Honestly I was going to go straight to ride 45, but then some one at the track told me he pretty much had to Buy a whole new gear diff when he was going to try some else so that's why I stayed away. Craig said it was easy to remove so I don't know. If I sell some stuff I have laying around ill buy a new diff and try it out.
