i was wondering if anyone knows how i can get or which gears to look for for my sj410.  I am hoping that lowering the gears will add some bottom end power for me too...Any ideas?

512 from stock tracker or 586?? from calamini

I THINK THAT THIS REFERS FOR THE SIDE KICK TRACK  NOT WHAT HE WAS LOOKING FOR  :-/

I think i am more looking for what i will need for gears and how hard are they to find...Do you think that i will acheive what i am looking for? (more power out of small engine<1000cc>)  If not, what will?

SJ diffs don't fit the 410 axles you would need to source some LJ80 diffs, these drop straight in with the third member and reduce the overall gearing a fair bit. I forget how much exactly, I'll try and remember to look it up later.

Edit:
The FSM gives the stock 410 diff ratio as 4.111:1
The LJ80 is quoted on the web as 4.556:1

does anyone know if sammyy parts interchange with sj410, since sammy replaced that?  i am refering mosly to the drivelines in question..i have three differnt parts trucks but dont want to start mixing if it may not work.

thanks for your insight and info, it is helping this newbie a lot...lol
