what are the advantages of having Limited Slip disc, on a 4x2 f-150 model?

i noticed all the 03 supercrew had limited slip as default on the vehicle for some reason why not the supercrew 04's? 4X2 i am speaking of.

 

Traction......in most cases
When your off road, having limeted slip on 4x2 is best. Icy conditions.... its debateable.

 

The standard or "open" differential will apply power to both wheels on level dry pavement, no problem. However, as a byproduct of a differential's ability to let one wheel rotate faster around curves than the other (an absolutely necessary feature), with one wheel on ice or slick snow, an open differential will transfer power to the wheel most easily able to turn. You have probably seen a stuck vehicle with only one wheel spinning.

With a limited slip differential, the rapid spinning of one wheel in relation to the other causes a clutch pack to engage and uses "friction" to transfer power from the free spinning wheel to the other wheel. It will not transfer full power to the other wheel, but a substantial amount. So, if one wheel is on ice and the other on dry pavement, for instance, the ice wheel will continue to spin, engaging the clutch pack, causing some power to be transferred to the other wheel allowing you to move forward.

Bottom line, even with two wheel drive, or maybe especially with two wheel drive, you are much less likely to get stuck in ice or snow, or spin one wheel while trying to pull your boat up a slick ramp, etc.

If you do any towing or go off road at all or live where it often snows, get the limited slip. If you don't tow and drive nearly all the time on good roads in a moderate climate, you probably don't need it.

 

what about mudd, i live in mesquite texas and sometimes go out to country near dirt roads and all, how would the limited slip handle in a little bit of mudd, or how much mudd will it handle or be ok in, compared to a 4X4?

 

It's not going to be like a 4X4, but LSD will help in any kind of limited traction conditions, provided one wheel has more traction than the other.

 

Limited slip will cause you to lose traction on the rear on a slippery surface when one
wheel loses traction. It's a liability, not an asset on icy roads. I'm talking 2wd here.

 

A limited slip is a posi traction when both wheels spins however the open differential is only one wheel spinning.
On my 2004 f-150 it has a limited slip and both wheels spin and on my 2000 ford ranger i have a open differential where only one wheel spins and only one wheel because the right wheel only spins. So the limites slip is what you want

 

Rent and watch "My Cousin Vinny." Marissa Tomei does a better job of explaining limited-slip than anyone before or since!

 

she was just a "yout" when she did that movie!

 

i explained it very well or at least i thought

 

Yes, but I'm sure you don't look as good!

If you're on ice, Limited slip is definitely better, provided you know what you're doing. On a heavily crowned road, on ice, if you hit the gas, the back end of the truck will slide down the hill. It sure got my attention when I first went from open to LS. The key is KNOWING HOW TO DRIVE!!! Don't rely on the vehicle to get you thru, rely on that thing between your ears.

 

Limited slip: You are MUCH more likely to spin out entirely in the snow and ice (everyone SAYS that they'll ease off the gas but no one does in an emergency hence the invention of ABS). That non spinning tire acts pretty much like a brake/drag to stop you from doing a doughnut. Lot of snow where you live? Get 4X4 open differential. That being said, if I had two wheel drive I would probably get it.

If you're talking off road the OEM LS is not that good-it won't mean the difference between getting stuck or not -particularly if you have 4 wheel drive so get a locker then.

 

My new F150 is the first rig I've had with limited slip. The first two weeks I had it, we had an ice storm that wouldn't quit. With the limited slip I almost didn't even need the 4WD on. The traction is great being that the power is going to both wheels. I don't understand how the limited slip wouldn't be the way to go, even on ice.

 

It's all in the driver.

 

first off limted slip is far icy road condt. now you will have over steer but it's not nothing you can't learn to handle, first cover of bad weather go to your local shopping mall lot (empty) and do some power slides and dare i say doughnuts to get use to the feel. an open rearend will not steer against you but at the same time you will only have one wheel doing the work for the whole truck, if you are a steet driver in bad weather areas or sand for that matter ls is a good choice if you are a offroad nut lots of rock crawling etc. save your money and put in a locker which cannot be installed if you have ls. but at the sametime a locked rear end will cause you problems on ice both wheels will spin at the sametime pushing you straight this is the setup most are refering to when talking about bad ice driving. a limted slip does just what it says one wheel can overrotate the other, there againg the slip action varies between companys so do the research and choose the one that you feel will be the best compromise none are perfect except mabey an air locker or cable locker, but even than you have to deal w/ broke air lines, stuck cables etc. now as far as the factory ls goes it is a middle of the road unit and driving on ice is one of the reasons they make it a little (weaker) slip wise but if you plan on serious mudding or crawling bring a winch is all i can say.
