I was just going to order a Mag Hytec rear diff. cover for my 3500 4x4, and all of a sudden I flashed I have 2 diff's, front and rear. Did you guys that changed out your stock ones do front and rear both ?? I'm not working the front like I am the rear thats for sure, and I really don't see a need for the front. I do alot of towing and know the rear is a must. The stock one is already showing signs of heat, by the paint bubbles.

 

i had the front one but it wouldnt fit with the dual stabilizers

 

I hear the front doesn't fit very well and makes contact with the track bar. I would get the rear only. If you really want the front also look at the PML. I don't think it hits the track bar.

 

WOW ! Others please help here but I am thinking you may have issues if your paint is bubbling from heat on your rear diff! It should never get THAT hot.
