Limited Slip

How do I know if I have a limited slip differential?

I just ordered a new "Mag-Hytec" Differential cover for my rear end, and they suggested that I get "friction modifier" if I have a limited slip diff. I wasn't sure so I ordered it anyway.

How do I find out if I have limited slip?

get both rear wheels off the ground and spin one.. if they turn the same direction you have LS, if they turn opp directions than you dont>> you can buy that friction modifier at any auto parts store so i would recommend ordering it just in case

Look at the tag on your rear diff. It should say 373ls or 410ls on the tag. Those letters are your gears and limited slip note.

Limited Slip

From the SD Frequently Asked Questions Page:

http://www.clubfte.com/users/monsta/...hassisFAQ3.htm


Q: How do I know if my truck has a Limited Slip?

A: On the tag on the rear axle you will see the gear ratio. If you have an L between the first and second number, then you have a LS unit. You can also raise the rear wheels and spin one wheel. If the other wheel spins opposite then you have an Open Differential. If it spins WITH, then you have a Limited Slip.

Not true.......I don't have the off road package and I have the limited slip rear.

The limited slip was an option with the ring and pinion gears,,,it was not dependant on ordering other packages as well.



Hope this helps.

Limited Slip

Yes I do have limited slip both wheels turn is the same direction and I have an L on the rear end tag. Found out yesterday when installed a new "Mag-Hytec" diff. cover. Very easy to put on and I didn't spill a drop of oil when I filled back up becuase of the easy dip stick/fill hole.

Thanks for your help guys.
