(Suretrac is a limited slip)
I like the idea of the Ox. It's effective and it's simple.
Having lockers like the EZ Locker on the street can cause problems. I put one in the back of that 1/2 ton I mentioned. There was an open diff up front. If the road was snow covered and I was going uphill, the rear end would try to come around. If I were going downhill in gear, the rear tires would slide and if the road was cambered. . the truck would slide in that direction.
Open diffs make a very streetable truck. (one your girlfriend can
drive)
The Suretrac may have a smooth engagement, but I dont' think
it will be the best for snow and ice. Especially if you want to run
them front and rear. Then things really get fun in the snow.
I have an International Travelall with limited slip front and rear and an NP205 transfer case. (meaning it's true 4 wheel drive)
It's fun off road, but I wouldn't want to drive it back and forth to work!
