The last CV you'll ever need....maybe

[Triathlete]

While the stockers, or even my toyota ones wouldn't hold up to 500HP,

934.5 CVs CAN and DO take that HP and tire size!!!! the axle bars are 1.5" 35 slpine just like a dana 60!!! And they even have larger ones...series 50??? avail..... PRO 4 trucks use these....

Yep, just take a look at Shannon Campbells IFS King of the Hammers rig.

Yeah, but try finding a replacement set of those at the junkyard. For the $250 I spent for the whole D60, I'm pretty sure for as rarely as I'll break shafts that it'll be more cost effective long run. Plus I can regear it to just about anything and there's a wide variety of lockers available. I have just never heard of that kind of stuff with any of the IFS out there that isn't totally high dollar custom made. Add to that the fact that my solid axle route is way more hydraulic steering friendly, and probably articulates waaayy more, plus more weight down low vs. IFS and I'm sold on it.

I was just throwing that out there...believe me, if I had the $$$ there would already be a solid axle under mine!

Updates? With Bigmeat's new super flexy IFS, I'd think people would really start wanting these stronger CV's. I don't how many people watched the videos in his thread, but those A-arm angles are going to eat stock CV's for breakfast. I love that I'm finally seeing some decent hardcore parts becoming available for the VX. Even if it's a little too late for me

Thats what I was thinking, talking with Joe D about it. Definitely gotta stay out of the skinny pedal if you are flexed out...Plus, looking how much flex he gets, gonna have to remove the inner liners, and perhaps trim the outer cladding...no big deal for me, but for some that is probably a deal breaker, although if you want to keep your VX pretty, this kit kind of defeats the purpose. This would be for an actual trail truck, not a once a year, Tour De Desert truck. Not downing those folks, but to spend that much money and time, for a mod that is gonna require some work to make it effective...I went ahead and did the ball joint flip, low pro bump stops(that really aren't any smaller than the factory stops), got the diff drop brackets in the truck...and I have several spare OEM CVs, so maybe if this EMPI deal goes through, I may liquidate all my spares, and use that as money toward the super fancy CVs.

Dont forget that I run 35s and 36 inch tires.... thats where all the trimming is neccesary...
Folks with 31-33ish tires will not need to remove front the inner fenders with the SUPER FLEXY IFS KIT.

Well I'm not really sure what you mean by an axle bar, but I think we are saying the same thing. Yes, I did have a diff drop installed at the time. I did 2.5" if remember correctly, but it might have been 3", it'd been a long time. Even with that my cvs were running constant 30 degree angles just going down the street. I was trying to say in my post above that because of that angle, every time the shaft rotates it cause the balls to do exactly what you are saying-slide back and forth in the cv cups, but it's also causing the cages to move all over the place so they can. If you have a cv with no boot on and look inside when you move it and it's at a high angle you can see this plain as day.

I was thinking about this a little, and I suspect having the weight balanced between the two CVs will somewhat offset the angle effect on CV longevity. I have broken a couple of CVs where one side was trying to climb a ledge or log by itself. With the "SFIFS", the loads are going to be much more balanced L/R (within the limits of IFS travel at least) so there is good chance that the other side will be helping too in that scenario.

But we'll see what happens...you may be right.

[Ascinder]

Yeah, from a weight distribution standpoint, it will certainly reduce breakages, but kind of what I was referring to is that generally when people start putting performance oriented stuff like this in, the tendency is to lift as well, they kind of go hand in hand. I know when mine was lifted pretty high like that, the cvs were seeing some pretty steep angles. When that happens you get a lot of end-range play. What I mean is that the balls and cups are sitting where they are not used to being and at the limits of their allowable travel I think that's where a lot of people are hearing the clicking. If you envision the insides of a cv at a high angle, the cages are also at an angle and so every time the shaft turns one revolution, the balls must travel all the way back and forth in the cup. I think this is the clicking people hear. Obviously all this travel is going to cause more wear and tear vs stock which only travel a small amount and then only when there's any suspension travel. That's the reason I was interested in the cvs that have a splints center shaft that allows them to self lengthen and shorten. It would take away some of the forces present when the suspension cycles. And instead of bottoming out the cages in the cups, would let them ride where they're most "comfortable".

The clicking people hear is the ball(s) traveling in the slots in the tulip and the star, AND hitting a worn or damaged area in there path...either a compression in the tulip or a crack in the star will cause this...

It is NOT the axle bar binding on the side of the tulip.

Did you have a diff drop when you had this lift???

Some CVs allow the axle bar to slip inside the star for more movement...this eliminates the need for the center slip yoke you speak of...
