Bombshell Diff Cover - Dana 30 - Black PC

  • $104.00


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 4X4 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 4X4 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. The sealing surface has been CNC machined flat for a perfect seal. Poison Spyder provides a tube of silicon sealant and new Grade 8 hardware so you'll have everything you need except for tools and gear oil. Note that Bombshells are thicker than the stock sheet metal diff covers, and as such may have interference problems with stock components on certain vehicles. Jeep JK's and TJ's, for instance, in which the stock track bar is still present, may rub on the Bombshell under full suspension compression (most aftermarket track bars that come with quality suspension kits solve this problem as the track bar does not hug the contour of the differential so closely). This item ships with a semi-gloss black powder coat finish.
