DSS Aluminum Driveshaft

Greetings all.
Just to be safe to not violate the -
"Necroposting" advisory, I thought I'd start this new thread just to let everybody know I'll soon find out what it's like having a one-piece driveshaft on my 2012 5.0.
I am anticipating it being a nice, minor thing that makes my Pony a bit more snappy.
A big shout out the the folks at the Driveshaft Shop for helping me get new bolts... since I put the originals in one of my "strategic locations (you know, a place I'd remember them later)"... it took my wife to find everything and long story short, it goes into my shop tomorrow.
I'll be eager to give a report on my findings.
Have a good one everybody!
Mark

I too installed one. I went with Shaftmasters. Excellent pc. Easy install. Buttery smooth. But a couple of good things that SM includes surprised me. New bolts,Loc-tite,A socket for the bolts and a cleanup tap to clean the bolt holes prior to installation! Very nice touch. Shaftmasters had the best price I found. The only downside is that I thought the car would be quicker in the qtr. mile. I've run it numerous times in the past so I knew what the car turns. Absolutely no change in ET or MPH. Oh well still nicer than the bulky stock unit.

Well. After the first week with the ONE PIECE, I can say I like it. I believe to the slightest degree the car feels snappier and more responsive.
I do seem to feel a bit of vibration at around 70MPH but below and above there it's smooth.
Also... not really that concerned about this but I seem to be noticing an up tick in MPG... I have my usual commute tomorrow for school so I plan to test that theory for sure.
Not sure if the Driveshaft Shop would think it needs rebalanced or what but I did also have my tires rotated and I was thinking it could be that until the fronts wear a bit.
Otherwise I am satisfied and even with a little vibration I plan to keep it on for the weight savings. Can't hurt the engine if it's Turing 25 less pounds.
I also had a BMR Loop installed but not sure I'd really need it the way it's tucked up above the exhaust and the mechanic did show me that while on the lift the shafts rubs on the exhaust in the back but while on the ground it doesn't, kinda disappointed with that fitment issue but it's fine on the ground and I don't plan on jumping it to full flex anytime soon.
Thanks for reminding me to post my impressions. Forgot there for a bit.

Well, being a novice, not sure what else I'm supposed to feel.
Since I had it done, my driving has been around town and as I said my highway commute will begin tomorrow to give me more time in the car and under highway conditions... all I've done so far is run the kids around town.
And I would like to do my car performance gps test as well to see my 0-60 times to get some definitive data. But that will have to wait till fall.
And I sold my DeLorean back in November so that snappiness WAS a bit of stupid money, so I really wasn't concerned about dollar-per-HP, it was more of an impulse buy... that and a set of 20 inch Shelby Razors. And two years prior to that, I added a set of Roush Axlebacks (more weight reduction)... so I am curious to see my 0-60 times for sure.
So yeah... don't judge... lol.

I got a DSS AL driveshaft because I didn't like the "clunkiness" of the two-piece unit. I definitely noticed the difference after it was installed. The CV joint is more forgiving of pinion angle setting. For me, it was money well spent.

I didnt notice any difference with mine. I think I'm glad I bought it lol. First one had a defect. Second one is fine. Both sucked to install on jack stands with a lowered stance.

I like the idea of an aluminum driveshaft, even if the difference is not super noticeable. It is an efficiency thing -- getting more of the power that the engine produces to the rear wheels. Any time you can do that, it's a good thing.

That said . . . when I had one in my car, I couldn't tell much difference, except for the vibration under certain conditions (this was one without the CV joint) . . . so I took it out, to be check out and rebalanced if needed . . . . and it is still sitting there in my workshop waiting . . .

I would be concerned about the vibration though. I'd see if the tires were okay but you would've felt that before if it was the tires.

Yeah, that's why I took it out, to make sure there is no issue with the shaft itself.

I noticed a vibration, more like a low frequency hum, when coasting in neutral at highway speeds. I figured that was the driveshaft vibrating around a bit, since it had no load on it to keep it from moving around.

I'm pretty sure it is just inherent vibration due to the "phasing" issues in the drivetrain; due to the fact that the orientation of the transmission in the chassis is not optimum, so the transmission/driveshaft and driveshaft/pinion angles cannot be perfectly equal and opposite like they "should" be.

Yeah. I need to get that checked. Not sure why it would be doing that given that it was balanced from the DSS. I have to look for a shop that can balance it again and check my set up to see what's up.

I too find the vibration to be troublesome. I ran mine up to 120mph and it was smooth thru the whole mph range.

Right. I took mine to almost 120 as well and it only does it around 70mph. You know, cruising speed.
