1310 front shaft

[80' 427]

So after finding the bolts loose on my horrible yoke front output on my 205, I was pondering if it is time to consider a replacement. It has enough droop but I do have a BBC and 39.5s. Still I have a spare. Should I still follow the break it twice rule before I swap in my 83 205 and have a 1350 front made?

Might as well...

or just go 1410 and be done!

If my 950ftlb turbo 454 didn't break the 1350 rear I don't think this little na lpg 454 will

A 1350 joint is actually stronger than a 1410. The 1410 just allows for more of an angle

Are you sure about that.....?

The cross/cap size is the same and it's the cap/bearing area that usually limits the torque handling. When you put the same force on the caps, then move them further apart, that's more torque (ft*lbs) through the shaft.

I found this somewhere:

Torque ratings:
Spicer 1310 = 1600 lb-ft, 1330 = 1800 lb-ft, 1350 = 2200 lb-ft, 1410 = 2800 lb-ft.

Dimensions:
Spicer:
1310 Series Large Cap D = 1.125" W = 3.2188"
1330 Series U Joint D = 1.0625" W = 3.625"
1330 Series Large Cap D = 1.125" W = 3.625"
1350 Series U Joint D = 1.188" W = 3.625"
1410 Series U-Joint D = 1.188" W = 4.188"

If I could just find that on the actual Spicer website, you'd be debunked.

Not so, according to billavista....

1310 joint has a max of 800ft/lb and a max angle of 30*
1350 has 1240ft/lb with a 20*
1410 has 1500ft/lb with a 28*

and that info is from Spicer

If you take 400ftlbs, multiply by 6.5 and 2 you get a higher number than any of those values.

 

[Blue85]

Those numbers may be the max operating torque - what they recommend to get good service life. The breaking torque may be much higher. But those angles sure look like max without binding. They generally recommend like 8* max for static operating angle.

What do the Super Duty shafts have?

1330 in the front and 1350 in the back. If 1350 works for diesels then its good for a big block.

I mostly went 1410 for single joints and a BB with a doubler.
If its overkill, I'm ok with that.
