Is the sensor just a replacement part? Kinda like replacing the head fasteners when you rebuild the motor?

I went with a KAAZ Super Q LSD in my custom Lentech Auto. The Lentech shipped last Friday so I should have it and installed this weekend. I never heard anyone on FF using the KAAZ. I will let everyone know how it is. Also, I know that there are different types of LSD. Like the Quaife is an ATB Helical type, the KAAZ is a 1.5 way Clutch Type and the Torsen is a T2 Torque Sensing Torque Biasing. I am not sure what all the difference is, I think they operate different. I did look up how the KAAZ works, I would be typing forever to explain. But if anyone knows and wants to explain the differences I would be all ears.

Peace
Joe

i know the clutch type is a lot better suited for track/drag and isnt really ideal for a street driven car... I think it has something to do with engine harmonics and harshness.. Personally all i really care about is using as much of my power as i can under any circumstance. I ran my car in autocross and all my power was on the inner wheel and it would just spin... drag starts as well where my tires break loose. 1 way is accel only(best for fwd) means as soon as you lift the diff acts as an open diff allowing for better turn-in, 2 way is accel and decel(very bad for fwd)and will push the car through the corner(understeer) and 1.5 has a reduced decel and is more for track cars as the decel isnt 100% open like 1 way.(can help stability though not sure about on a fwd car).

The torque sensing is exactly as it sounds.. takes the torque sensed on the driveshafts and distributes bias accordingly. the ATB is essentially the same. Automatic Torque Biasing. Correct me if im wrong though... "That means it’s much smoother in operation, because unlike a conventional plate-style LSD, it never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree and never locks." <--Quaife's website.

I read allot about this and everyone has their own opinion some prefer the clutch type and some the other types. And each has its ups and downs.

So... to each his own

The new KAAZ does have WPC treatment which is supposed to make it smoother and require no break in.


I just got the call - my lentech is here. Going in this Saturday. Woo Hoo

Peace.

The speed senser fits inside one of the carrier bearings. Your going to install new bearings anyway. So to save time pulling the bearing off of the old diff. to get to a 7.00 speed senser, I just added a speed senser to the order w/ the bearings.

Yes you can replace the clutchs & change the torque bias vs a torsen where you can't change the torque bias. I went w/ the torsen, cause it works great w/ 5.0L mustangs, vs the trac-loks.

We've been using KAAZ diff's in both team rally cars and they've been awesome. One is on it's 3rd 1/2 season and the other on it's second. No issues with either. Had them set to 60% lock to preserve turn in. They have not needed a rebuild yet but the one that has been in longer use is starting to get there.

For what your doing the Kaaz diff's work great & you can adjust bais, where a atb diff. wouldn't work if you get one wheel off the ground.

Hey Juggernaut, I have a KAAZ in my Lentech automatic. Just got it for about a month now. It is the Super Q version. At first it was clunky and noisy but after about 2000 miles it is now quiet and rarely makes any noise.

Do you have the new Super Q or the older ones?

If you have the Super Q did you have a similar experience with noise in the beginning of running it?

If you have one of the older ones, are they noisy?

Thanks,
Joe
