I am currently having a new tranny put in and in the process the transfer case is getting a rebuild. New bearings and a clutch pack, now the mechanic who is doing the over haul said he is going to set up my transfer case clutch pack in a drag and circuit sequence. i.e. plate disc plate disc plate disc etc. the factory set up is plate plate disc plate plate disc etc. The factory set up consists of 12 plates and 7 discs, he will install 9 plates and 9 discs, one of the plates will be xtra thick to take up the slack He calls this a transfer case tuning, and says a lot of drag and circuit cars run this set up? I searched the forum and have not found any mention of this at all, unless I am not using the correct key words. Comments and or opinions for this subject.
