I havent shopped around yet because it will be about another year before I really do something.

 

It just sucks that the LSD isnt what its cracked up to be. Hell Id hate to see how horrible the traction are on the open diffs. Im adding a body lift and toyo 35's , so Im hoping my stock size tires is one reason by I can never get a grip. Even so Im definitely upgrading the LSD before the years over.

 

Our LS isnt much better then the open diff. My wifes 05 Tahoe walks all over my truck. It sucks that we spend so much money on our trucks and more for the LSD and we have to swap it out right away.

 

Yeah your right, it does suck... The LSD money pit haha, Impressive truck you got there tho! I love the look of The new F150's, SHARP!

 

how are the GM LSD's compared to the Ford's LSD? I know the SUV's do really well, but thats because of the added weight. Do the GM pickups with LSD perform alot better than the Fords or are they pretty comparable?

 

Thanks, Your truck is pretty sharp too.

 

To me the GM (at least my wifes Tahoe 05 and my last Tahoe 97) pulls much better in snow and sand. The lsd works a lot better then fords. But I think the fords are a lot stronger build minus the LS. Both trucks have there + and -. Ive been off roading with my cousins H2 Hummer and that is awsome off road. It sucks that I have to spend a great deal of money just to get my truck were it should be.

 

my 06' lariat has LSam I going to run into problems next year in the snow? if so what should I upgrade keeping in mind I'm poor and don't wanna change the appearance of the truck?

 

Hey I have an '02 FX4 and it's got a code 19 which is not LSD according to the table earlier in this post, is it just the newer FX4's that have standard LSD?

 

No not at all. Im poor also lol. My mod come one at a time and are spread apart.

 

I drove GM LS's for years. They seem to react quicker than the Fords but you get into the problem of them shifting power from one axle to the other frequently and quickly, not enough time for power on one axle at a time to make a difference. And then there was always the "ratchet clunk" you would hear when turning a corner on a GM LS. The Ford's seem to have a slower reaction time and takes more power to engage the LS but I don't hear the "ratchet clunk" when turning a corner.

 

I agree! I have the 3.73's with the factory limited slip diff's in my 07 super crew XLT 4x4. One time while offroading we came across a patch of ice out in a field. I stopped right in the middle of it while in 4x4 low, not thinking anything of it. When I went to take off... NO GO. While it was still in gear, I hopped out of the truck and was watching the rear right and the front left tire spinning very slowly (still in 4x4 LOW and in Drive) but the truck is not moving. I thought that the limited slip diff's were suppose to avoid this exact situation. Ever since then I've been planning on putting electric lockers in the front and rear, but I can never seam to come up with the money, it's something like $1800 for both installed.

 

I'm looking at a 2003 F150 for sale. It is a Lariat 4x4, but not a FX4x4.
How do I identify whether it has the limited slip.
I saw one post say the door pillar - 19 or H9 - does this mean it has or doesn't?
Thanks,

 

This is one of the reasons I havent done it yet. 2k to install something I paid extra for at the dealer.

 

19 is non LS. if it's H9 it has a LS diff. it's a pretty obvious sticker in the pillar, good luck man
