I am completly new to the offroading world and I chose to get a Tracker after reading so many rave reviews.  But I am so confused with gearing and whats best for bigger tires.  Can someone help me and break things down to a simpler explination?  I am looking to put 33" Super Swampers on it with the 6" Calmini super articulation lift.  I know there will need to be cutting and banging done for fitment but what gears go where and whats the best combination?  I would really apreciate any advise.  I am from the chicagoland area and wouldl ove to find someone to do some work with if theres anyone out there.   

Thank You,

Your choices are rather limited these days, for a 33" tire you can use
a undertaker, or find a set of 5.83 gears, I have 33 Swamper LTBs and
the 5.83 gears, as well as a 4.24:1 T-case gear set, I would of got the
undertaker, had it been available when I got the T-case gears

You could go for a Shogun or Kicker 3 setup.  That would put you right in range for the 33" tires and give you dual transfer cases.

Did I miss something or did you not mention if your Tracker is a 5 speed or Auto trans? If it is the 5 speed you are truely limited in gearing choices as stated below , but if it's an auto, ( 4.30 final drive gears)   you can swap in the gearsets from a 5 speed manual ( 5.125 final drive gearsets) which would get you pretty good gearing for 33's.
