2 will do
I put this on my 2019 Polaris RZR Trail & along with a 27" tires, this was enough lift to get the ground clearance to get over bigger rocks & logs & not sacrifice lateral stability, although I do have an 11" rear tire with 1.5" wheel spacers, so it's a touch wider in the rear than stock. Easy enough to install, but there where no instructions in the box, thankfully, Super ATV has PDF versions on their website that are easy to find & download. I like it & recommend it.
