I have been reading everything i can find and cant seem to find the answer im looking for.....How do the new 6.7s with a 3.73 gear respond to larger tires??

I know its going to hurt it but how bad will 37's hurt my acceleration after i lift my truck?

i have riddin in several trucks with larger tires and the different brands seemed to respond much differently.
buddys 6.0 with 38.5's barly lost anything and ran very well.
LLY with 39's was a turd and needed chiped to run almost like stock again,
another lly with 33's still slowed down a great deal and with bully dog Tri dog, intake and exhaust my truck still pulls it up to about 60 then it starts pullin up a bit but not much.
Cousins 06 5.9 with 33's runs better then my 06 did with stock tires

Any expierence?

Thanks

 

I have not driven the 6.7, but from the 5.9s I have driven, I would say with an auto tranny the 37s on a stock truck, you will notice some power loss, especially with the 3.73s. Might even see some accelerated wear and tare with those size tires on a stock Dodge auto tranny, I guess depends on how hard you drive the truck. On the other hand with the 6 spd I think it would be not as noticeable. I could not tell from your sig. which tranny you had, I am assuming it is the auto tho.
