Well I just realized that my truck does not have a Limited slip rear end(I did a brake stand, one wheel peal). What are my options to get those boys rollin together. Limited slip or Posi, which one will get the power down better.

They are the same thing. Limited slip is the only thing that is available in your rear unless you want a locker, which is always locked and chirps when turning. You will have to lock your front if you have 4x4 otherwise it will be 3x4 lol. Good luck it wont be cheap.

 

I have a 4x2. Wheres a good place to find a limited slip. And how can I find out what rear end I have.

Thanks

A limited slip rear end will always have power to only one wheel/tire at a time. It's possible to have power to all wheels but not at the same time, depends on traction. example...one rear tire comes off the ground the power is supposed to transfer to the other rear tire still on the ground with a limited slip rear end. Usually you will see the tire in the air spin while the one on the ground is motionless. That's the SLIP part.

To have a real 4 x 4 you would have to install lockers in the front and rear, then you would have 2 wheel rear drive under power and 4 wheel drive (when selected) under power.

Detroits will not chirp around corners if you let off the gas, power/throttle thru a turn and yes....one side chirps due to the shorter turn.

So all these 4x4's out there are actually 4x2's unless modded.

 

Hmmm, I had a 3.73 Limited slip in my 99 F-150 and both wheels turned all the time, whether I was driving in the snow in the rain or doing some burnouts both of them always spun at the same time.
Where can I find a Limited slip dif for my truck?

I dont know what your talking about HK308. I have LS and all 4 spin when in snow, and when I burnout there are two big black streaks. What would be the point of LS if only one wheel spun lol.

 

Thats wrong.............. What your describing is a regular differential.

Limited slip will allow one wheel to spin faster then the other, But both wheels will be turning. If one wheel is spinning and the other is completely motionless, then its not a limited slip.

 

2 Questions

1. How can I find out what rear-end I have?

2. Can someone please tell me were I can find a LTD Slip diff. that will fit?

I found one @ Jegs.com, its from FRPP, its Ford Racing Differentials Traction-Lok (clutch type heavy duty diff)

Thanks again

well I have to agree with you on all tires having power and spinning in the snow with LS, I have done that. But, all the LS diffs that I have used only spun the tire that was in the air, the tire with no traction. I should have said "in certain situations" you only have power to one tire with a LS diff. sry

check out 1sawtooth's post, midway down the reply thread titled "2nd review"

this is what I have seen also, that's why I installed detroit lockers on my previous trucks.

 

Then it isnt a limited slip, or maybe yours is just broken????

When a wheel starts to spin on a limited slip while the other wheel doesnt, It causes pressure on the clutch pack in the rear end to increase torque to the non moving wheel.


Your giving out bad info...

 

anyone out there who could answer my questions

PLEASE

 

Kicknblue already did,


Posi and limited slip are the same thing. So your question of which is better really has no answer.

 

I asked a couple of ?s later on, they are in the #8 post.

 

oh sorry

 

If you have the 5.4 engine, then you have a 9.75" rear. Otherwise you have an 8.8" rear. Check your local driveline shops. L.S. installed should be in the neighborhood of about $500.
