Worked off and on over the weekend and finished it up yesterday afternoon.Not having any trails nearby I was only able to take it for a short test drive. I found it to make at least a 60-70% improvement in 2wd,and 4wd. I did try it in 4wd with lockers and did notice a slight improvement,maybe as much as 20% but as I mentioned it was a short drive. This was on asphault.At a stand still on concrete and ashault you can easily turn the wheel completely in each direction with one hand.Bruhaw is stoping by this afternoon and will get his opinion on how it feels.Needless to say i am very happy.
