Our billet flange has been a huge hit, how does everyone like the fit and install?

I'm thinking about anodizing them red or black.

I'm installing your carbon fiber driveshaft right now with you adapter plate. Ran into some confusion. You supply 7 bolts in total. 3 black bolts to bolt the adapter plate to the differential and 4 gold to bolt the adapter to the driveshaft. Then you supply 8 lock washers.

This is where I'm confused. The lock washers don't fit over the black bolts. Am I supposed to use them on the black bolts? If not, why were 8 lock washers supplied? Am I supposed to double them up on the gold bolts?

The instructions don't mention lock washers at all. But you guys are closed now so I figured I'd see if you guys were on the site tonight. If not, I'll call tomorrow. Thanks ahead of time.

Sorry about the confusion, our shipping guy must have included 4 extra washers. You only need 4 lock washers to be put on with the 4, 7/16 bolts. The three socket cap screws do not need lock washers.

No worries. I'm not in a huge rush to get this in.

But thanks for the call and for replying to this so quickly. I'll be sure to post up in here once I get it all back together.

No problem, and I'd love to hear about your install with some pics

Well, I'm pretty happy with your CF driveshaft. I was worried about vibrations and turn out it's smoother the the factory driveshaft. I've tested it up to 110mph and it's completely smooth. It feels more connected when you shift and get on it. Probably cause you don't have the extra play cause by the carrier bearing on the stock shaft and it can't flex at the center either. Also it got rid of my clunk and made shifts smoother. Some things I wasn't expecting though were the jingling noise it makes sometimes. I'm assuming that the U-joints. Also, it seems to transmit more gear noise from the trans/diff an low speed, low RPM (less than 1.5k) driving.

Only issues I had installing it was I wasn't able to get any socket on the 4 bolts that connect the driveshaft to the billet adapter. Just wasn't enough room. So I had to use an open end side of a wrench and couldn't follow the torque specs. I also have no clearance issues. It's close in some areas but I have all poly bushings in the rear as well as poly engine/trans mounts so it isn't going to be able to move around much.

I tried to attach pictures of my install but the server to upload pictures to this site says it's down. I'll try again later.

Very nice shaft you have there sir!

Thanks for posting up the great photo's and feedback, we really appreciate it.

You might pay attention to that jingle noise you hear, you might have a loose dust cover on the diff or something. The shaft shouldnt make any noise like that.

Thanks
Chris

Dust cover on the diff? I didn't know there was one. Can you tell me where it is? I'm going to get under there again tomorrow to check for any loose bolts and I'll look for this now. The jingling noise almost sounds like a loose bolt rattling around. It's a higher pitched metal on metal noise.

You'll love it. I just can't believe I was worried about it adding vibrations to my car and it actually did the opposite and removed some!

I thought the flange was more of a triangle rather then a circle?

I like my carbon fiber drive shaft. I have a long video from under my car but you can't see much of the drive-shaft.

There is a dust cover just behind the OEM pinion flange. It might be loose.
Could be a loose bolt somewhere like you said too.

We changed to a full circle to make them stronger, we also changed to larger 7/16-20 grade 8 bolts in the round adapter. The standard is 3/8-16 but we bumped it up a bit

Well I just got under it and I looked at the pinion flange and found that dust cover. Tight as ever with no movement. Same with every bolt and I check most of my rear suspension/half shaft bolts while I was under there also just to play it safe. The only thing I noticed that could cause some noise is the slip yoke. I can push up on the drive shaft part of the slip yoke and it clunks around inside the trans. So it's not completely tight in there. Not a whole lot of play but there is enough to make me wonder. Any ideas?

The drive shaft side of the slip yoke sticks out of the trans about an inch, but I don't know if that's normal or not.

An inch sticking out is about right. Hard to say what it is

I plan to order a carbon fiber shaft when I recieve my refund or before the sale ends. Having trouble decideing if I should get the billet yoke or the adapter. Which one would everyone reccommend?

The billet adapter is by far the easiest to install and it's really strong. We use big 7/16-20 to attached it to the driveshaft.
The billet adapter option is cheaper as well, not as much machine work to make the adapter vs the billet yoke.

Thanks
Chris

Re: Gforce Carbon Fiber driveshaft review thread

I'd love to have one of these someday. If the stocker goes out, an aluminum one may be in order! Gforce makes some awesome components, and I'd love to run their products someday

Thank you for the compliments.
The 3.5" aluminum shaft is a great performing shaft as well.

Thanks

I have the billet aluminum yoke and must say it's probably the best, strongest, and lightest option. The adapter is obviously much easier to install though. Pros and cons to each I guess.

Hey Chris,

Which one is safer for high speed stuff like the Texas mile?(adapter or yoke) I will be looking to make a few passes this year. And also, I need something that will still allow me to make long trips. It's about 5 hours to my hometown in LA and I go there about three times a year in the car so hopefully none of the upgrades would take away from my drivability.

Either one would work fine for that. They really are both great pieces, some just insist on a billet pinion yoke so we make both.

THanks

First drive with the Carbon drive shaft, billet yoke, new rear, Gforce stubs, and Gforce anti wheel hop axles was nice and smooth. Stayed out of boost and went around 110 for about 10 minutes, smooth as silk

I'm confused Chris can you explain something for me.

OK, assuming that the carbon fiber shaft for the T-56 is 13lbs, is that with the billet yoke or the adaptor?

Also, is there a weight difference between the 04 and 05/06 stock driveshafts? Is that why I'm reading the two different 17lbs and 23lbs figures?

Basically I'm wondering how much weight I will save by going from a stock 06 T-56 driveshaft to the Carbon Fiber one with the billet yoke.

I can't say exact figures, but I think my stock shaft was probably more near 23 lbs. The adapter doesn't weight much at all. I'd say with all 7 bolts in it maybe a pound. The CF feels way lighter.

I don't believe there is much of a deference in weight between the 04 and 05-06 shafts. If I remember right the stock shafts are around 23 lbs, not sure where I got the 17lbs from. In all you will be saving around 8-9 lbs by going with the CF shaft. The adapter and billet yoke both weigh right at 1 lb.

Thanks
Chris
