Ive got a "Perfect Launch" rear diff. cover made by Proform but havent installed it yet. These covers have the 2 bolts that stabilize your bearings. They also have the drain and fill plug in them and are somewhat stylish. A bit on the pricey side at around $150 for our trucks. I will give some feedback in a few weeks since mine is going to be installed along with my new gears a week from Friday.
