2015 sportsman 850sp lift and axle length questions

Ok so I put a outkast fabworx 3" up 2" back lift with arched control arms on…I also put heavy duty springs in it…so between the lift and springs am I gonna need longer axles? I know I can’t be the only guy to lift and put springs in…I plan on buying axles anyways just wanna know if stock length is ok or do I need longer
