[Martins 660]

Anyone here use them? Pros ? Cons?
Will they fit gorilla axles ? They are a little bigger in diameter called norrec they didn't know

I've been using them for a few of years. They seem to be tough haven't had to change one for more than a year on 3 machines.
One size fits all the CV's on a 450 and 700. On the 660 it also fits the drive shaft CV's.
Good price also. I always keep a couple in the garage.
Norrec Industries makes them in Minnesota.
