i an running 37's with 3.73's and the BD triple dog. power is good, but due to my lift i want to run at least 38's. i am happy with the power i have now, but has anyone run 37's with 3.73's and then switched to 4.10's? or has anyone driven the two different setups and can you comment on if it is worth switching? just would hate to spend the $$$ and not really feel any difference. thanks

 

Yes, in your case it would be beneficial!

I had a number for a wrecker with an 05 for parts let me check it out.

You'll definately feel a difference. I'd do it if I had 37s or 38s. I may end up doing it if I get this heavy 5th wheel I'm eyeing...

 

how much af a difference will it make pulling 23000# i mean my trucks works ok with 3:73 but could i keep my egts down easier with 4:10,s

 

I'm not sure about EGTs since you will always be at an overall higher RPM...but I DO know that it will pull off (i.e. on a hill) noticibly better...

4.10's should lower EGT's because now the truck will require les fuel at any given RPM...right?
