Constructed from high-quality cast aluminum right here in the USA, this differential cover from Mag-Hytec keeps your differential remarkably cooler than your stock cover. This dramatic increase in heat dissipation happens for three reasons: First, the cast aluminum deals with heat in a vastly better manner than the stock steel pan. Second, Mag-Hytec designed the cover with external cooling fins to get rid of heat fast. Third, this cover holds more fluid than stock. Cool, dense fluid is always a good way to keep temperatures under control. The combination of cooling fins and additional fluid make for an exceptional upgrade to protect your differential.
Mag-Hytec also made sure this cover comes with a host of other features. To keep your fluid clean, the cover comes standard with a magnetic drain plug--designed to pull harmful ferrous metal particles right out of the oil long before they have any chance of hurting your differential. Next, the cover features a pre-tapped 1/8 NPT port for those who wish to install a temperature probe--capped with a stainless steel plug when not in use. Finally, an o-ring is used to seal the cover instead of messy sealant and gaskets. This cover allows you to drive your truck hard without fear of heat damage!
IMPORTANT NOTES:
- This cover typically fits Ram 3500 models with Max Tow and with leaf spring suspension.
- For Ram 2500 with coil sping suspension, search our site for MH-AA14-120CS
- The Mag-Hytec cover has 12 bolt holes instead of 14 in order to accomodate a drain plug hole and temperature sending unit hole

Amazing soap
This is the best soap I’ve ever used to help with my psoriasis and my son’s eczema. It completely helps calm down flare ups and clears it completely leaving our skin soft.

It works!
I can’t believe how well this soap works! It actually relieves the itching and irritation on my neck from eczema. It lathers well and it smells really pleasant without smelling too perfume like. I cut the bar in half so it would be easier to handle. I also appreciate that it is made here in the USA, and surprisingly, it doesn’t dry out my skin like most soaps do. I’m so glad I found this!

Seems to help, but who knows if you only shower 1x a week
Seems to help, not hurt. But I don't shower every other day, so who knows. I will say it melts quickly, way quickly. Might be worth it if you shower every day or so, to get the moisture benefits. For me, I'll just use super moisturizers with Shea butter instead.
