Hi Guys;

I searched around to make sure this hasen't been asked before without success. I am in the oricess of swapping up my rear end ratio from 3:55 to 3:80's to accomodate a lift and tires. This may seem like an odd question, but would I not need to up the Dana 44 ratio on the front end as well. If someone can shed some light on this I would appriciate it.

Thanks.

 

YES. You need to keep both ratios within 1% of each other, otherwise you'll tear up the drivetrain (probably the transfer case will go first).

The one exception to this is if you ONLY drive it on sloppy surfaces. I hear swamp racers run different ratios. Any contact with a high-traction surface when you have different ratios will start causing damage.

Awesome response. Thanks very much. It seemed like a no brainer but I had not seen any previous conversations on the subject.

Thanks again.

 

If u havent allready bought yur gears, there is some web site that will tell u what gear ratio to use w/ what size tire....I found it on here one time, do some searching, because it sounds like yur up grade is'nt enough,

 

I know for 4:10 you need a larger carrier for front 3:80 I don't know . I go 4:10 for 33" but I live in hilly area . Brings RPMS back to norm for the 3:55's Good luck on swap . doing a 3:08 to 3:55 right now for friend

 

What size tires are you going to run??
