NEW PRODUCT ANNOUNCEMENTS – CV Joint Axle Adapters and Kits

SACC Restorations is extremely excited to announce some CV joint products that are geared towards both the do-it-yourselfers and folks that would rather buy a bolt on product.

The first product is for the do-it-yourselfer…



The Pantera High Performance CV Joint Axle Shaft Adapter Kit. For the do-it-yourselfers this kit consists of 4 CV joint adapters that allows you to create your own CV joint axle kit using readily available parts for the remainder of the axle assemblies.

These adapters allow you to bolt up 108mm Porsche CV joints (930) to the ZF and Pantera Stub Axle. The adapters are fabricated out of 4130 chromoly to reduce weight while maintaining strength requirements.

The CV joint adapters will center and bolt up to your ZF Axle Flange and the Wheel Stub Axle while maintaining the water and air tight integrity required for protection. Another nice thing about these adapters is they are thicker than what others have made. This gives them 2 advantages:

>The first advantage is they are stronger than the others out there.

>The second advantage is there is no center cutout in the middle of the adapter.

The nice thing about this is you can completely assemble and grease them on your workbench. Once assembled, the greased areas are completely contained. The axle assembly is easy to install and it takes the messy part of running CV joints out of the picture. If you have ever had to install a pre-greased CV joint on a car, you know what we mean. Messy job, these adapters do not have the center hole so no mess.

____________________________________________

The next product is for the guy that doesn’t want to search for the parts to put the kit together or worry about what is the correct axle length, etc. He doesn’t mind the messy work of greasing the assembly or torqueing down the 24 CV to Adapter bolts.



The Pantera High Performance CV Joint Axle Shaft Kit – no grease. This CV Style Axle Upgrade Kit uses the 108mm Porsche CV joints on both ends with protection boots to keep in grease and keep contaminants out. This kit includes the Chromoly CV Joint adapters offered in the adapters only kit mentioned above.

To continue the build out of the axle assembly, high performance 108mm CV joints are used but the stock cages are discarded and upgraded to Chromoly high performance units. The full floating axles are also made from high strength Chromoly and have been cut to the correct length for the Pantera. SACC Restorations also machines axle retaining clip slots at the correct location to prevent the full floating axles from crashing into the adapter cups during axle plunge.

The axles are torsional by design which buffers shock loads to the ZF, thus potentially saving you thousands of dollars in ZF repair costs.

These axle assemblies come completely assembled however they MUST be greased and the bolts torqued prior to installation.

____________________________________________

The final product for this announcement is for the guy that just wants to buy the axles and install them without the fuss and mess of having to grease the CV joints and torque the 24 CV to Adapter bolts.



The Pantera High Performance CV Joint Axle Shaft Kit – greased!

This kit is exactly the same kit as the previous kit except that it comes completely greased and the 24 CV to Adapter bolts are all torqued to 80 pounds.

This is truly, a bolt on upgrade!!!

Let me know if there are any questions...

What are the advantages of these CV-kits over the original axles ?

Less power loss in the drivetrain?

Weight?


U-Joints has the characteristic of causing the drive shaft to actually speed up and slow down with every revolution of the shaft. This behavior is counteracted upon by the U-Joint at the opposite end of the shaft, so the user never feels this affect. This is really only an issue if the drive is running at an angle and the more angle, the worse the affect. So in the Pantera, this issue is minimal. The CV Joint doesn't suffer from this affect. As the abbreviation suggests, it is a Constant Velocity joint. So in theory, it does run smoother, especially in higher angle situations.

One could argue that they look way better and modern and don't have the tendency to throw off grease like the U-Joint do...

If also provides more clearance for the exhaust and sway bar.

I would argue that it is stronger, especially if you upgrade to M300 axles.

The axles are also torsional in design, so they are MUCH easier on the ZF. The driveshaft’s will transfer all the shock loads they experience straight to the ZF, but the torsional axles will buffer these shock waves and potentially save you thousands of dollars in repairs for that one burn-out that experienced wheel hop, that you shouldn’t have done!

And finally, and this is a biggie, if the CV joint breaks, the axle should stay retained in the joint, and not pound the hell out of the car.

Not sure about less power loss, but I wouldn’t bet against it…

I do not believe that the assembly is going to save much weight at all. In fact, the CV joint setup may be a pound or two heavier.

NIce looking pieces- I've seen them at POCA Fun Rally displays and they are well-built parts. The so-called 'Super-ZF' built in the mid '80s for BMW M-1s used CV-joint axles stock, and the inboard stub axles were machined for CVs so no adapters needed on that end. There are rumors of very late wide-body Panteras using these ZFs as-stock. Not sure about the outboard stub axles- '88-90 GT5-S Panteras are pretty rare. Lloyd Butfoy could answer this one. CV-type inner stub-axles directly interchanged with standard Hooke-joint stub axles but are very hard to find today. They were also used in at least some of the 15 or so ferocious mid-engine V-8-powered 'Giocattolo' Group B's built by Paul Halstead '86-89 in Australia. One '71 Pantera in OZ is using a Super-ZF from a crashed Giocattolo but with std halfshafts.

A few owners over the years have adapted Porsche Turbo or BMW 735 CV axles to their Panteras. Besides the expense and weight, the only negatives I've ever heard re CV axles is the need to carefully index the outboard rubber boots to avoid contact with the Pantera's exhaust pipes, which are hot enough to burn through the boot, leak vital grease out and fail the CV joint. Lost grease is a death sentance for CVs. This is especially critical if you're running larger-sized exhaust pipes.

I do run CV's, and am very happy with them.

They should eat less power, but for me the main benefit was they don't throw grease around, are almost maintenance free, better balanced (I had much less drivetrain vibrations since I installed them), are less sticky (a better suspension response), and the ones I've got are somewhat lighter too (-2,52Kg for the complete set to be precise). CV's are sure one of the better investments I made in regard to #1239.

I also fitted 930 CV joints, made up my own adaptors etc.
I noticed straight away a smoother transmission of power when pulling away from a standing start.
I run my exhaust over the axles & not under.
There is much more clearance that way.
Total weight saving is around 1.5 kg, so it’s not huge, but still it’s a good thing.

In regards to the axle staying retained in the joint if a CV fails depends on if you are using retainer plates on the outside of the CV.
If you have a pressed steel or machined steel boot flange this does the same thing as they slightly cover the ball tracks in the CV joint body.
This plate stops the balls sliding straight out.

Regards,
Tony.

Unless the axle itself breaks, the axle itself should stay retained in the CV joint on our kits, if the CV joint fails. Unlike the current drive-shafts that will FOR SURE beat the hell out of the car...

Scott,

Do you have pictures of your kit installed. I'm curious to the clearance of the rubber boots to the exhaust and the other hard parts down there.

Steve


Hi Steve,

Here is a picture of the old boot we were using. As you can see, it isn't tapered. It has the same diameter from the beginning to the end of the boot. Even with this style boot, there is plenty of clearance to all moving parts and the exhaust.
