My 2005 Supercrew Lariat came loaded from the factory with everything from adjustable pedals to overhead DVD but it says it only has non-limited slip rear?

Why would the dealer order a truck seemingly loaded with skid plates but non-limited slip. In the last snow storm i did not get stuck but I am worried about what I am missing out on by not having a posi rear.


Thanks
Chris

 

Most dealers dont know how to spec a truck.In there defense though it would be hard to please everyone.Thats why i order mine im paying for the options i want nothing more.

 

I've never had a problem in the winter with my truck because if it's limited slip. I've driven pickups before with an open diff, and all you do is spin, spin, spin...

 

4X4's with non LS do great in the snow.

Actually, LS diff's cause you to "kick out" a lot in the snow once both wheels break loose. Having that "trailing" wheel on a non LS helps you go straight in the snow.

Half the people here complain about LS diffs because they grab and moan in tight turns (like they're supposed to). They fill their Diff's with Friction modifier, efectively getting rid of the LS function.

Now ME, I have a LS, as it does help in the Really bad stuff.. but I wouldn't worry about it...

 

I love my limited slip. I thought the only trucks that came with skid plates was the FX4 and all the FX4s had LSs?

 

What do you guys think of a getting rid of the limited slip and adding a locker on a '06 4x4? Do you think its worth the money?

 

Do you off-road enough to justify a locker?

If the answer is no, then it's not worth it.

 

in my opinioin ford stock posi sucks anyways. you are better off going with an aftermarket one anyways. i just got eaton posi in my truck its like night and day compared to stock LS.
what do you use the truck for... if you really need it then yes but a locker can really tear up your tires on the street if you're not careful. i would just go with a good aftermarket posi.

 

Fully agree about the kicking out on the LS.

edited to add, my 08 King Ranch came with skid plates as did my 05 Lariat

 

Skid plates can come on the Lariat 4X4 as well. Ford LS is meh.

 

not having the Limited Slip can suck pretty badly in the snow/mud. I've gotten stuck in my driveway before with a non-LS F-150 :o

but the Limited Slip won't be your fix all either. as mentioned, it causes a complete loss of traction if you break the tires loose...which can be pretty scary at speed


see if you can find a junkyard axle with the same gearset and LS...then it would be a direct swap without having to mess with the internals.

most LS units run about $500+ and then the install can be a pretty penny as well.



all that being said, I love my factory LS. I'm supercharged and I leave dual black marks when I burnout...so it seems to be working
that's because you are running 15" wide tires...I'd like to see any OEM unit take that kinda abuse and hold up well...I wouldn't be surprised if your Eaton goes the same way shortly...a locker is better in your case
they are available at an extra cost...just like the limited slip option

 

The ford trac-loc LS is not the best by any means but it is better than an open diff any day. If you want a true LS diff the Detroit tru-trac is probably the best one out there. But considering that the LS option costs something like $295 from Ford and the Tru trac will cost around $1000, the Ford LS is probably the best option for the money.

 

The Tru Trac is what I am going to have installed when I get the money! Its all gears, no clutches! I would have got a factory one but its not an option for the 7-lug 10.25

 

Most dealers don't pay alot, if any attention to the drive train options like gear ratios and LS. Because most people just plain don't care.

Unless you use the truck off-road or other situations where having a locked rear is a MUST, its not worth it. After getting stuck a couple of times at work I had a Detroit Locker put in the rear and a Auburn posi up front in my 94 F150 and regeared to 4.10's. Since having them installed I have yet, key word yet, to get stuck. It is kinda fun pulling out the lumber yards delivery trucks and my bosses Duramax every once in a while.

 

I prefer open, unless I had an air locker. I think it's safer for winter highway driving. My brother had both rear wheels break loose at 100k on icy roads and it lead to him rolling the truck. I had a limited slip on my '89 2wd and that thing was impossible to steer in the winter it would just push straight ahead.
