I just bought a 01 s2k a couple of months ago and i'm wanting to put a 4.77 gear in it and have heard of people putting the kia gear in them. I wanted to know if anybody out there has done this and if so is it a direct fit, what all parts do I need, how do you like it, etc.. Sorry i'm new to the site and I know this has proubaly been posted before somewhere. Thanks.

 

Yeah its great. Id never go back, and it is a direct fit. Same company (mazda) make both our diff and the kia diff.

Heres the thread i posted when i had it done, everythings listed in there including part numbers

Here are two links to group buys here on the forum. There is some good info on everything you need to know

Good luck

 

I'm running them and I LOVE them. The car drives so much nicer. 6 months so far and no issues whatsoever
