I am new to CFMoto and just purchased a Cforce 800 XC.  I wish to install 30" tires and a 2" lift kit otherwise staying stock for now.  I ride mountain terrain and need low end power mostly.  Looking for spring/weight part numbers or sizes for this setup if anyone knows.  Not much info online that I have been able to find to date.  Any help before I fire the parts cannon is appreciated.

People will chime-in with some parts numbers but...with 30" tires and a lift kit on an ATV, you may not like the feel in mountain terrains...especially in off-camber situations like rock crawling and steep climbing. That setup is more for mud. But..maybe your mountains are different from ours down here.

What NM said. Also, what's the reason behind the 30" tires? Those will absolutely kill low end power and what many people don't consider, will make braking require more effort and create more heat.
If it's just about perceived need for more ground clearance I'd say it's much better to get yourself a good skid plate and if it encounters the odd rock or log in the rough stuff, that's what it's made for! You'll have a peppier and more stable ride in the long run.
