This is one of those things that you have to have if you're going off road. The OEM front differential cover is soft steel and the lip is vulnerable to even slight impacts on rocks. Protecting the cover and silicone seal is as critical as the 4-wheel drive option on your Dodge Ram truck. Critical Differential Protection
- You never know when you'll need it. Shown below is what you might have to do if you graze the top of a rock while off roading.

This incident here was just enough to break the seal and let the gear oil leak.. an event that could cost hundreds of dollars at a gear shop Proven Performance
- During testing in Baja, one of the trucks outfitted with a prototype took a boulder at 12 o'clock... an impact enough to stop the heavy truck, dead in it's tracks. The result? Mere scratches on the rattle can paint job and the quarter inch thick steel triangulated design held up to a severe blow. This is the kind of front differential protection you need when you step off the pavement.
