Yes it should be. Fortunately the Tora 302 uses a separate air tube instead of using the stanchion as the air tube. If the later was the case it would likely not work as the coil spring tends to scratch the inside of the stanchion over time and would not allow for an air tight seal. But with the seperate air tube design of the solo air spring this won't be an issue. If you can find the parts it should be pretty much a "drop in" conversion.
