Cooling Differential covers, do they really matter?

[85_Ranger4x4]

Once upon a time there was a comical glitch is the universe. You could get cast aluminum MOTORCRAFT Shelby GT-500 differential covers online for like $60, Ford Performance ones were like $200. Same part, one was thru their replacement part system and one was thru their upgrade accessory system. So I snagged one. Diff cooling needed or not, Ford came up with this apperatus for the Shelbys.

I found a plug to plug the hole for the temp sensor and while I haven't yet I have the block off ports for the cooler lines for a drain plug and the top one to flush out the case if need be.

most interesting!

I cant see a rear end getting hot unless youre loaded super heavy and constantly on the go pedal.

The semis have rear end temp gauges....even on 100* days hauling 50k of milk at 70mph i think ive hit 180.

Even the manual trannys have cooling systems on them so i would think if there was a real benifit to a diff cover like that they would have them.

Ay that's the thing I was talking about!

Looks like it has an electric pump attached? I'm curious where you'd find power for it with the correct voltage all the way back there.

I did just recently spend 2 hours at the trucks speed limit of 90 mph with around 600lbs of payload (not a lot I know, but more may be coming. I may actually try attaching a thermoprobe or otherwise a method of measuring temps after the next trip.

There is a sensor that goes in the cover so I assume there is wiring back there for it.

I put a normal metric pipe plug into that port and just use it as a cover. I am throwing less than a third of the hp at it and was mainly tired of my steel cover seeping and having no ability to drain the diff after water crossings.

I also had to knock down some of the internal cooling fins because my old Explorer axle has a tone ring than the Shelby wouldn't have.

Well, if you still have all that jazz and I find myself heading across the border I may be interested in picking it up for the sake of science! Sweet deal you got there.

I only bought the cover for $60, I have never even seen the rest of it in real life.

My mistake, I thought you had snagged the cover + the cooling doohickey for 60$. That'd be a deal!

 

[superj]

there is an 8.8 finned cover on marketplace right now for 60 bucks. i think it was a banks, too. i will have to search for it and hopefully remember to post it

 

[superj]

I was wrong. There is tons of diff covers but the two 8.8 ones i was mis-remebering are ford motorsport 8.8 ones like pictured above. 200 bucks which is a nogo

get an IR thermometer, like the ones that measured foreheads during CIVID.
they have automotive compatible models for hi temps.
can be used on exhaust ports to find a poorly performing cylinder and other stuff.

they are not expensive and super easy to use because you don;t have to bend your wrist in all kind of directions to get measurements
