Clueless on CV shafts

[atvspeed4]

Im trying to find a way to upgrade my CV shafts on my S10 ZR2 to allow for a higher angle, more torque and new A-arms. Is there any existing company or way of doing this, or is this out of the question. thanks

So no one has any ideas?
Is it possible for me to use porsche CVs

I don't know much about S10 CVs but if you need to upgrade them based on angle and new A-arms, then its sounds like they will need to be custom made to a certain length. If you bought the A-arms from a company, give the company a call and see what they say. If the A-arms are custom, then the CVs will probably need to be custom too.

First you need to find out ho many degrees the axle will be at during full droop. i think cv joints only go about 25-27 degrees. to have custom axles made you need to make a mock up axle to adjust to get the right lenght. there should be about 1/2 inch play on both ends at 0 degrees. if you have never done it you should have someone do this for you.

thanks that gives me a great start

If you are talking about front suspension on an S-10, you also need to observe steering angle. You will need to continue using a Rzeppa type CV joint on the wheel end, and use a cross-groove (Porsche, etc.) on the inner end.

A logical path might be to:
a) see if anyone sells an upgrade for this,
b) look at other GM front wheel drive cars for something beefier,
c) look into grafting 1/2 ton parts.

FWIW, if you start mixing parts, the pivot point of the outer CV must be exactly on an imaginary line that goes through the upper and lower ball joints.

Well I have looked around for any companies that would have upgrades but found nothing, actually I couldn't find much information on this ever being done. I did find out something that might be helpful but I need to look into it further, the ZR2 actually runs 1/2 ton drivetrain. The front diff and rear are oversized to the same ones found on a half ton SUV. So I looked at my CV half shafts and they are different then a regular S10.

I did find this link though http://www.off-roadweb.com/features/0303or_1999_ford_f150_super_cab/

I believe there are kits available for the old toyota IFS front ends. You might try looking into that for ideas.

we are working with 930 and 934 style sand and desert cars using u joints -here's a pic 36 degree's and there strong enough for 800 horse- Jess

WOW! If someone could design those for S10's there is a potential for a big market if priced right. I never thought that a U-joint could be used like that.

800 horse?..
Tested?
I am just imagining the loads it will see when a driver stays in the pedal.
that wolud be a great set up if proven.

[Jess@HighAngle]

were actually tested thru 1000 horse- Jess http://highangledriveline.com/images/sandrails/Copy_of_post-10949-1160265188.jpg
