Hello!
Since I'm swappin' the tranny in the Z, I figured I'd do some maintenance while I'm at it! I've searched high and low for confirmation on this, but do any of you know which u-joints are stock replacement for the LS1's aluminum driveshaft? I've found sources that say the 1310, some say n3r, some say 1350 (but I believe that only relates to those with the 9in rear)..

Thanks in advance!!!


(Side note: Any suggestions for me on any other maintenance I should do while I'm at it? The car has 142k miles, so I'm changing the flexplate, rear main seal, and hopefully the u-joints. I changed the rear diff fluid 30k miles ago, so it should be good....)

Any thoughts on this?

Here I go, answering my own questions again.... for posterity's sake

The best I can gather is that the inside yoke span is 2.556", and the bearing cap diameter is 1.124". The u-joint type is the n3r.
TCI makes the 961300
Lakewood makes the 23011
Neapco makes the 2-3011, 2-3011 BF

If anyone else would like to add alternative Universal joints that you've used, feel free!
I'm ordering one of these tomorrow, so if I'm wrong, someone please chime in!

Im thinkin it is a 1310. I believe i had to buy a 1310-1350 joint for my viper output shaft yoke. let me see if i can find anything on it.


EDIT:
Heres what came up on Napa for an 01 Firebird:

Why can't you just go to your favorite auto parts store and ask them for two u-joints for your application?

The napa u-joint looks to match the specs of the n3r.
Luckily, the lakewood n3r is what I ordered, so I'll know for sure on Monday!



Because I've been given misinfo and wrong parts too many times to count. Brake pads, rotors, drums, bulbs, alternators, transmission mounts have all been wrong at one time or another... I am trying to gain from and add to the great knowledgebase known as ls1tech.com...
Just think... The next person to search for factory u-joints will hopefully find the correct model, specs, and a few part numbers to think about. (Which is something I could not find on here....)

It's really going to suck if you get the wrong ones from mail order.
That $37.95 (plus $shipping) lakewood u-joint is the same as the $9 brute force at autozone and the $12 Spicer at napa.

It's not a bad idea you have there really. I'm just suggesting that you can do the same thing locally.

That lakewood u-joint is a waste of money. It's not going to give you more miles than a spicer.

you're not really adding to the "great knowledgebase", it's already there.
