If you google Proshaft llc his ebay store comes up as before, but there are now no items listed where previously a very nice picture of a DII front popshaft came up. I checked the other day to confirm the price when I was putting a list together of some front propshaft options and prices for a post.
Just wondering if anything has changed.

Ill contact him and see whats going on. Feel free to give him a call or send him a email as well.
**Quality Update**
I had Proshaft's / Justin's drive shaft in for a second opinion on the build quality / parts of the drive shaft and a local drive line shop had nothing but good opinions towards it and were actually surprised at the what I paid for it.
A second opnion from a mechanic who has 30 years of building engines, and racing cars was much of the same. He couldn't believe the price I paid and gave it a thumbs up for the splicer u-joints that have been used on it. This guy also has used Tom Woods shafts in the past and said that this shaft would be on equal grounds for quality - he didn't say it would be better nor did he say it would be worse just to be clear.
Both didn't have anything negative to say about the driveshaft. I will now install it knowing that it is not some incorrectly built, cheap shaft that's going to blow up on me!
Cheers!

Okay, so I admit I gave up on page 13, but lucky 8 sells a 2 joint Tom Woods for $298, just not the double caradan. That is same price for a proshaft, right? Am I missing something?

Again Im not an expert on the matter but I think the double caradan setup is there for a reason..... I dont know why exactly but I think it increases flexibility/rotation at angles. I would not dare replace a double caradan propshaft with a standard 2 u-joint propshaft. Are you sure the shft you saw is for the front?

Hello all,
Sorry I've been absent from the forum as of late. I do indeed still have drive shafts available. In response to the member who asked about the need for the double cardan in this particular application: the angle that the drive shaft runs dictates that a double cardan be put in place. Running a simple two-joint style drive shaft would put far too much stress on the journal ends of the u-joints. Again, I stress that if you guys need to get in touch with me, please use my contact information in my signature. I typically reply to most emails within a few hours and hardly ever more than 24 hours later. You guys who have supported me and also the guys who have offered constructive criticism are greatly appreciated and you have contributed immensely to the betterment of the product and the operation of my young company. Thank you again so much!
All the best,
Justin
edit: I just listened to a voice mail from a customer who mentioned that someone was asking about my ebay listing. It's back up and running with new pics! I had to call them yesterday to finally get my "listing limit" raised. Apparently they now impose a temporary listing limit for new members. I'm still no great photographer, but I used a pretty expensive camera to try and take better pictures to make up for my lack of talent.

Justin - Glad to hear you are still in business. I don't need a driveshaft but yours certainly seems like a good option for those looking to upgrade from an OEM oned.
Ebay kinda' sucks, but that's the first listing for your company when you google the name. Makes it hard to sell something when nothing is listed. You should work to get a website up and running so you don't have to pay them a cut of what you sell.

The reason for having or not having a DC in a propshaft is dependent on the relationship between the output and input flanges.
1 - The transfer case output shaft is parallel with the ground. If the diff pinion is parallel with the transfer output shaft (even if in a different plane) you want single cardan u-joints (up to a certain propshaft angle).
2 - If the diff pinion is pointing at the transfer output you want a DC end at the transfer case.
If in number 1 the angle is too great you'll need a DC on both ends.

Anti is spot on here with his description once again. The ability to install double cardans on both ends of the shaft is especially handy if the transfer case (or differential) can't be "clocked" in order to improve the angles that he's talking about. Thanks again guys!
