The actual geometry of the suspension is different. More travel. Can't use piggyback shocks from the sc3 in the sc4 but can use them from the sc5. The sc3 is more rear shock driven while the sc4 is center shock driven which is more suited to rider forward sleds.
The first year rev chssis used the SC10 III and went right to the SC10 IIII the following year. I read in a few articles that the III wasn't well suited for the forward riding position sleds, which is why they went to the IIII
I would assume that the SC10 IIII wouldn't be great on our chassis but I've never personally tried.
