Dana 60 gear oil capacity.

just pulled the aluminum LPW cover off my d-60 to check things over and cannot remember how much oil I need to put back in ,this cover has no sight plug for the correct level just a drain plug and a fill plug up at the top, I have 2 1/2 quart in it so far, how much are you drag racers running in your's?

1 and 3/4 here..with a plain steel cover

3 qts with the LPW cover.

Drag only? 2 quarts, if that.

The Mopar engineers that use to put on the drag seminars always recommended 1 quart gear oil max in both Dana 60 and 8 3/4 as already stated, that was for a drag only car.
I would run around 2 quarts on a street car just to be safe

ok guy's 2.5 quarts should hit the happy median then, thank's to all,, PS, the gears still look great after 14 plus years of abuse.

Mine has a LPW cover. There is a level plug on the right side. 3 qts was still below that plug. What I did notice running lower levels before is that very little lube was in the axle tube. Mine had a little surface rust on the axle shafts. So this time I upped it a little. Don't know if that will help. We'll see.

It really depends on the cover - a stock cover is usually about 2 1/4 to 2 1/2 quarts - some of those cast covers hold a little more

This cover was bought as a Jeg's house brand, no level plug in it, maybe that is why it was less expensive than the LPW unit altho it had the Ultimate 60 cast into the center outer cast in bracing and bearing cap tensioner bolts, adding another 1/2 quart would not bother me.

Wasn't there a thread on here a while ago about most of those aluminum covers causing oiling issues compared to the stock cover?

I think the consensus was they weren't that good for the street, by the looks of how mine is doing they seem to be ok for drag racing as mine has been on since I built the dana 14 years ago,,,same pro gears and bearings

I always put in 2 quarts in the dana 60

Stock cover, two of these

The LPW cover has a shape conductive to fluid flow. However really no need for a braced cover on a street car. Fill the fluid to the bottom of the tube (less for drag only if you wish) and you'll be fine.

Mopar factory spec is 2.75 quarts..

Just my $0.02..

Cab, wouldn't there also be a level difference between a spool and a suregrip?

2 quarts in a street/strip in a Dana 60. No more needed.

They didn't recommend more or less with a spool or posi

I have had an LPW cover on mu Camaro's dana since 2001, It is a street car that sees the racetrack once in awhile. Not one issue with the gearset or bearings at all.

Because they had shelves full of spare parts and we're competing in stock/super stock. Gear life wasn't a priority.

Whatever the service manual says is what I follow. I've never lost a race because my rear end fluid was slowing me down.

None of the Chrysler Engineers “raced” a car in competition. They didn’t have shelves full of parts. Mopar did though.

The Seminars never promoted anything that would cause damage or affect durability unless they prefaced that with a warning.

I seem to remember several different Hemi cars that the race group engineers used for testing 1968 Charger and several different A bodies along with a bunch of other pro stock type cars, IE Don Carlton Hemi Colt for Comp Eliminator

Read my post again Cab, they used cars for testing but they never “competed”.

I never knew any of the guys that would make a statement that would lead to failures.
And I knew all of them.

As with many other things, what the factory manual says and/or recommends is not really relevant to a vehicle used exclusively for drag racing. Drag race rear ends are not subject to one of the main causes of gear oil breakdown and rear end failure, heat. Nor are they expected to reliably be ran for 100,000 miles, likely with the same oil it was put together with.

I will back to back test 3 qt's vs 1 qt. And report the results when I hit the track in April.

Looking forward to the results of this test!

Doug won’t see any improvement.

He’s making too much power.

Now if he was running N/SA with a /6 he may see some improvement. 😂😂
