not sure on the tracker, i know guys run them on sammis, not sure how the t-case output sits on a tracker, on a sammi you need a passenger side pumkin in the front ,wich the toyotas have, the rear is also offset a little, some guys run the centered toyota pumkin and say it works fine... seems a little odd but hey whatever,also they are around 6-7 inches wider , great for alot of wheelin but maybe not what you want on the street
and thats a really low price, im geussin they have gone up a bit, 84s are the most desirable becouse the housing truss runs all the way ender the spring perch on the long side, dont forget gears and lockers!
