Just wondering if anyone here is running stock gears with 37's or bigger. I just got a free set and have a 3 inch body lift sittin here so i am contemplating on using them. I have stock gears but it is a sport so it has the 4.10's. I also have cold air, fastman 50mm, hypertech programmer, and shorty headers. Do you think it would push the 37's ok or should i re-gear?

 

i been running 37s with 4.10s for a few months but i got my truck at the shop now getting 4.88s put in

it will pull them but dont look for the get up that your used to its like driving a s-10 or something like that just baby it until you get it regeared to keep from going thru a trans or something

it does have enough get up to spin them in the mud but i would definately regear

 

4.10s would work but 4.88s would be quite a bit better. Run them for now then save up for the 4.88s!

 

do you know what your rpms are at around 70mph with the 4.88's and 37's?
