothing against south bend, I just like to try different things than the norm. Zoom has clutches for all diesel truck models, organic and ceramic discs.
You know what it will eventially be for house. Priorities change in life and things get put on hold for a while. So for now it must remain a street driving trailer puller that doesnt have any problems. 2k is a lot to swallow for a DD pulling clutch.
