best performance 9" limited slip/ locker

[scottymonte]

Hello I am looking for feed back to help decide which dif to purchase. Vehicle use will be mixed street, drag, autox, general spirited driving. Monte has moser 9" with 31 spline axles with manual trans.

I use a Detroit True Trac. No problems and I enjoy the engagement when the power is applied. I have used mine for street, autocross and drag. 3000lbs car and +-450hp.

I think tru-track is what I am leaning to. Although I have heard good and bad things about it. Seams like mostly good.

Have a look at the Wave track, they are stronger.

Wave track looks great, just a little pricey. Looks like $1000.00 is going rate.

I will be ordering my detroit locker in the next week or so.

Tru trac is great and is what is in my car. It's light and we are only dealing with 425 ponies. It seems when you get near the 600 horse number the wavetrac is the answer. The trutrac doesn't seem to like WFO coming out of a turn.

Bryce, I had read in another thread you were going with a locker....why? If you are going straight it is the answer for sure, but i would think the locking/unlocking would upset the car going left and right.

Yep, you read that correctly. It will drive differently but I think it will be the best solution for my car. As you turn in under throttle it will make the car push, but normally that would be when you are hard on the brakes.

Bryce, can you explain how it works powering out of a corner as you are decreasing steering angle?

A locker will be a big mistake IMO if you will be attending Auto-X events. I have owned MANY cars with Lockers and are great for straight lines.....but will be a handfull at the Auto-X course.

There are a few big names running lockers and mini spools.

I ran a Locker in II Much. It worked fine on the autoX and at Road Atlanta. The only time I noticed its harshness was turning while in reverse.

I have seen a lot of cars go around the cones at SCCA events and goodguys and I have talked with builders and drivers. I also talked with Eaton at the SEMA show and discussed my options. I do not want a limited slip. I dont want the inside tire to be spinning.

[Bryce]

Moser is running a special on the wavetrac and axles. I am considering this right now!

Hey Bryce, not sure if this was a type error or not and did not want this info to mislead others....but as you "turn in under throttle", (with a D-Locker) both wheels will stay locked and spin. If you happen to be off the throttle, the outside wheel will ratchet free.

Much better choice IMO! I know its more expensive....but does have advantages. I do like D-lockers as well, but believe would be much better for straight lines or a more open road course....they just dont like quick transitions from left to right going from accel to decell like Auto-X will do

Sorry I meant, I do not want the inside tire slipping without driving the outside.

I did not like the fact that the WaveTrac never locks up, it will always bias the torque. The detroit locker is predictable, it always does the same thing. I can drive with confidence knowing what the car will do with my inputs.

Under throttle a detroit locker will drive the inside wheel, whiel letting the outside wheel ratchet, until the insde wheel is spinning as fast as the outside wheel. This will be a hard impulse load but if you know its going to happen you can be prepared. The older Detroit lockers could have up to a 1/4 turn on the driveshaft until it would lock up, the new ones are better.

The only big issue is in reverse it will drive the outside wheel.

Interesting.....

the best would be the I think it's called the grizzly

[TheJDMan]

I'm a little confused, is the Detroit True Trac different than the Detroit Locker? Does anyone have an opinion on the Ford Trac Loc 4 pinion posi unit?

[scottymonte]

I have decided to go with a detroit locker, friend of mine is selling me a complete third member with the detroit locker for a good price.
Could not pass it up.
If I find I do not like the way it feels, I will bite the bullet and get a wave track.
