Yes you can, I recommend the Energy Suspension ones vs the Prothane ones. I've had the Prothane ones split before and I've had it slip out before has well, both times were two different inserts. The Energy Suspension one I had before last roughly 6 years before finally ripping through. You can get them directly from ES for 25 bucks shipped or you can get them from Massive
in different colors for a little more money.
