How are the stock 6R140s holding up when people mod the 6.7 ?

Is anyone towing heavy with a modded 6.7 ? Has the 6R140 complained ?

What is the torque and HP limit of a a stock 6R140 ?

Thanks !

Usually the numbers in the trans name are describing it...6forward, Reverse, and 1400ftpds. This has been the case in the past so I assume its still true.

I agree with this but it also got me thinking....


4R100... 1000 ftlb???

LMAO I almost posted that in my first one but decided against it. We all know they won't do 1k ftlbs. Hell a 7.3 truck won't even make that much.

1400 ftlbs is the torque rating of the clutches after the TC. The TC amplifies the engine torque. So the engine torque will have to be less than 1400 ftlbs.

I love them so far, i have run several sets of these tires in different sizes. My only complaint is i wish they were a tad bit wider....they are a good bit narrower and shorter then toyo mt 37x1350s on my brothers truck.

I am running the stock 3.55 gears in my truck and it seems to handle the tires and the loads very good....much better then my 06 ford with 37s and my 08 chevy with 35s.

believe it or not but i ran these same tires on factory wheels with just a 2" spacer up front.....but it looked like too much tire for the fender with that little lift.....go ahead and get you a carli or do like me and have to piece one together as money comes in lmao!!!
