Like I said though, I wonder how it would work if you just installed them on the rear. Lots of guys upgrade the rear-ends anyway, slap a pair on the back and puck the front just to make it level. That will 1) save the strain on the transfer case 2) save your Power steering 3) save your steering box 4) cost half as much and 5) if one track fails on the rear, you can easily carry two spare tires to throw on rather than four. All the while your primary drive wheels get the benefit of added push traction.
