with anything other then bolt ons, its garbage, its not a preformance part, it is a factory part off the ranger/bronco 2s originally, if you want a PREFORMANCE LSD go with a detroit true trac

 

I wouldn't say its garbage either.. Considering Scrming put about 500 ft/lb of tq on his T-lok and his engine gave up before it did.
Also, there a quite a few members here who are F/I and run a T-lok with no failures.

 

exactly, i was goin to bring up scrmings car as well.
Yes i have the truetrac in my car, but i have huge plans, tlok is plenty good for what most ppl are going to throw at it, f/i or not.

 

i live in upstate ny and we had a steeeeeeeeeeeeep *** driveway, and at that time i was driving an 86 gt that got about 330 to the wheels with a eaton posi-traction. with decent tread on all-seasons i was able to claw up all the way in an inch of snow, it doesnt sound like much but its like ice when its cold. I cant tell you about the t-lok, or the true trak, just that besides the maintnance required on the posi-trak, I like the posi track, and it might be a good trade off being more $ than a t-lok, and less than a true-track. All i had to do in the summer was turn in sharp and and blip the gas to get the car sideways, good for having fun, might not be what youre looking for.

 

Traction lok is worse for the snow, unless youre stuck. With traction lok, because both of the wheels get power, when one wheel loses traction so does the other. So basically, if youre going around a turn and the RR tire loses traction the LR tire will also lose traction and this will cause you to spin out. An open differential, only put power to one wheel, so if the RR tire loses traction the LR will not therefore giving you more stability. I live in MI and we get lots of snow here, I drove my stang through several of em, all I gotta say is with T-Lok you gotta be extra careful. As fo the gear, in the snow forget it. Bad idea. Youll lose traction even easier.
-P.

 

well ive never had problems with it but now it got me wondering. If it breaks whats happens it goes back to one wheel or it has to be towed to get it fixed? if it just goes to one wheel im going to keep it if it has to be towed....

 

t-lok will be better in the snow... you will have twice the surface area that has power. you will have less of a chance of getting stuck and if you do spin both tires will spin evenly and you will have less of a chance of your car turning sideways and flying off of the road. I dont know what these other guys are thinkin.

 

Wow, what a variety of opinions......

Ok, an open differential will divert all available engine power to the wheel with the least traction - it tends to bias toward the right side, due to the direction of rotation of the pinion. This is why we get 'one wheel' burnouts. This is really bad if you have that one wheel on something slippery (mud, ice, packed snow, whatever). Basically, once you stop, you can't get going again.

If you are moving, it is harder to 'spin it out', because you have 3 wheels idling along, supporting the weight of the car.

A T-Lock (positraction, whatever - different manufacturers have different names for similar technology) is a friction device which causes both drive wheels to TEND to rotate at the same speed. I say tend because the device is designed to slip somewhat, to allow the wheels to rotate at different speeds - when going around a corner, for example. It is possible to overcome the system in certain situations. I once got my 03 F150 high centered on a snowbank - 3 wheels in the air, left rear solidly on the ground. The 'up' wheels would spin, but the 'down' one wouldn't get enough drive to move the truck (lot of digging went into that day). If I had a locking differential on it, a Detroit Locker or a Spicer, etc - that one wheel would have likely been enough to drag me off.

A limited slip will not cause you to lose traction unless you are one of those unfortunate souls whose accelerator pedal only has 2 positions....

If you are stopped on a slippery surface, you will have both drive wheels pulling more or less equally when you attempt to move. Look at it this way - are you more likely to get 4000 pounds moving pushing it with one wheel, or two?

As far as spin outs go, if you nail the gas in a corner and cause half of the wheels supporting the weight of the car to lose traction, sure you are going to spin - hell, if you did the same thing on a motorcycle, you would get the same result......and for the same reason.

As for the gears, lower gears (higher numerically) should give you better control on slippery surfaces. The lower gears allow the car to move more slowly at idle speed, as well as letting the engine run at higher rpm (closer to the powerband) at lower speeds.

If you have ever spent any time off road, you will know that the lower your gears and the more wheels you have driving, the better

all good but that didnt answer my question :P

 

petepete - if a (Ford Racing) tlok breaks, it goes back to one-wheel-drive. Other differentials may behave differently.
