**** just get a Powertrax. They act like a full diff under normal driving but any torque increase and they lock up and stay locked. Best part is you can install them yourself in about an hour in an open diff. They run about 375 and are rated for over 1000 HP...Zed

Oh yeah and no cones or clutches to wear out either. And not as noisey as detroit lockers.

 

rated for over 1000hp....

 

I got my from Randys ring and pinion. www.diferentials.com. It cost me about $350. I suggest you get the carrier bearings to. It makes the install quicker. All I had to do was take mine out and put the knew one in with the same shims. But make sure you have some extras just in case and get a mike gauge to check the play before you button it up.

 

Go to powertrax.com. These units were developed for baja racing if I remember correctly so they can take a beating. Actully I remember reading that they said you'd break the axles before you would break the units...Zed

 

Lockers do not have the street manners that Limited-Slip differentials have.

Detroits are locked all the time and will then ratchet when needed under low torque. Posis are nearly open all the time and tighten up based on load.

The Eaton Posi is silent, it's predicatable, and it really is pefect for a high-horsepower street-driven vehicle. It's terrible off-road though, especially in mud or rough terrian. If one wheel becomes unloaded enough there will not be enough torque to lock-up the mechanism.

A Detroit Locker has been the best off-road choice for decades. It will handle mud, sand and rock crawling even with one wheel completely in the air. On the street though they can be annoying and driving in the winter on ice would be suicide. Detroit would be a good choice for a race-only vehicle too.

 

I'm With JamesB. The powertrax is a locker to. Friendly in the woods but unpredictable on the street. They may handle 1000hp but a few hundred foot pounds of torque will break them. Seen to many people go through them offroading. Lockers in the woods. Posi on the street.

 

most baja trucks only run spools. they have no reason to allow different tire speeds between the two.

 

So no one here would use a powertrax for the street?

What makes it so easy to install in one hour? I thought all differentials took hours and hours to install?

Also... are you guys saying that with a powertrax that under normal driving conditions it would sound like some giant ratchet spinning?

Thanks,
Derek

 

won't you chirp the rear tires with the Detroit locker around corners??

I have my truck setup for handling and dragging..... I really am trying to look into a full locker cuz I dont want to deal with wearing clutches.

I like the idea of the Eaton E-locker, but this obviously has some moving parts in it as well... it's pretty pricey also.

what do you guys think?

 

With my detroit i sometimes hear it click, but not often. After 2 years of abuse it still is like the day i bought it. And it acts like an open diff. around town, even in the snow. It only locks when one wheel spins. Usless one wheel spins it stays unlocked.

Only prob with it is every now and then after the 225 shot it will stick locked. All i have to do then is put it in reverse then back into drive and its good.
