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:
- Fits Ram models with leaf spring suspension only
- For coil sping suspension models, search our site for MH-AA14-115_CS
- The Mag-Hytec cover has 12 bolt holes instead of 14 in order to accomodate a drain plug and temperature sensor port.

Fit perfectly and very complete set of parts
Had everything I needed plus some extra parts in the kit. I probably could have just replaced the impeller for slightly less but while everything was disassembled you might as well replace the works. Included - Water Pump Impeller, Housing, Key, Face Plate, Face Plate Gasket, O-Ring, Seal Face and Carrier Assembly Oil Seal

Good quality, but could have used better instructions
The kit was complete, and all the components were well made. However, if you aren't somewhat mechanical, it would be fairly easy to install the gaskets and backing plate in the wrong sequence. With better instructions, this would be a 5 star plus kit.

Don't pay boat shops for over priced services!
Boat shop wanted $400 dollars for a new water pump replacement. Got this on Amazon and watched a few utube videos. Took less then 2hrs to take apart and replace. I put it in a Alpha 1 gen 2 lower. Very simple process.
