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.

Your vehicle's differential plays an important part in its performance. This component is the chief reason your vehicle can turn or corner, but it's also vulnerable to damage if you frequently drive off-road. Whether you ride over rocks, logs, boulders, thick underbrush or other trail obstacles, differential covers keep these parts in top condition. Avoid letting your 4x4 get sidelined by serious damage from these hazards. Install a Poison Spyder diff cover sourced from 4 Wheel Parts, your source for top-quality off-roading gear at the best prices.

Top-Notch Protection

As great as your 4x4 is, it came off the assembly line with stock differential covers. While they're made to meet manufacturer's specs, they can still suffer damage when you're out on the trail. If a moderately-sized rock can push a dent in a differential cover, imagine what kind of damage a huge boulder can cause. When your gears, locker and carrier bearings take a hit, your riding adventures grind to a halt. Differential problems can manifest in a wide range of symptoms: whining or howling, slipping and jerking transmission gears or burning smells from your gearbox.

Crafted from highly ductile nodular iron, the Poison Spyder diff cover Dana 44 offers rock-solid protection from the brutal hazards of the trail. The Bombshell is the thickest cover on the market, spanning from 7/16" to 1/2" thick at its outermost surface. A black powder coating gives the Bombshell an attractive and durable finish.

5.0 Solid 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.

3.0 Cheep bolts!

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.

5.0 Bombshell cover

It’s heavy but I guess to install. I paid someone to install mine.

5.0 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.

4.0 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.

5.0 azpacer

Has taken some big hits and keeps on protecting. I was surprised to find something this strong at this price.
