With all of the monstrous accessories bolted to your trail rig, one part stands out as an obvious weak-link—the stock differential cover. Rolling around with a flimsy cover is just asking for a boulder to empty your rear axle’s precious gear oil. So, unbolt the weak, stamped steel diff cover and replace it with a ready-to-rock cast iron ARB differential cover. Loaded with rugged features and unbeatable strength, ARB diff covers are sure to guard your rig from oil-emptying boulder bashes with ease.
