The OE bushings are pressed in with an outer metal sleeve (at least the bushings inside the LCA's are). I'd imagine Honda might sell you replacement bushings but I don't know for sure. If your concerned with handling and willing to sacrifice some ride quality, polyurathane bushings like those from Energy Suspension are a good upgrade but can be challenging to install.
