I have a 05 2500 reg cab full size bed with a ZF 6 speed and was wondering if GM changed the clutch and flywheel from previous years, also I want to upgrade the whole assembly to something better. I have a prototype VA box set on 110hp and have no problems yet, but I want to add more power adders to have some fun. If anybody has any info please post.

CPMac is the man to talk to. He has dual disc setups as well as single. Both kits come with a one piece flywheel. Dual disc will handle more power than the Dmax is capable of putting out so far.
