5.0 Mag-Hytec rear diff cover for duramax

Mag-Hytec is a cut above...their products not only add style but improved function above stock equipment.

5.0 So easy a child could do it!

I purchased these covers for replacement on my 2005 1/2 Dodge 2500 Diesel six speed. I have back trouble but insist on doing my own maintenance, having a lack of trust and being a penny pincher. Fluid level check is as easy as screwing out a dip stick. When fluid change is needed, unscrew drain plug and completely drain fluid due to extremely well designed location in the cover. I plan on changing the diff. fluids every 75,000 miles. This will make the routine fluid checks and eight fluid changes I plan to need simple enough for a child to do!

5.0 Mag-Hytec Diff cover for GM

I installed the Mag-Hytec Differential cover on my 2008 GMC Sierra Crew 2500 4X4, with the Duramax Diesel and Allison 6 speed trans. I tow a 38' 5th wheel and know that the rear ends take a lot of abuse. Think about this point, your differential is the center point of all your Horsepower and torque. All of your power is concentrated to the ring an pinion while driving and generating heat, especially when towing. The heat that is built up is incredible in the stock configuration and the Mag Hytec cover allows for better cooling an heat dissipation. The cover is larger than the stock cover and holds almost twice the volume of oil which also aids in cooling effect. Things I like best about the Cover are: - Easy to insall, took about an hour - Easy to fill with fluid - Looks Great - Allows me to check the fluid level easily - Gives me peace of mind knowing that I don't have to worry about the diff anymore. GREAT PRODUCT, I'd recommend to anyone with a truck.

5.0 Awesome

Installed on my truck with no difficulty. A good torque wrench is a must. Comes with 1 extra bolt cause like me you will break one. Made towing noticable quieter and cooler on the rear diff. Looking forward to adding the trans pan next.
