Highlifter 2″ Signature series lift kit or Rubberdown Custom Spring spacer/lift kit?

Which one should I go with? I need to 2" lift kit for my Can Am 2014 Outlander Max XT. I just recently bought 29.5 outlaw tires on my outty and it rubs a bit on bumps. I have already cut what needy to be cut already, but it’s rubs on the inside when I hit on bumps. Will the HL 2 be too much of my axle, members says it does, but on the website it’s says it’s made for stock axle. I don’t abuse my ride as much as most. Will the RBC be enough to lift my bike?
