Ideal gears for 35's would be 4.56.

So you guys really think that going to 4.11 gears will help the trans out for the long run?

If you keep the 35" tires, go 4.56.

I agree with everyone about 4.56's if you want to keep 35's.They would make your trannies life a lot easier!

If you're keeping the 35's then 4.56's no doubt...I run 33's and 4.10's and almost want to go to 4.56's myself.
