Limited Slip vs. Locker

I was looking into a locker and or limited slip... what is the difference? With the limited slip will I still be able to do burnouts / donuts?

Im sorry if this is a stupid question haha Im just concerned I won't be able to have any fun with a limited slip.

Do you off road or do you not off road is the question?


You can still do little burnouts with a limited slip

what i was told is that a limited slip it not the much better than a open diff... i tried flexing my truck with a limited slip and i had tire spin on the light side tire.... i also heard that jus say if you were on a rock and one tire was off the ground you would roll backwards... imp i dont thinks its worth getting a limited slip... i would get a locker.

The way I typically see it, LS for a truck primarily street driven, and a full locker for a truck that's spends Alot of time offroad. If you get a LS you should try for a gear driven LS rather than clutch plates.

if your that worried about doing burnouts and stuff then get a air locker so you have total controll when it is locked and unlocked... that jus a pricy way to go

Put it this way with my stock L/S I could roast posi on my 36's. Unless you are seriously into offroading I would go L/S.

Not really true. My stock L/S never left me spinning one tire, in the front or rear.

and the posi in the 9" is working better with the Lucas in it, but if a tire is completely off the ground its useless.

Yhea well stock L/S isn't all that strong anyway. I think I was more less just lucky mine was new and never got worn out.

A limited slip is all but worthless offroad. On road is a different story.

Not true have you ever gone from an open diff to a limited slip?

agree with you completely i can smoke my 31s easy with the limited slip in the stock explorer axle.

I agree again, A open to LSD is a HUGE difference in off road performance. While not that of a locker, but figure i paid $75 for my rebuilt LSD. It was well worth the money.

I've yet to be left down by the LSD unless I had a wheel off the ground. Other than that, it has worked very well for my truck, and my wallet. I will upgrade to a locker at some point, but in no way was the LSD upgrade on my truck a waste of money. It was money well spent!

Well I am 2WD... I dont plan on doing a ton of offroading but I do do a lot of street driving... but I would also like to have the capability of going off road and having traction in the mud and trails... limited slip still okay for that?

I do have concerns about the price of a locker... thats why Im looking at the limited slip.

In mud, sand and climbing hills I never had a prob. with l/s. Now in South Jersey I don't have any rocks to climb I figure it wouldn't have did much for me there.

Like in this pic I spun posi in 2wd to dig my self in then spun all 4 to take the pic before backing out of it.

you guys lovin your LS axles need to get a spool or real locker, then you'll hate your LS ha..

sure an LS in sand and mud are alright, but once you get into technical dirt trails, with mounts or rocky trails your in for some trouble.. especially wet rocks, those are always fun.

True but every situation is different. Those who are willing to put up with more aggressive street driving for off road performance will love the locker or spool. Those who head off road maybe once a month or two will benefit most from the LSD. Most non V8 or n/a street trucks will be happy with the LSD

If my ranger wasn't a daily driver I would have had the rear locked and an air locker up front.

you can still get an air locker up front, it doesnt effect your tires on the street.. but i dont think ARB makes one for our front axle do they?

My truck being driven on the street everyday is the only thing holding me back from spooling the 9"

Like pretty much everyone said, it really depend on what you are going to do with your truck. I have an air locker and I LOVE it, but if you are just going to do light trails, sand, and street driving it would be a waste. I don't like limited slip at all, because I like to know that both tires will spin.

Not sure if they do make on for our trucks front diff. or not. I never looked it up, if I started looking for one I'd of ended up spending money I didn't need to spend.
