I'm rebuilding one side of my driveline at the present, using the solid Spicer joints (supposed to be, anyway) I've ordered from Van Steel. They recommend the solid joints over the ones with the grease fitting in their website ad, give some good reasons for using them instead of the greasable ones.

And, I think the solid joints coming out of my '66 are origilnal, I've owned the car since it was 10 years old, I've never changed them until now.

has anyone track tested these badboys? I'm just thinking the large body with no hole drilled in it for lube would be stronger than lube type.

That's one of the quoted advantages of the solid joints over the ones with lube holes, but I'm not aware of any tests.

That's not where they break.

They break at the end like all the rest.

Use them in all my vettes. The 75 was built to 370+ hp and then beat into the ground until the posi case cracked in half. The spicers were still good, a 2nd diff installed and blew the tranny, the spicers still are in the car. Is that a good enough test? The new rear tires were bald at 8k miles.

What we (Keisler) have found is that greasable u-joints typically break at the body of the joint where they are drilled to accept the zirk fitting. That's why we now use solid type joints.

Just some information for you.....

The 1310 joint is 3 1/4" across the caps and a 1 1/16" cup diameter. It is rated at 400ft/lbs continuous, 800ft/lbs short duration and 1600ft/lbs breaking point. Spicer # 5-785X.

The 1330 is 3 5/8" across the caps and a 1 1/16" cup diameter. It is rated at 550ft/lbs continuous, 1000ft/lbs of short duration and 1875ft/lbs breaking point. Spicer # 5-790X

The 1350 is 3 5/8" across the caps, 1 3/16" cup diameter. It is rated at 680ft/lbs continuous, 1240ft.lbs short duration and 2260ft/lbs breaking point. Spicer # 5-799X.

All the 63-79 use the same 1/2 shaft joints.in this case the 799's. the mid years had the small 1310 DS yokes unless someone installed a larger DS in the past so you have to measure. Look the diff pinion yoke if it has straps and bolts it's a 1330 if it uses U-bolts then it's a 1310.

thank you Richard, that is very helpful, especially the torque ratings.

And GTR....good info also, thanks to you also.

I have a T-400 in my car, so I'll have to measure the driveshaft sizes.

I've been track testing 1350's on the driveshaft and 1480's on the rears for a few years!

All Solid Spicers...great stuff!

You're welcome. I guess I should've added that C2's came stock with 1310's for the driveshaft and so did the first couple of years for the C3. I believe that in '70 they switched to a 1330 rear u-joint.
I don't have any idea what they used on the half shafts as I am only versed in the components of our kit.

Sort of a dark one. That's a custom built Dana 60 IRS made out of a Hemi center section. If you look closely there is a 3/4" aluminum plate that bolts to Dana, then the stock cover bolts to it. I use 3.5"X.134" wall shafts with the 1480's.

Got tired of breaking stuff!




Thanks,

JIM

SOB....$$$ I'm sure....but that should just about hold up to anything eh? I've watched guys zing their stock ring and pinion with slicks on a healthy smallblock. That should take care of that problem.

So far so good.....it has a 9.75" ring gear.....that sorta trumps a 9" Ford and 12 bolt conversion with a 8-7/8" one.

I've been flogging it for a long time. It also has a set of 3.07 gears we machined to fit in it (they only go down to 3.54's on a Dana 60) from a Dana 61. Still like to go highway cruising!
