      Description

      Impact-Resistant Differential Cover. Protect your ring and pinion gears whenever you go off-roading in your Jeep Wrangler with the B&M Dana 30 Nodular Iron Differential Cover. This nodular cast iron cover features a ribbed surface to further strengthen the cover against hard impact. It fits Dana 30 axles perfectly and follows OE specifications to allow for prescribed clearance and fitment.

      Provides Convenient Oil Change Access. With the B&M Differential Cover, you don’t have to disassemble the cover every time you need an oil change. You can check the oil volume using the o-ringed magnetic dipstick built into the fill port on top of the cover. And then drain the oil using the magnetic drain plug on the bottom. This magnetic drain plug attracts the shavings from the grinding gears, keeping it away from the assembly. In a way, it promotes a more efficient differential operation by keeping the lubricating oil clean.

      Cast-Iron Nodular Construction. The B&M Differential Cover is a nodular cast-iron cover which features better tensile strength and increased toughness. It’s engineered to withstand impact from rocks, fallen trees, and more. Meanwhile, surfaces are powder-coated in black for an attractive and rust-resistant finish. All these factors make the B&M Differential Cover the best choice for off-roading challenges.

      B&M’s Limited Lifetime Warranty. B&M offers a lifetime limited warranty on their B&M Dana 30 Nodular Iron Differential Cover. The warranty extends to damages from the factory production, such as material and workmanship issues. For more information about the warranty, please visit the manufacturer’s website.

      Application. The B&M Dana 30 Nodular Iron Differential Cover fits 1987 to 2020 Jeep Wrangler YJ, TJ, JK & JL models.

        3 2001 Wrangler - RobertS

        A solid option for lifted Jeeps.

        Overall a solid and classy cover. VERY BURLY and I wouldn't hesitate to bash it against rocks all day long. The dipstick is a great concept, and the drain port is a nice touch. Two things against it though, and I deducted a star for each. Manufacturer QC leaves a little to be desired. The cover I received had a poorly tapped drain port that I had to carefully re-tap the first several threads of in order to install the drain plug without cross-threading. The stainless Allen bolts provided with the cover are a nice upgrade from factory, but one of the 10 provided had severely damaged threads and needed to be replaced before installation. Second issue is that at least with a non-lifted TJ, you can't access the dipstick/fill port on the top of the cover from under the vehicle, kinda defeating the purpose of the fancy dipstick in the first place. The easiest way I've found to get to it is to pull the coolant overflow reservoir inside the engine compartment and reach all the way down to the axle. I don't think this would be an issue with a lifted vehicle.

      Do you only add the Jeep recommended amount of diff oil when you add these diff covers? Some diff covers increase the amount of oil. This is going on a Jeep Wrangler Unlimited Rubicon JL.

      • This will have a minor increase in oil capacity. This will not fit your Rubicon's axle.
