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.
Excellent quality product, and Greta customer service.

5.0Solid product and customizable.
Awesome product that just works! Protect your ring and pinion gears in style. Also very easy to customize the look by painting the Spyder a different color.

Impressively robust diff. cover but the bolts are sure disappointing. One of the bolts stripped out before I was even close to the torque setting. I contacted 4WheelParts and asked for a replacement bolt and they told me to go to a hardware store. I don't feel that is very good business.
It’s heavy but I guess to install. I paid someone to install mine.

3.0It will rust!
Wish it specified better that the non coated will rust immediately. If I would have know, I would have bought the powder coated.

Stock differential cover, just had $1500 worth of steering work done at your Copell Store. My track bar is scraping my differential cover. (I run offroad with the sway bar disconnected)
1) what's the fix to this issue? (Hopefully without spending too much more money)
2) will this differential cover be compatible? Or am I just going to be scraping even more?
Answer this question
It will rub more on the track bar as this cover is a little thicker. Some of the track bars have more of a bend to clear the covers. You might check with the Coppell and see which bar they used.
