Detroit locker for the street?
#1
First of all, I have a 73 Mach-1 that is a daily driver (freeway and suburbs, rain or shine). Though this is a work in progress, my plan for it is 400-450 hp, 5-speed, suspension upgrades, 3.50:1 gears...
A friend of a friend is selling his newly installed Detroit locker for a good price. I have a TrueTrac in my '68 but I've never driven a car with a locker. How are they in the street?

Firstly they work fine and are tuff. As a young bloke I loved how you could feel it engage disengage click and make other noises and generally feel very mechanical. if the detroits cheap you could give it a go and if you don't like it flip it for some cash toward the True Trac. True tracks really are the way to go as you would be aware yourself. Just my few cents worth.

Well, the price is right. Is there anything I should be aware if with a locker in the street?

they dog in and out and can be noisy if you can live with that then no not really. I like them better then regular lsds as there are no clutches to frag, there is a bit of an art with stick shifted cars and detroits when driving them through the twisties heel toeing it a bit to keep them engaged but that's sort of boy racer stuff. if the price is right then by all means give it a go

What he said I have one in my car. If you can deal with the clicking noise they work great. Mine came with a rebuilt 9" center section I got on ebay at a great price.

I had one and hated it. Perhaps mine had an issue but if I got back into the throttle coming deep out of a curve the damn thing would lock and push me off the top of curve if I kept it under power. I did dig all the noise though.

They are something you definitely have to get used to when driving. I had a set in my bronco II with 35" super swampers and it was a handful getting on and off the ramps on the highway. If you let out of the throttle around the corner then roll back into it, it would lock again and push that little bronco all over the place. But you get used to it. As far as performance they are great and are damn near indestructible. I got lucky and picked up a 9" chunk with a set of 4.11's and a Detroit soft locker for my 9 inch for $450. Which I though was a great deal then.

Got 'em in my Jeep CJ-7 with 33" TSX Swampers, and as turtle5353 mentioned, it can become a little unnerving and quite a handful when turning and getting back on the gas. I had my transmission grenade on me while rolling down the highway at 70mph - which [initially] sounded and felt A LOT like the weirdness of a Detroit Locker.

Mine didn't just click and pop... it was more like clunk and POW (just like my transmission ripping itself in half - literally)! Scared the livin sh!t out of me the first time it happened - I stopped and crawled under to make sure nothing had blown up. Sometimes, the inside wheels of the turn will 'scootch' around the corner before the click & pop (or clunk & POW depending on speed).

When I accelerate [straight line] in the Jeep, the rear end seems to squat down toward the passenger side... and when I clutch-in/let off the gas, it returns to the middle, and goes through the same motions when back on the gas (hard to explain). I believe it has something to do with lateral torsion movement that simply isn't noticed with an open differential.

But that's "normal" with a locker on the street. None of that happens on a surface that has any slippage (like dirt, mud, snow, ice, etc...)

I put one in my old 05 and the clicking noise gets annoying. I'm sending my third member out this weekend. Putting in a Currie limited slip plus for my 73 vert. Not sure how limited slip holds up to 400hp. In my 05 I had 430rwhp with the stock limited slip for 9 month before doing the Detroit and it seem to hold up ok. Not sure what the clutch plates looked like though.
