Mine's right at the max of 3 3/4" according to the tech after he installed it.
I'll have to re-check now that the Steeda springs are in.
I have a tiny bit of vibration at right-about 100.
Looks like an adjustable UCA is in my future after all ...

The extendable CV joint is just a bit stiff because it's new. Either pull on it harder (watch your fingers) or gently tap it further out.

You have the adaptor installed, right?
adaptor is installed, just needed to pull real hard to get it extended - I was chicken while it's up on jack stands 
thanks for the call skwerl and greg!
it's all buttoned up, just need to realign my exhaust and then take a test drive - but I need dinner first...

Glad to hear it all worked out, enjoy it!
ugh, vibration @ ~30mph, ~60mph and ~100mph...
I'm so bummed right now I don't even want to get back underneath it; and to top off the shitty test drive I scraped my passenger mirror putting it back in the garage...
fwiw, I'm right at the 3-3/4" max measurement recommended on the notes that came with the shaft. I'll call DSS later this week to discuss (i.e. adjust pinion angle or clock it 90deg).

Oh no....and I thought I was just joking when I told you on the phone I hope the next post I see is not about vibrations........I think I jinxed you!
....I think I jinxed you!3.75" is where it ended up when bolted up, so I figured I'd drive it to see how it felt (since it fell within DSS's documented range).
I have a Metco adjustable UCA, set to factory length. I hope to speak with a DSS rep today to get their recommendation on how much to adjust.
greg, I'm sorry for continuing to hijack your thread
I spoke with DSS today, and they recommended I adjust the UCA to bring the measurement (pic here) to 3.5" (it is currently right at 3.75" - maybe a hair over)... and yes the adapter is installed on the pinion flange.
I measured the angle of the transmission flange (+3 deg), and the pinion (+3 deg) prior to any adjustments. I wasn't sure which direction to take the UCA adjustment at first, so I just picked on direction and moved it, and then measured the shaft.
No change.
I went in one direction until I ran out of adjustment. The pinion was moving (angle was changing), but there was no change in the shaft measurement; huh?!?
OK, so I then go in the opposite direction until I ran out of adjustment; again the pinion angle changed but there was still no change in the shaft measurement. No matter what I did it remained 3.75"
Suspension is loaded (car on four ramps). How in the world is the diff angle changing, but the shaft measurement isn't changing at all?
I plan to call DSS back tomorrow to see what they say. I suspect it'll be taking a ride back to them - ugh...

No problem with posting stuff in here, this is good info and surprising since DSS was known for having the d/s's with no issues.

Does anyone know if the carbon fiber DSS has the same vibration issues?
Those are pretty expensive, I don't know anyone in the baller status!
They are only a couple more...i would have bought one, if i wasnt concerned about the longevity of it being on my daily.

It's around $300 more. If it would eliminate the possibility of an adj uca, about $180 and buying a 300 ft lb torque wrench, $$$ and f*@#+ing with pinion angles all day it would be worth it to me
@ skulls~The 2013 GT500 has one so unless I'm missing something I feel it would be fine as a DD.

Its built the exact same way as the alum. one but the shaft is carbon fiber the rest is the same...so its a possiblity you'll still need an adjuatable uca.
As for the gt500 having one, thats great still makes me a bit weary...but i also i cant afford the gt500, so who am i say ;-)

DSS advertises that the carbon fiber one makes less cabin noise. Not sure if that equates to less vibration or not?

Im not a physics person by any means...but i dont think vibration would change much. The noise makes sense, hit alum with a hammer and then hit carbon fiber with a hammer, let me know which is quieter...lol. But the CF may abosrd more vibrations as well.
But i have the alum. one and there is zero added vibration...but it for sure is louder then stock.
