Title: gear change D30&D35 ???
Post by: FullMetalJeep on April 23, 2009, 04:36:03 PM

I know gear ratio below 3.55 in the D35 requires a new case when you go above 3.55.... so what about the dana 30? right now i want to go to at least a 4.88 from my crappy current 3.05 (thanks again Chrysler), unless i decide to swap axles.

i believe the carrier has to be changed out with gears over 3.73 in the D30. I know I had to get a new carrier for my 4.56 gears, I just can't remember where the stock carrier limit is.
Can anybody else confirm?

I'm pretty sure the split in the D30 is between 3.55 and 3.73.

I thought it was 3.73 to 4.10, except in the case of the Rubi's.

Regardless.. if Hansel is going to at least 4.88s, he needs a new one.

I believe 4.88 is the lowest gear you can go on a D30. Someone correct me if I'm wrong.....

i think their is a company out there that make a 5.13 for the d30 but it might be exclusive to the reverse spiral d30
