Trac-loc

How does one find out about the trac-loc. I have a stock 44 with 3.73, 05 Sport. Is it something factory? I keep hearing about it.

Trac-Lock is a fancy name for limited slip. Do a burn out, and if you got 2 lines, you have one.

ahhhh, I see. But wouldn't limited slip leave 1 mark? (one wheel wonder?) I always thought posi left two.

A limited slip working right will burn posi. So doing a burnout won't tell you for sure, since the clutches/springs/whatever could be worn out.

"Posi-traction" is just another name like Trac-Loc is.
Do it in the dirt, you'll get better results.

Other factory names for LSDs include
* Chevrolet: Positraction
* Pontiac: Safe-T-Track
* Ford: Equa-Lock and Trac-Lok
* American Motors Corporation: Twin-Grip
* Mopar: Sure Grip
* Ferrari: E-Diff
* Fiat: Viscodrive
* TVR: Hydratrak
* Oldsmobile: Anti-Spin
* Jeep: Trac-Lok (clutch-type mechanical) and Tru-Lok (gear-type mechanical)

With my miata i tested it another way... one tire goes in the dirt, the other one on the pavement. Try to do a small burnout. If your jeep takes off fast, you have an lsd. If your jeep just stays there and burns out the tire on the dirt. You have a very weak and worn out lsd or nothing at all.

On my Durango, the option was called "anti-spin"

I just put The Dana 35c Trac-loc in my TJ pulled the open carrier and dropped right in.
I did not want something too agressive becouse i can't afford new axles so this was an option for alittle help on light trail wheeling for me.

Hopefully soon i will put an aussie up front and then be done for a while.

Oh here is another way to test lsd... lift one rear tire up. Put the tranny or the tcase in NEUTRAL (not park or in gear) The driveshaft has to be free to spin from the engine.

Try to turn the lifted up tire. If you can turn it and the driveshaft turns, you have an open one. If the lifted tire will not turn nor the driveshaft wont turn either, you have LSD.

If you have LSD you will pop a blood vessel before the lifted tire spins.

This is the safest way i can think of testing it.
