What gears are you running now? Do you have a manual or auto tranny?

Fill out your sig to give everyone a better idea of what your working with.

you can always run 35s with 20s..it still has a very nice cutom look without the affects of really big tires..but on the other hand i love lookin at those big new style 3rd gens so go for it...and you wont have to regear but it would be smart...35 match up with 4.10s...37s match 4.56

I am running 37" BFG AT's. I saw some power loss, but not enough for me to regear. I run the predator on #4 all the time and watch my EGT's, only gets to around 1400 when it shifts to overdrive. Still enough power to spin them when I want to and more than enough to merge and over take most traffic!:thumbsup

Oh yeah, 3.73's and an auto.

They don't measure out 37's, that is how. When I buy new tires, I am getting an MT of some type and will definately have to install the spacers that I have been putting off for over a year now.:thud:

Real 37's will cost a 3.73 auto truck somewhere about 3mpg loss.There is abig difference in size and wt between a bfg37 and say a toyo mt 37.The bfg 37 weighs less than a 35 toyo mt.
