What c.v. joints are the go on a bay kombi that will be driven off-road? Standard, 930 porsche, syncro etc. are all options but I will be modifying the rear end for more travel. I know range rovers have the most travel out of all independents but my local rover dealer wanted $750 per joint!!!!

Depends how much travel you want and how much money you have to spend.

Standard they run the Type 2 CV joint. Which will give you reasonable travel and strength.
Then you can go to a Type 4 CV, which is the same bolt pattern but will net you a little bit more travel.
From there the sky's the limit providing your wallet is big enough.
You can go to Porsche 930, 930 race prepped, or even 934.

What suspension are you running and how much travel do you want??

It's standard now but I was hoping to get another 2 inches or so. I was quoted $100 for reco porsche 930 c.v.s , does this sound right? Do I just notch the spring plates for extra travel?

to use the 930 or commodore CVs youll probly need to do what i did , change the inner & outer flanges to suit the larger diam bolt pattern

i used BMW 7series E32 CV joints & axles on my duel cab , if you`re interested

you can buy chrome molly inner flanges to suit from USA & "Trik-offroad" down south can do the outer flange mods/change-overs for you

Hi

Are Commodore CVs the same width as 930 CVs, if there not they wouldn't have the same angle of operation.

This site has useful info on CVs http://www.blindchickenracing.com/How_to/CVJoints_Axles/cv_joints_101.htm

The Commy joint are the same diameter, but narrower so no good for angles. I've had 930's fitted to my old bus, they are still going strong today, some 13 years later.
To fit the 930's as said above, flanges and axles are required, the BMW option is cheapest, find a BM dismantler and you'll save bigtime.

More travel...now thats a bit more work. Firstly shock length is the limit, then axle length. Longer shocks are available, I think '95 F250 rears are the go. Notch the spring plates for increased down travel until axle lenght at full droop becomes an issue, from there things get difficult.....

Yeah the Commodore are just the same diam & bolt pattern/size is what i was getting at, but the fact is you need to change the flanges (like Matty B said) is what i meant

Bimmers alow a bit more angle, but the porsche ones are the better for more angle,,, & you can have a "Play" with them for even more angle if need be

Longer Empi axles are not very expensive, i bought a set a while ago but ended up fitting the Bimmer ones. DB ended up with the Empi`s i think
