Rear differential cover

[ShawnR]

I tow an RV at max gross combined weight. I'd like to replace the stock diff. cover with one with cooling ridges and perhaps a little extra capacity since it gets hot. Any suggestions are welcome. I'm trying to not spend $250 for the mag-hytech if possible.

Ta Performance makes some nice rear end girdles. I use their GM 9.5" version.

I put the aluminum one from Summit. It added some more capacity for the rear diff fluid, and it looks cool. The price was also good.
