What "anti-spin" is in Dodge axles?

[RickyR]

I have a buddy, who has a 1999 Dodge 2500 extended cab 4x4. I believe it has a Dana 60 vs. a Dana 70. I haven't pulled the axles to determine the spline count. My question is, what is the anti spin differential in this axle? And, what are the chances it is a 35 spline?
BTW it is a 4.10 geared axle..
Thanks, Ricky...seeya...

It should be a 'track-lock' LSD.

"Anti-Spin" is Dodges terminology for LSD . If your rear axle is a Dana60 than it should have a T/L but if it is a Dana 70 it will be a P/L and it will be 32 spline .

What about a Dana 80?

[v10sport]

80's are 35 spline
What motor/ Tranny does the truck have?
As said before, if its a 70 It is a powerlock L/S

[desertCJ]

It is a 24V Cummins with NV4500....it says 80 right on the axle. The invoice sticker says it has 4.10 R+P and a limited slip.

Tom,
Thanks for the info.. It is a D60 for sure... Will it be a 30, or 35 spline axle?
Thanks again, Ricky...
BTW it is a gas engine.

[v10sport]

60's are 30 spline

[GRMhick]

if its a 2500, it uses a dana 70/80 hybrid. Meaning it has a dana 80 cnter section, with dana 70 35 spline tubes, hubs, and shafts. 3500's get the 37 spline dana 80.

If it's a gas burner it shhould have a Dana 60 in it . I am not sure about if the 60's came with 30 spline or odd ball Dodge only 32 spline just like the 70's that came in the auto diesel 2500's . I do know that it will not have 35 splines axles in it - sorry . The best way to be certain is to pull a shaft and count the splines , there just aren't a whole lot of rear Dana 60 equiped 94 and up Dodges out there.......

HTH's , Tom

I just re-read the post's up above and it looks like V-10 Sport called it to be 30 spline - I read a whole lot more than I post and V10Sport seems to usually be correct so I would go with what he said if you can not pull a shaft.

I have not seen any 3500's with anything but 35 splines in the Dana 80's . The large 37 splines are standard fare for the Dana 80 in trucks stouter than 1-Tons but as far as my knowledge goes all 1994 to 2002 Dodge 3500's Dana 80's came with 35 spline side gears just like a Dana 80 equiped 2500.

and 360 powered HD trucks got the d70 rear.

Not my friends `00, definately a 60.

[GRMhick]

As I said, the heavy duty trucks. I think tis the ones with the camper tow package.
The standard dodges got 30 spline 60's, and older trucks got 8 lug 9.25".

Interesting ... I have only seen a handfull of BR2500 H.D. 360 powered trucks and all have had Dana 60 rears .
To the best of my knowledge the L.D 2500 that had the gay eight lug 9-1/4" s/f stopped production shortly after the new body style came out in the mid ninety's - after that all 2500's were H.D.'s .

My 2002 Helms Manual shows the Dana 60 rear axle being offered on the H.D. models trucks too.

Ive seen a few HD v8 2500's and have never seen a 70 in them.
Only thing Ive seen a 70 was auto V10's or diesels

Edit, Ive seen 60's on the camper tow package also.
I had this package on my truck and all it was a rear sway bar on overload leafs
It was a 75 dollar option

I ordered the "Camper Pep PKG" on my 2500 and all it consisted of is the over-loads and the rear sway bar too. I think it was $180.00 when I ordered my truck .
As far as I know the axle does not get upgraded when the "Camper PKG" is selected - just the extra springs and sway bar .

I've never seen an 8 lug 9.25. I have heard they exist, but never seen one. The 1972-1993 3/4 ton Dodges came with a D60 rear axle, whether 2 or 4 wheel drive. The 4x4's came with an 8 lug D44HD in front, the only part better than the 5 lug version is the bigger brakes. Same axle housing, and 1985-1993 were CAD.
The 89-93 4x4 3/4 tons with the Cummins had a D60 front.

[steved]

If it is a D70, it's a powerloc. If it's an D80, it's a two-piece tracloc. If it's a D60, could be either a tracloc or a powerloc...I have seen both in the newer trucks (someone might have swap one or the other in though).

They made those eight lug 9.25s until around 96 I think. They were termed a standard duty. I'm with V10sport, the 2500s with a V8 (manual or auto) have a D60, auto backed V10/CTDs got D70s, manual backed V10/CTDs got D80s.

And the D80 in the 2500s is a hybrid with a D80 center and D70 outers. We used bearings and seals I bought for spares for my D70 in my dad's D80 hybrid. I didn't count splines.

The camper package is simply overload springs and a rear sway bar. In the 1970s/80s it gave you a bigger rear like a D60HD instead of a D60. But mine was purchased with a camper special and it was noted as being springs and a sway bar for $180. The LS was $285. The 4.10s were like $55???

Some of the mid/late 80s and early 90s D/W250 dodges used a semifloating eight lug 9.25 inch for the rear and a D44HD front. They used the D60 and eight lug 9.25 interchangeably for some time...you didn't get a choice unless you optioned for the D60F (more GVW capacity) then you got the D60 rear.

And from 1975 to 1993 you could option a D60F in your W250 if you wanted by upping the GVW of the package you purchased. Prior to that was a D70F with closed knuckles in the pre-75 trucks.. CTDs did all have the D60Fs/61Fs.

The dodge D44HD used the same brakes from what I have seen but they were eight lug and early versions were 1/2 inch thick tubes (versus later 3/8 inch thick tubes like a 1/2 ton).

And the 89-92 CTD could also have been equipped with a D61F which was found behind the CTDs equipped with a 727 auto...they were 3.08 gears. The 5-spds came with D60Fs with 3.55s or 4.10s.

94-97/98 Dodge used a power lok in the D80's i have had two of them in 98 they went to the bolt together Trash lok that you correctly identified as a POS and everyone else likes to call a power lok.

Not sure about the 32 spline count on the D70's my books show the D70's with 32 splines ending production in 1993 and that D70/80 axle shafts interchange from 94-2002. Some must have come with 35 spline side gears in 97 because my last powerlok that i robbed out of a 1997 diesel D70 only required minor maching to make it fit my D80 hybrid didnt even have to change side gears. so 35 spline is what they were.

[v10sport]

All the 94 to 02 Dana 70's are 32 spline. Ive had the shafts out of 3 or 4 of them V10 an 2 diesels and all 32 spline. Mine is 32 spline also. ARB and Detroit also list the 94 up Dana 70's as 32 spline
