rare Dana 60 parts
 

3.54 geared Dana 60 coil spring rear end. I know some of you think they dont exist but this one if proof they do. Ive sold the powrlok out of it but I will be reinstalling the original open carrier into it this week. $175 . This one has the panhard bar mount cast into the housing. Ive never seen another one on a 67-72.

4 series Power lock carrier for Dana 60 . Fits 4.56 and numerically higher gears with 30 spline axles. Hard item to find to be sure . $200

4.10 Dana 60 gear set . Excellent condition . Free to good home to whoever buys the 3.54 geared dana 60

I know they exist, I have one under my 67 3/4 ton. They were mostly istalled in BB 3/4 ton Suburbans. WES www.ClassicHeartbeat.com

I have one too.. a 3.54 Dana diff from a 70 gmc 3/4 ton coil sprung.

I never could figure out why GM would include the danas in some and the eatons in other similarly equipped trucks. Mine was a big block Close Ratio 4 speed truck when it was new and it and a Dana but I have seen big block 4 speeds that had eatons in them too ? I thought it was maybe the heavy duty rear springs that pushed it over the limit but I have seen C30 1 tons with eatons under them?

I have 3 of those very rare dana 60's, coil sprung and all posi. I had 1 leaf spring dana that came in a 72 GMC 350/4spd.

I have one for a 1/2 ton 6 lug. Totally rare

I dont think Ive ever seen a 1/2 ton dana 60. Not under a 67-72 Chevrolet anyway . Werent they more common in the 60-66 range ? Must be a semi floater. Those must be the basis of those jeep dana 60 conversions I see. Is your 6 lug a leaf or coil Dana ?

Confusing history on Dana 60's. Everyone used them but no one kept good records. The powrlok carrier in my trucks dana came from a 63 ( 1962 datestamp ) vintage truck although all the official sources say they never made a dana 60 that early .

Hey guys,

I don't have any GM documentation to back it up, but from
my experience, every FACTORY Big Block 1/2 ton in 1968
and 1969 that I have ever owned (3) or looked under(couple
dozen) had the semi-floating 6-lug Dana 60 rear axle.
Not to say it was required with the BB option, but I can't recall any 68-69 BB 1/2 tons with the standard 12-bolt.
All BB 1/2 tons from 70 on (first of the wide axles) were 12-bolt.
Anybody know more about the 6-lug Dana 60's???????

Mike

Coil 1/2 ton

Parted 69 BB 1/2 ton truck.had a 12 bolt 3.0's Posi.Parted 68 GMC BB truck 3.5's Dana 60 Posi,67 Dana 44 3.5's thats some junk ive had in last months.

I probably don't see too many 6 lug semi floater dana 60's around here because we just dont see very many 1/2 tons period. Especially big block 1/2 tons. 90% of whats on the road is 3/4 ton long beds.

Do you still have the Dana 60 rear with coil springs?
Is it a full floater?
Are the axles held on by bolts or studs with nuts?

I am need of a 30 spline axle held on by stud/nuts and can't find one around here.

Let me know

thanks, Mike

Chevynut - can you either post or email me a larger pic of your C20 with the camper (i.e., your avatar)? How many of the old trucks still have their campers on them???

...and I have two 1/2T GM Dana 60 rearends, 6-lug. One is a leaf and one is a COIL. Gear ratios are 3:54 & 3:73. The 4X4 guys love these because they bolt in a 1/2T and make it instantly twice as strong. I put one in a SWB 2WD behind a BB and had it converted to 5-lug. Simple install and strong. Springs & shocks bolted right up with no mods.

I am also curious as to why GM used 2 different axles...my GMC has a dana 60, 3.73 (originally 4.10 or 4.11) gears, and most other 3/4 tons seem to have the Eaton. Was this another Chevy/GMC difference or is just random which rear axle you got?

Not neccessarily twice as strong, they still use the same sized axle shafts (and brakes) as a dana 44 uses. *I* like them, but it seems a lot of people don't because they reduce ground clearance from a dana 44.


The Dana 60 FF in the 3/4 tons could be ordered, if you look through the options lists it was one of the axle ratings you could get. They did not call it a dana 60, just gave the weight ratings for each axle.

I figured it was more common to find Danas under GMCs than Chevys, at least in the '66 and back trucks,(44s & 60s) as most,if not all of them stuck to the "GMC/leaf spring", "Chevy/Coil spring" set-up.
After that, seems you could special order leaf or coil under either one. My guess is GM was geared to mass- build 12-bolt stuff with the coil set-up, and GMC spec'd leaf set-ups to Dana, and that's what they built till '67, then they started sharing more stuff between the two lines of trucks. Until then, GMC was viewed as the "workhorse" of the two truck lines,and chevy was the "standard production", but evidently the market was calling for both trucks to be more versatile in their specs. so GM started to offer more options in common.

Maybe an early move to "consolidate" the two truck lines??

After all, look at the '73-present Chevys/GMCs. Same truck, just different badging! JMO!
