I own mostly built 05-07 6.0 powerstrokes which have been extremely reliable for the most part after studs which I do my own work and familiar with however duramax not so much, but last month I said what the heck ill try Duramax and bought a 2006 LBZ with 131k and so far not bad I have been fairly impressed besides the suspension components but oh well. I want to tow a 20,000 lbs with it this weekend, my 6.0's can pull it no issue but my question is i want to build the Allison in my truck so what is the best clutch kit to buy for good price that can hold i do a lot of heavy towing and I dont want to have to screw around with anything later on or mid trip.
