I will agree with 50% of the Detroit info posted above. It has killer traction off road and is a very solid, strong differential that will last darn near forever.
As far as Daily Driving with it, I find that it is noisey/clanky/jerky and sometimes down right scary to drive on the street with it. It can have torque steer occasionally too. This is all from a Detroit "Soft Locker" application in my Jeep TJ. Which was designed to "Soften" some of the harshness of the Detroit locker. The "soft locker" is not available for the Chrysler 9.25, so you get the old style "rugged" one.
Your wife will definetly not like driving it at all IMO.
If you off road quite a bit, the Detroit is awesome and has it's trade off's that make having one worth while. If your truck is a mostly DD and only off roads occassionally, I would not recommend one.
If you absolutely have to have a "Locker", the Powertrax No-Slip or Lock-Rite are an economical solution for the occasional off roader. These "lunchbox" lockers add strength over your stock open diff and have 100% lockup traction like the Detroit Locker does without the slop and loud noises traditionally associated with a Detroit (lunchbox lockers do make a "clicking sound" around corners, but not the clanky noises you get with the Detroit.).
Lunchbox lockers are not anywhere near as strong as a full Detroit, but are typically much cheaper. Labor to install them is way less too as you do not have to set up the differential again, not even backlash, as you are reusing the stock carrier.
All that said, if you want smooth traction for your DD, get a LSD like the Trutrac or Auburn unit and live with it's limitations off road.
A traction step-up from the LSD is to add a "lunchbox locker" to your open carrier, and a full out strength and traction improvement would be a Detroit. All of these options have their own characteristics and limitations................................................................................that is until somebody comes out with a selectable locker for the 9.25 rear and then all bets are off!
