I have a 2012 pro, 08 270 MCX Nytro, and have a 2014 270 MCX Viper. I think I know the sled you bought and the only thing missing IMO is a spindle forward front on that sled if I remember it had stock front A-arms.
My nytro has the +3 Zbroz front with stock Yammie shocks with EZ-Ryde rear, the reason I mentioned my pro is this. No matter what some of the stereo type opinions are out there on the 4 stroke sleds ( ie. Nytro, Viper, 1100t) they can and will handle as well as a Pro or any other two strokes. I can put my Nytro anywhere anybody else can put there Pro including myself, thru the trees, any technical terrain. I can side hill my Nytro till I run out of terrain just like my Pro. Big difference is when it is Deep, Deep, Deep, and pro can't my Nytro still can. The best aftermarket option for a Nytro is a plus 3 or 4 front a-arms, you would not believe the improvement it makes. Once installed your Nytro will pull up on its side as easy as your Pro.
My buddie has a 270 MCX Nytro with stock rear skid and +3 Zbroz front. I have rode this sled numerous times and it is a dream to ride thru trees as well, but being an uncoupled stock suspension it does have more ski lift than mine. He is suppose to ride with us this weekend so if I get a chance I will look to see where he has things set.
