Limited slip or Locker for street

I plan to eventually install, in my 07' Ram 1500 Quad Cab, either an Auburn Limited Slip, or a Detroit Locker, and Motion 4.56 gears. For those members who run either one, which would be best for an everyday street truck? I have read that a locker will increase the tire wear, on the street, compared to the limited slip type that uses clutches.

The DTT is the way to go. For a street truck it will almost never wear out and have no issues. I have driven mine on the street since 2008/9 and race day it very hard and it’s only now showing possible issues and that I’m not sure is even the issue may just be my suspension.

Keith, when using 4:56 gear with the DTT did you have to grind any teeth to install the center pin? Auburn I'm pretty sure you do..

I did not have to oddly enough. The DTT just has a big slug no pin bit Ariel’s we did have to grind two edges to get it to fit believe the gear set makes the difference.

I'm surprised, I thought the DTT had clearance for the ring. Regardless, I would still choose the DTT. Mine takes a beating and still run flawlessly.

What does DTT mean? Is it the Detroit Truetrac differential.

Yes the helical cut gear style not clutches to wear out ever.

for the once and done type build, the DDT is worth the money, Not sure what size tire your running, some of the bigger tires have a bit of a clunk noise with some real tight turns.
I myself prefer the Trac Loc, but you won't get the long term mileage out of them that you will with a DDT.

DTT, Motive 4:56's, Sonnax for the tranny and maybe a deeper aftermarket tranny pan if you desire...this is the ONLY way to go for a street truck IMO.

You get more street fun, increased fuel mileage (getting the engine into it's prime RPM range) and it makes the tranny work less (and we all know the crappy 545 RFE needs all the assistance it can get).


My 2 Cents,

As someone who has a locker in my R/T, I love it. It's raw, a bit harsh, and just feels so cool when it grabs. Yup the tires chatter turning, if locked, but that's easy enough to cure. Let off the gas. If you like the twisties, as opposed to drags, I wouldn't suggest one unless you really know how to drive. It could get you in trouble quick. I have a Powertrax and I would not suggest one. All that being said, next time it will be the real Detroit Locker version. You get what you pay for.
