Back in our April '03 issue we smashed a bunch of diff covers, and one of them was from Off Road Unlimited. Big Steavie at ORU took the loss to heart and decided that it was time for a serious diff cover made of nodular iron instead of aluminum. What you see on the left is the new 1/2- to 1-inch-thick Big Steavie Cover by ORU for our front Dana 60. For the rear axle, we went with a 1/4-inch-thick diff cover from Wagoner Machine Shop for our Corporate 14-bolt. These are important upgrades since some of us are not used to driving fullsize trucks and will most likely be ramming the diffs into plenty of obstacles.
