We installed the Detroit after the second Lock-right blow-up. The Explorer was always used as a daily driver, and trail vehicle. My X had to drive 45 miles (one way), to work.
Even though the Detroit is a hard locker, it does have springs and things to allow it to release when a vehicle goes around a corner. The only way it will stay locked around the corner is if you are hard on the gas. There is an audible clicking around corners, but it is significantly more quiet than the Lock-rights were.
Part of the reason for the nice behavior is the longer wheelbase, and weight of the Explorer. However, Detroit has also made changes. The springs that release it in corners are now much softer, so all transitions are much softer. I have noticed no unusual tire wear on the rear, nor have I noticed odd handling characteristics. With the shocks all turned up to 5, I have still been able to play canyon carver with my 5500lb beast.
I in no way find the Detroit objectionable on the road. Like I said, Rick drove the truck, and due to the invisible nature of the Detroit, didn't even remember I had one.
Of course, this is just my opinion...... I may be wrong. Dead Link Removed)
Good luck on your choice.
