Super-Flex U-joints?? Anyone use them?

These look pretty cool... If they actually allow 10* more deflection then they are worth the price ($60-$70) for sure!

While I've not used them at all, they are made by Tom Woods, who is a reputable manufacturer.

id really like some info on them as that would cure the bind on my front shaft. im curently using a chain to limit droop on the right side.
acording to TW they cant be used on any shaft spinning at road speed due to vibes. i guess my concern is how strong are they for that kind of $$

As long as they're strong enough, they should be a pretty good thing. Any word on how they hold up compared to standard joints?

Are they stock in all tom woods shafts? I have em front and rear in my XJ, and im pretty sure the seals are yellow.

If thats the case, ive never had an issue with em!


EDIT: Looks like I have is 'regular' gold seal U joints. They are quality pieces.

I cant find where it says that... Their site does say:

"We fully expected that at some point, we would find the vibrations to be unacceptable our amazement we didn't experience anything annoying until we reached a speed of about 72-73 MPH. I believe this would be about 2300 RPM on the drive shaft. This drive shaft was also about 2X heavier than stock as it was one we made with a 2" X .120" wall tube."

That statement sounds like as long as they drove under 71 mph the vibes were less than annoying. Of course, that test wasnt even with a stock shaft. So...

I talk to TWoods and you can only use one of them per shaft and only non-CV application. By design they offset the yoke and create a woble that does cause vibration. He told me to only use One at the front axle yoke. I didnt do it but instead limited the axle droop to prevent binding.

I've got 'em the my flattie. Had them in there for years. I run them on both sides of my 1310 front and 1350 rear driveshaft.

Running them on both sides DOES make a huge driveline vibration, but other than regular runs to the local cruise show or around town in Moab my flattie isn't street-driven much. It's a trade-off. They're a means to an end. Without the offset-trunions, I'd have to really limit my suspension droop and that's not really an option since my flattie is set up with more downtravel and less uptravel.

They have proven really strong. I keep a spare 1310 and 1350 in my parts bin just in case on the trail, but haven't needed to bust them out yet. I've abused the snot out of them and so far no breakage. I haven't done any destructive testing on them, but I'd think based on my own usage they're as strong as their Gold Seal inline-trunion counterparts.

wfoconcepts makes a tall dana 60 yoke that gives you a little more angle.

Yeah it has yellow seals in all the u joints in both shafts but the back u joints aren't offset, just the one at the front output of the transfercase. They heldup with the front tires coming off the ground and spinning in mid air and landing, and all the rocks i've drug my Jeep over.

I have one in my front shaft as well. Although I put it on my t-case side as thats where i was having the binding issues... Like others mentioned, vibrations at about 20ish and seem to mellow out around 30... but I RARELY ever go that fast in 4WD since I RARELY drive the Great Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley Moogley thing...

Been holding up so far!! Probably should grease it before winter actually...
