has anyone put detroit or any other lockers in their 04-06 yet i searched a little but i saw very little locker talk i have a 2wd and don't intend to do anything major but i would like a little help keeping up with my friends is this an option?

 

Hello whiteaggieford,

Detroit Locker currently makes a unit for both the Ford 8.8 and 9.75 rear axle. I think many people opt for limited slip's rather than lockers on F-150's because their street-ability and towing performance is not good, but it certainly can be done.

 

well are the lockers that lock on their own and free up on their own usually bad on the street?

 

I recently did a lot research into this. What I got told by the guys at Randys is that the auto type lockers that disengage and engage on their own do work on the street but it will be noticeable when turning. One of the guys on here told me that you will feel a jerk when turning but will get use to it not even notice it after a while , so I guess its not that bad but still noticeable. I dont know if you have looked into the detroit tru-trac, but what I have been told is that the tru-trac is WAY better than the the stock limited slip that comes with the truck. Thats what I have decided to go with front and back.

 

Would the tru trac be the same as an air locker? Just curious..

From what I understood the tru-trac will send power to both wheels when enough torque is applied and to the other when one loses traction. If you want power to be applied to both wheels at all times then a locker would be the only way to go. Again, this is only from talking to the guys at Randy's. I wont be getting mine till after I get home so maybe someone who already has them installed can answer better.

 

The Detroit true-trac is a limited slip, I have one on my truck it is very smooth on the street and engages very well off road, it's a good option so is the Auburn LS I had one of those on another truck. The Ford OEM limited slip is much less aggressive as far as engaging when the one tire spins and is not very good. You can get, at least for the 8.8 rear axle, a selectable locker, Eaton and ABR makes them but not nothing for the 9.75. A selectable locker lets you turn it off on the street and on off-road, but they are much more expensive.

 

Detroit True-Trac is the way to go.
