Poison Spyder Bombshell Diff Covers are designed to protect your gears, lockers and diff cover bolts from the most punishing rocks and trail hazards. The stock covers your Jeep came with are weak, stamped sheet metal. 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" 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" to a brutal 1/2" thick at the outermost surface.

Differential cover for 2013 Jeep JK

Everything is just as describe. Shipping was fast, cover packing was great and everything was accounted for and undamaged. Cover is super heavyduty and a great upgrade. After comparing prices, 4WD had the best deal and shipping. Highly recommend the upgrade and 4WD.

the Jeep Forum claims that there are very few, if any Diff. Covers that will work on a front TJ differential. is this true? does anyone know of one that will work without modifications? I hear maybe the "Zone" diff. cover may work?
