Hey, I have an 03 B3000/Ranger 3.0L V6, 2WD, 5speed, I currently have a LSD, but it isn't working very well. I'd like to switch to a rear locker, but all the ones I've looked at say they will not fit in an LSD housing. Does that mean there aren't any that will fit?

 

you need to find a wrecked ranger rear diff that has the open carrier( with spider gears )

diffs with factory lsd`s will not accept a locker of any kind

 

 

I dont think this is entirely true...

 

You are looking at lunchbox lockers that require an open differential to place them in. You could always have your clutch packs replaced in your current rear end, or look into an auto locker like the Detroit Locker, or an electronic locker such as the Auburn etched, or Eaton E-Locker. These replace the whole carrier, so they will work.

 

How much would something like that cost me? And where would i get those parts

 

i meant to say that the LSD itself cannot itself be upgraded to a locker

but the axle housing itself can be upgraded with a locker installed if the owner wanted to install the lock right locker guts

i am sorry for the confusion

 

Ford/Mazda installed 7.5" or 8.8" differentials in these trucks

All 4.0l engine trucks got 8.8", that started in 1990
3.0l engine could have either.

And Limited Slip was an option on either size, so you first need to know what size differential you have.

Ford calls their Limited Slip differential Trac-Lok, GM calls theirs Posi-traction

Both use clutches that will "slip" when cornering allowing wheels to turn at different speeds.
Both also need additives to allow this "slipping" or clutch plates will shudder.

Any "auto" locker, like above, will be the same, 3rd party cost more and tend to be better, but there still isn't positive locking.

Then you have manual lockers, these are manually activated, these act as an open differential until you turn them on, then axles are locked so no going around corners on hard surfaces, lol, but you will have equal wheel power on both wheels when locked.

With a 2WD truck I am not sure what you are after in the end?
If you need both rear wheels locked while going in a straight line then manual lockers are what you want.

If you will be driving on slippery roads, i.e. snow/ice, then auto-locker might be better choice, and rebuilding your Trac-Lok might be best option, or a Detroit Locker
