mattracks 101...... they use a serious gear reduction to get the power to the ground. so unless you plan to regear the front, going "half tracked" would only damage the drivetrain. there are alot of moving parts, but in it's defense they are strong as hell and last a long time. debris generally isn't a issue either. as I said, I have them on my sportsman 700. water, mud, brush, sand, rocks, etc... nothing hurts them. they ride unusually well, speed wasn't affected much, and power is there. nowhere near like riding on flat tires.
I inquired about them for my dodge, the price is too high for my blood. also, the steering has to be upgraded. they suggest hydrolic steering.... specifically a brand called rock ram. also said turning the wheel while standing still would either damage the tracks, or the steering... you must be moving. they are also street legal. but speeds over 45 isn't recommended. they are very heavy, about 200lbs each. (depending on application). I hope this answered some questions. as I said, I have them now on my atv and was wanting them on my dodge. oh, one last thing. depending on the vehicle, a lift is sometimes required. on a cherokee, for it to work properly you'd need roughly a 2" lift.
if my girlfriend was as dirty as my jeep, we'd be married already!
