[Closed] A Pike/air shaft technical question and total stealth ad

So I have these 1st gen 29er Pikes:

And Simonlovesrocks wants to know if they can go to 160mm. I initially thought no, because when they came out 150mm was the longest. But then I thought, that's because everyone thought 160mm 29ers were insane back then. And then I found there's a 160mm airshaft for the A1 29er like mine:

What I don't know, is if it's automatically compatible- it's always possible there was a chassis change. Does anyone know for sure? The serial number if it helps is 46T31690274

Cheers
