A front limited slip for 98+ 4x4 Rangers. Torsen is the brand, T2 is the line of limited slips. Been in the works on and off for the past 3 years or so.
Currently, the only traction aid avaliable for our front M35, is an Aussie Locker, which is quite violent in 4wd.
And before anyone says 'it's worthless to do anything to an IFS', you can go ahead and hold it in. Good for you that you've got a solid axle, but you know, tons and tons of us certainly don't need one or even want one to get done what we want to get done.
