How durable are the Powertrax units in a full size pickup. I have an 01 2wd reg cab 4.6 and I have been looking at possibly installing a limited slip differential. My truck has a few bolt-on parts now, and will eventually have headers, shift kit and some type of aftermarket tuning (a programmer or possibly add a database to the tuning software I already use so I can dial it in myself).
Let me know what you think.

 

A limited slip, no matter the kind is usually strong enough to handle tires up to 33"s no problem, bigger than that, you run the risk of tearing up the clutches in it.
You should be able to run 400 rwhp through it, and be fine.

 

Are you running this particular (Powertrax) unit?

I run an Auburn LSD in my Lightning and it's ok, but after 7 years of abuse, it's starting to slip. I'm sure it would work fine in my 01 being that it makes less power. I am interested in the powertrax piece because it says that it doesn't need shimming.

 

I don't have the powertrax, but I have a weaker spicer limited slip, and it works fine. First sign of slipping, and both wheels start spinning. Now of coarse, it won't be 100% to each wheel, b/c that's not how a LS works, but 60/40 new, and shouldn't be any worst than 70/30 worn.

 

I'm aware of how they work...just wanted to know if anyone here is running one of the Powertrax LSD's in an 8.8" rear end.

 

Where have you seen a Powertrax limited slip?
Just curious, I've only seen their lockers.

 

It was on Summit's website, and from what I gather, it's not a clutch type LSD.
It got my attention because it's supposed to act like an LSD (no ratcheting) and locks up just like a locker.

This is the description:
"The Powertrax No-Slip Traction Systems are the latest design in traction-adding differential technology. They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring designs reduce the backlash, and, therefore, the driveline windup. Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit."

It actually sounds llike it works much like the Detroit Tru-Trax unit.

 

Since it is not a limited-slip the locker will hold up fine for your truck, but I have a very simular aussie locker which is cheaper, and performes just as good as the power-track unit.

 

A couple of things that got my attention is that they're stonger than many of the clutch type units and about the same in price. I'd like to see someone chime in that has one to see if the install is as easy they claim (no ring and pinion set up required).

 

This is not a limited slip.
It is a locker, completly different.
The powertrax, lock right, aussie locker, and quick lock, all are drop in(lunch box) lockers.
You take out the spider gears in a open diff, and drop in the locker, and then your good to go. Right, no messing with the ring and pinion.

 

I am running a powertrax Lock Right on my truck. It pulls fairly well. Sometimes only one tire pulls, still getting use to the locker.
