Lifetime warranty RZR axles at Oreilly's
 

I just installed a new rear axle in my 08' RZR 800 from Oreilly auto parts. It was around $150 including shipping (special order). I had found cheaper 1 year warranty ones online but I was surprised to see Oreilly's had a lifetime warranty. It only took 2 or 3 days to come in to the store.

good luck! I hav broke about every brand off ebay at outer cv, the warranty is nice but you get tired breaking them every few months and ruining your day riding

Put it to the test and let me know if it holds up! RCV needs to come out with one.

Are they for a 50" rzr of a rzr s?

Mine is not an "S". They can probably get any of them. I think the part number is pol7011 for the one I got, search it and see if there is a list somewhere.
