Nytro Secondary Replacement

[MatthewW14]

I started going through my 2010 Nytro turbo sled for next year and noted my secondary is cracked. I have seen spider cracks before and not worried too much but there are a few bad ones.

In looking for a replacement I found some apex, vector, etc Yamaha secondary clutches for cheap. Are they all the same as far as the sheaves.buttons, etc go or is the Nytro secondary different in any way?

The Nitro jackshaft has a different sized spline than Apex and Vectors do.

Perfect- Thank you for the info. I will keep my eyes out for a Nytro one then.

I just replaced mine this winter cause it looked like yours. What is this from? Heat, extra torque , high miles?

Viper is the same.

CR Racing in BC had a few kicking around so I got one from them. I was told heat and then getting snow on it could cause it. I am thinking the heat/extra torque is the culprit of it.
