That is right 40 degree CV Joints..
Here is my story....
I am currently running 4x5 dual pivot arms with 0 deg radius and the Transmission is in the stock position. Unfortunately, this combination creates a 14 degree back angle on the CV and significantly limits my travel. To keep from breaking CV Joints, I had to limit the travel on my 930 CV joints to around 15 degrees.
While I was contemplating options to fix the problem, I continued to break CV joints and RVCPerformance continued to honor their warranty and kept replacing the joints.
After replacing several CV joints, RCVPerformance mentioned a new Ball Spline axle they were making and I might be good fit. Obviously I jumped at the opportunity to try something new.
Over the next 4 months, I continued to talk with RCVPerformance about the new axle. Well, I am happy to say that they have finished the prototype and I should have it in my hands next week.
Here is the general idea..... RCVPerformance has joined 2 fixed 930 CV joints to a plunging axles. Rather than having the CV joints plunge, the axle will plunge. I know... I know... the high angle drive shafts guys already tried this. Here is the difference, rather than using a yoke style plunging axle, RCVPerformance is using ball bearings to allow the shaft to plunge without friction. Even under torgue the axle should still plunge without friction. Another benefits over the high angle drive shafts is that RCVPerfomance is using CV joints rather than U-joints.
Using the fixed CV joints, I will be able to extend the motion of the CV joint to approximately 40 degrees. In my case, this will drastically increase my rear ground clearance and allow me to raise up the buggy an additional 6-8 inches.
Here is a picture of the UTV set-up RCV Performance has already developed. The buggy version is very similar but the ends will have 930 CV joints.
When RCVPerformance tested the new ball spline axles, the axles have the same braking point as a Dana 44. I think that will work fine for a 2000 lb buggy.
I will take several pictures of the axles as well as Before and After Pics of the buggy.
