school me on u joints

[78Suburban]

I'm thinking with my new lift, the angles may try to eat a u joint.. so I figure it would be nice to have a spare or two, or maybe even go ahead and replace them.. How much money should I look to spend, and what brand? what part number would I need?

I have a corp 10 front and 14ff rear, th400/203, all factory parts as of now..

I'm really not familiar at all with u joints, so any basic info would be great!!
thanks,
James

Front joint is a 1310 and the rear joint is a 1350. As far as price I do not know as I have a conversion joint in my shaft and I have only purchased an S44 joint .

12 bolts are 1310 ( some 4 speeds were 1350 , had one ) . 10 bolt rears are s44 ( simmilar but NOT 1330 ) .

so if the front and rear are the same could I use a front cv on the back in between my slip yoke a shaft?

If i am not mistaken there was a post on here a while back with a photo of a Spicer tool (basically a tape measure)...that you just put the joint up to that and size it up.....i just can't find it. And my lazy arse didn't print it out

where did you get this tool at?

A normal tape measure will do just fine...

1310: 3-7/32 X 1-1/16
1330: 3-5/8 X 1-1/16
3R or S44: 3-5/8 X 1-1/8
1350: 3-5/8 X 1-3/16
1410: 4-3/16 X 1-3/16

Off the top of my head, I think they should be right.

Local driveline shop. very common. One side sizes yolks other side is joints. Handy to have.
