Difference between a Arctic Cat 900t RR and a Sidewinder - reinforcement wise

[tmamayek1]

Does anyone know what parts are different on the Arctic Cat RR compared to the thundercat/or a Sidewinder? I'm interested in knowing what Arctic Cat knowingly admits are weaker parts on the others sleds and am curious about putting said parts on my Sidewinder.

There are only 2 things upgraded on the RR versus the Sidewinder and Thundercat. The cross shaft in the tunnel and the center shock shaft are upgraded in the RR. Easy enough to upgrade in the Sidewinder or Thundercat. Everything else is the same. There are differences from Arctic Cat and Yamaha like clutching, gears/chain and some cosmetic things.

Pretty sure it has the upgraded break disc also

RR has kashima shocks with rebound adjustment. No other models have this on the cat side. There is a few model years that have the shock package.
