Ring and Pinion Sets for the 8.25

Will either of these work for regearing to 4.10? Does brand matter too much? Spline count shouldn't matter since I'm changing everything, right?

I'd get the rears from rockyroad.

Remember that only the rears they sell will work. You still have to get the fronts from the link you posted.

Why will their gears be the only ones that work??? The only reason I ask is because I just bought the rears from Rusty... :shock:

Edit: I re-read your post and now I understand. Yes I bought the rears from Rusty and the fronts are Mopar.

you should be set then. I'm sure Rusty's are just as good as the US Ring & Pinion that Rocky Road sells.

Sorry about confusing you. I didn;t mean that only Rocky Road will work, I meant that the front gears Rocky Road sells won't.

I recently called RR and they said that they would work up front. What is the reason why they will not?

They are designed for the Dana 30. We have a Dana 30a.

This is what Al had said about them..

"The Dana 30A pinion gear in the front have longer shafts than the reg. Dana 30. This is what I was told a while back by a guy at Dana. I belive no after market company has gear sets yet. I have swapped in the 4.10, they work fine, but I need 4.56's with the 33's.

Skyjump, that first link (from ebay) is for 27 spline. Your 8.25 is 29 spline. Do you want a weaker rearend?

I haven't really found any 4.10 gears for the 8.25 in a 29 spline...guess I'll install whatever Rusty's sends me. Lemme know if I made a mistake here...have you seen any aftermarket 4.10 gears with 29 spline???

So just because Al said that then it must be true... :roll:

Does it say anywhere whether that is 27 or 29 spline though? I even looked on the manufacturer's site and it didn't specify. And how does 4.11 work with the 4.10 front or is that just a typo or is the difference to small to matter?

I'm pretty sure they are 29 spline. You can put 4.11's or 4.09's with 4.10's with no problems. They're so close that they are generally considered to be the same thing.
