Hey everyone,

Let me start off by saying I am a Dana 30 up front Dana 44 rear. I am thinking about going to 37's. If I installed 5.13 on my 2dr with 35" km2's until I can get my 37's. Would that be overkill? Also, is it ok to be running 5.13's in a d30? I hear that the gear gets really small and can fail? My last question is, do I really need 5.13's with a 2dr? I am lighter than a 4dr. Thoughts?

Thanks!

Sean

 

You might have already seen this, but just in case:

 

Ya. I had seen that. But I guess my main question is can a d30 handle a 5.13 gear? And is that ok for 35&37?

 

Depends on your usage. Lots of people are running 5.13's with no issues, but if you have a heavy foot or like to spin tires or get stupid in the rocks, you might consider a beefier axle or dropping down a ratio or two.

 

I have a desire of rapid acceleration on the pavement. But on trails I'm a crawler

 

So according to that chart, with my manual tranny and 35's, my best all around bet is to go with 4.56 for DD and mild trail use?

 

And I'm automatic.

 

I have the same set up
beefy d 30 and 35s
I'm getting 4:88 w/ a 6 speed.

 

4.88 with 6 equals 5.13 with auto?

 

Thats what I have been told. But it also gives you a little extra meat on the gears.
