Poison Spyder Bombshell diff covers are designed with the singular goal of protecting your Jeeps gears, lockers and diff cover bolts from the most punishing rocks and trail hazards. The stock covers your vehicle came with are weak, stamped sheetmetal. Even a moderate tap with a rock can cave it in against your ring gear, causing potential damage to the gears, locker and carrier bearings, not to mention a difficult, messy trail fix. Even more common, though less catastrophic, is peel back that can occur when sliding over a rock causes the lip of the cover to peel up, allowing your gear oil to drain causing a hazard for both your Jeep and the environment. The Bombshell Diff Cover is your best insurance against each of these hazards. The Bombshell differential cover is cast from highly ductile nodular iron—the same material drag racing differential housings are cast from to handle thousands of horsepower. The design of the Bombshell incorporates recesses to protect the diff cover bolt heads from trail damage, while the profile of the Bombshell acts as a ramp to help slide your Jeep up and over the most troublesome pumpkin-eaters. The ramp profile also results in an extremely thick & up to 1 inch thick—cross-section around the bolt ring, where contact with the rocks is most likely. Throughout the rest of its cross-section the Bombshell is the thickest cast differential cover on the market, from 7/16 inch to a brutal 1/2 inch thick at the outermost surface.
Wish it specified better that the non coated will rust immediately. If I would have know, I would have bought the powder coated.

Perfect fit, looks great
The front and rear covers fit perfectly on my 2012 Rubicon Unlimited with a 2.5" lift and did not contact the front or rear track bar. The fill hole is a little too high for the front Dana 44, so fill by volume. I bought Felpro gaskets instead of using the gasket maker. I put anti-seize on the bolts and torqued them to 24 ft lbs.

Tough diff covers!
Have these poison spider covers on a few different axles now (d60, d44, d30) and they are great! They look trick and are very strong- literally almost a half inch thick nodular iron! They also have a pretty low profile for clearing beefy steering component. Had always fabbed 3/8" steel covers in the past, but after seeing one of these covers in person I decided for the price I would start buying these and using my time to fab other things haha.

Protection as described
I have this for my front Dana 30 and rear Dana 44 (different part number) I have had them on for a year now. I have not only bumped them on holders but did drag them across. No damage no leaks and hold up strong. I also combined these with the lube locker gasket instead of rtv and they are still holding strong

Dana 44 Bombshell
The only thing bad I can say is the bolts that come with the covers are not good. I snapped off a bolt at just over 25lbs of torque. This is the only reason I rated at 4 stars.
