Rear differential covers

I’m getting ready to have the rear diff serviced and am considering adding an aluminum cover with heat sink. Have you gone this route? Does it make any significant difference?
I have 155,000 miles on my truck and looking at a leaking pinion seal. I have changed the synthetic lube every 40,000 or so miles. Not sure the cover would be worth the $300.00 for it.
Your opinion?
Thanks!

    But I'm too cheap to look nice.

    If casting fins into the housing cover solved any problems, wouldn't the manufacturer be doing that already?

    For what they charge they better look nice, $200 for a couple of pounds of stamped aluminum is overly expensive IMO.

    Considering adding a cover for differential protection and/or heat dissipation...after 155,000 miles? And no protection and/or heat related issues? Hmmmm. Why?
