Will both of these pistons fit my '97 XTC ?

[Summitt22]

Hey,

So my '97 600 XTC blew up on me yesterday and I'm looking to replace both pistons. I've searched and found that this part number - 8CR-11631-10-D0 is the replacement for my sled.

I found another piston/part number that looks to me like it should fit, but it's significantly less $$ and a very different part # than the first piston mentioned - 8CJ-11631-00-A0

Can anyone confirm that the second piston will fit my sled ? I'm also curious as to why the difference in price & difference in the pistons themselves..

8CR is what you need. 8CJ is for a 500 XTC

This line, and all of the models listed below has me confused then :

"This Yamaha 8CJ-11631-00-A0 PISTON STD part is also used on these models and components:

1997 VMAX 600 XTC - VX600XTCA CRANKSHAFT PISTON"

What's that all about ?
