Just contact the Victory dealer you bought it from and let them know that yours has cracked. They will issue you an RMA and send you a new one. The only real difference in the original and the new appears to be a few extra rubber washers which (to be quite honest, I was a bit leery of originally) appears to stop the new ones from cracking. I was something like the 3rd person to buy one. When mine cracked I waited for the resolution and may have been the second person to have gotten the solution. I've had no cracking since the replacement some 6 months ago.
It's not just any victory.... It's MY Victory!
