Do the elevate kit it will make your sled ride 100x better. You would need to do a drop and roll chaincase and the easiest way to do that would be with a TKI belt drive. Belt drive + elevate kit and your sled will out handle most if not all brand new sleds. I ride a 17 mtn cat and am planning on an elevate kit for next season. I like my 17 better than the 2020's from any brand.
