Re: Differential swap on 8.8 explorer rear end.
You can add an extra shim/spacer behind the side/spider gear, this makes it act like a limited slip. As you can see, the spiders aren't as big as in the trac-loc so are weaker. This set up should last 10,000 miles.Depending on how much traction you get, and horsepower, you could blow up the spiders. I did this with a 9" in a Torino with a stock 429 and had no problems BUT had no traction; so no shock loads to the rear end. Re-read your post and it sounds like this is what your going to try ?
