Calmini

All I can say is...LSD GOOD...LSD VERY VERY GOOD...

However, with respect to you question about differentials, the only company I know that sells one is Calmini.  I know those Rocky Road guys sell a locking diff...but I would certainly prefer the limited slip.  Not advice, just opinion.

hahaha...hahaha ok im done being dumb now =)..still funny though lol

I don't think that those are 30's, maybey 225's, I placed a 235 next to my stock Tracker once and it just didn't look like it was going to fit without a lift.  I know that the older ones do, but hte 99's and up might be tight..............Then again..........I could be wrong.

Placing a tire next to a vehicle is not a good way of checking to see if it will fit. You would have to raise the vehicle up so the center of the hub lines up with the center of the tire/wheel your thinking of using. The hight you raise the vehicle is the approximate hight you would gain with the new tires mounted.

The pre "99 trucks were not consistent, a 30" tire might clear on one vehicle but rub on a next. Some trucks  could only clear a 225-75-R15 with out rubbing off road.

Mount the tire you got and see what happens. Thats the ONLY way you'll know not by looking at a pic!

It bothers me when people doubt other people with out even trying. Thats like when we said we were going to put headers on a "00 four banger Tracker. This know it all on car domain swore up and down calling us every name in the book that there was no such thing available.

JUST BECAUSE EVERY ONE ELSE IS NOT DOING IT DOES NOT MEAN IT CAN'T BE DONE OR IT'S WRONG..

MMMMmmmmm Suzisport headers   I want them too. Just give me some time, the'll be mine!

MMMMMMMMMM.......Header on a 2.0 16V..........
