Locking rear diff mod
Hey everyone. Was wonder if anyone has tried the locking diff mod from spe diesel so you can use the locker above 25 mph. Says it works for the f150 as well. https://www.spediesel.com/collection...-lock-diff-kit

Other than for maybe spinning the tires in snow or mud, why would this be beneficial? I am genuinely interested. To me it seems like it might be a recipe for the back end sliding all over the place.
