Mag-Hytec Rear Differential Cover | AAM 14-Bolt 11.5" | 14-18 Ram 2500
Description
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!

Q&A
- Does this clear the sway bar or do mods have to be made?
- Yes, this is intended to work with the factory sway bar without modifications. - AW
- Do you have to drop the rear sway bar for install? Also there are 2 brackets that are on the OEM diff cover, will those be relocated or where do they go?
- Yes you have to temporarily drop the sway bar for install. The brackets are taken loose from the stock fasteners and moved out of the way. Then reinstalled with the new hardware with the new cover in the same spot. DPPSands
