Extremely happy with my billet flex plate 305-900-2104. It's been 2k miles and no problem yet. Will put it to the test when I hook up my 40' 5th wheel. Along with this I installed a remanufactured 5.9 cummins, new transfer case and a remanufactured 48re, among other things. $27k in this ste so far.

Excellent product

Order #1253106. Have a Revmax converter hooked up to this. Making about 800 to the tires. If you turn your truck up and don't go with this product or one that may be stronger you are wasting money because you're going to be ripping a flexplate apart and paying to get it replaced. About $1400 for the flexplate and labor. Buy once, cry once, unlike me. Had another brands billet flexplate and ripped that one.

Heads up until they post it them selves this flex plate will not nate to a DTT torque converter states it right in the installion instructions once you recive it hope this helps some people out and they dont end up like me haveing to wait and return for one that will work. The customer support was great though so far at ressolveing the issue gave it 4 stars beacuse it looked like a very good quality piece

dtt torque converter

This is more of a continue from my last review after talking to ats this flex plate will work with a Dtt converter depending on how old it is according to ats it is the older converters that will have the clearance issue the newer converters will work I had easily a 1/4" of play between my converter and pump but I would call ats to double check and make sure your converter will work.
