Could someone explain the different CV types and their application for me? I think I have it understood, but I'd rather be sure.

Who is a good source for type 4 cv's. Also are they all the same or do they have heavy duty versions?

Someone is bound to ask, so I'll be the first...what are you trying to do with them?

Is this for a pilot application?

It's not for a pilot. I have an old buggy that has type
4 cv's. I'm finding it difficult to locate replacements. Some say go to a
Type 2. Some web sites say it has less articulation than a type 4 others show
Off road ones where they claim up to 25 degrees. Don't know much about them
So right now I have more info than my brain can process. I would like to use 930
Cv's but I don't want to buy new axles.

How much angle do you need?

I think the type II CV's can be modified for a few more degrees angle Dave-Co or some of the VW guys can confirm this.

Why not just get some more type 4's?

You go talk to the guys at the Old Volks Home I think they just down the street from you?

Actually...I was asking about cv's For a pilot application. I want to run a 670 rot ax or so, and convert to 930 CV.

You'll need a flanged stub shaft with the pilot 25 spline male end

I don't know of one off hand but maybe someone here has a source

OK...a better question yet. What trailing arms would be the best matchup to start with ordered. I don't have all the equipment at hand to make my own. I can do some fab work, but I'm converting to a 930cv setup due to part options/availability with a 5:1 gearbox. My 670 ho has all the power I need....lol. Also to widen the rear end some and to have a better suspension. The problem I've seen, is their all a arm form, or too long, etc. I just need a set with the correct length, micro stub axle supported, and angled enough to widen it about 6-8". I'm waiting on my Honda 450r a arms to get here so I could get exact measurement, but I'd like the rear to be the same width. Any suggestions?

You can buy modified 930's with 28-deg of motion (they add 3-deg), but they ain't cheap. That's about the most you'll get out of a standard V-dub axle.

Given a "Z" axle length, doing the math...
Z = 14": Sin28 x 14" = ~6.5" of travel each direction (total of 13").
Z = 16": Sin28 x 16" = ~7.5" of travel each direction (total of 15").
Z = 18": Sin28 x 18" = ~8.5" of travel each direction (total of 17").
Z = 20": Sin28 x 20" = ~9.5" of travel each direction (total of 19").

Type II 25 degrees? http://www.thesamba.com/vw/forum/viewtopic.php?t=266658

I am sure if you take any of them apart you can figure out what the limit is and where to grind to provide more clearance and get more angle.

DMoney...got a lead on where to find those axles? I want to do it as a porsche 930 cv if possible. Also, I decided to convert the fl350 I already have with this mod for now. Not a pilot. Also, any leads on what trailing arms would be good for this mod? A link would be great.
