RCV Performance 930 CV plunging axle

[stress]

On RCV Performance website they show a plunging axle they make for a Polaris 1000 rzr . They make custom 930 CV plunging axles , they do not show this on there website. The axle came with CV boots, CV boot flanges and CV bolts. The axle requires you use a non-plunging CV on one end of the axle, you can use a plunging CV on the other end of the axle. I got the non-plunging CVs from RCV Performance, the end of the axle spline that goes into this CV is larger in Diameter than a 930 CV plunging axle. So you need to plan which end of the axle will have the non-plunging CV. The axle acts like it has a return spring inside it, if you compress the axle and let go of it the axle will pop back to full length. The axle has 3 inches of plunge. The axle uses ball bearing in slots to prevent the axle from binding under power and braking. See the Link for details on how it works. This axle is suppose to not have the binding problems that spline axles have. I have not drove the buggy yet.

Axles on the buggy. The axles have 2 inch clearance to the trailing arms the pictures make it look like its less

Its a really cool part but double plunge? Do you need a plunge axle With a plunge cv? I always thought the axle plunge was so you could run two NON plunge cv's..
Hmmm..

Cool, super travel now. Kfab had a set of similar axles a while back on the dez. We had used those splined shafts with ball bearings successfully on a few projects.

It may just be my ocd side, but they should have necked the axles down after the splines to prevent them from causing a stress riser. They will either fail there, or at the snap ring before the sliding splines.

Another small rant, but what is with the money gouging monopoly on non plunging 930's? $280 bucks? C'mon! I paid 180 each 5 years ago.

Holy ouch, I thought 180 was steep 4 years ago. I'll stick to cannibalizing F150 stuff. If F150s fail, time for GM 1-Tons- same old 33 spline stub (might need some clearance cuts). But one needs to be ready to pony up for custom axles.

I was looking at them thinking the same thing- where's the twist section?

I have mid-board hubs on my trailing arms , the hubs have plunging CVs. That is why I have have a non-plunging on one end of the axle and the mid-board hub plunging CV on the other end of the axle. Non-plunging CV are about 3/8 inch narrower than a plunging CV. Since the CV is inside the mid-board hub you can not put a CV that is narrower and still be able to assemble the mid-board hub.

On the RCV one piece straight axles the ends of the axles where the splines are cut are a larger diameter to reduce the stress riser. The correct method.

When I got the axles I saw how they cut the CV splines into the axle shaft, was surprised with how they cut the CV splines , making a stress riser. That is why I showed close up the splines in the pictures , to show how they did it. After the custom axles shows up in the mail its too late to do anything but to hope for the best.

I hope they work.

I had horrid problems with plunging axles and there's no neck down on the splined area, so there's gonna be a huge stress riser there.
